Custom Manufactured By. It is important to read and understand all instructions. For your future reference: Serial No. Date of purchase found inside battery compartment) Name and address of dealer Included Accessories: AC Adapter Item Code: FMA. Purpose The FM Transmitter is designed to transmit any audio to any FM Receiver. You can transmit satellite audio to any receiver or car stereo, transmit Internet audio from your computer to your portable radio, and also transmit audio from your MP3 player to your home stereo or car. Tune your pocket radio to the transmitting frequency. It will also operate on the included (2) “AA” size Alkaline batteries. Battery Installation 1) Open the cover by pushing down on the textured tab firmly and pushing the cover off toward the side of the unit, the same direction the textured arrow is pointing. The higher the transmitter is located the better. Keep metal objects away from the telescopic antenna (meaning not touching or within 2” of the antenna). The transmitter can be helped by placing it on something that will act as a ground plane like a metal filing cabinet or a refrigerator. If that doesn’t help, try adjusting the volume of your audio source. No Audio: 1) Verify the power on the FM Transmitter, your audio source and your receiver is on. Location Frequency FM Transmitter Page 11. Heat: Never put the FM Transmitter in direct sunlight in an unven- tilated area or behind glass such as a car's interior. The transmitter should be kept away from heat sources such as radiators, heat registers, stoves, or other appliances that produce heat. Removing the cover may expose you to dangerous voltage levels and will void the warranty. Refer all servicing to authorized service personnel. REFER instructions are included in the SERVICING TO QUALIFIED literature accompanying this PERSONNEL product. Service Information If your unit requires service call C.

I have one connected to my desktop PC’s sound card output through an audio processor. In this configuration I can broadcast my music library to radios all around my house and out into the back yard. When guests are over I put on a radio in every room and it creates a wonderful effect. I use several of these. I have one connected to the output of my Eton E1XM Radio so I can hear XM all over the house. With my previous car which lacked an auxiliary audio input I used the FM Transmitter to play my IPOD through the car stereo. The possibilities are endless for a device like this. It has a coiled audio input cable with a stereo mini-plug on the end so it can be plugged into most popular audio sources such as an MP3 player, computer sound card or any audio source that has a headphone or line out Jack. It has a volume control and LED volume indicators to set your broadcast volume level (modulation) accurately. Put in two AA batteries or plug in the supplied AC adapter and you’re on the air with your own FM station. More recently I tried one of those FM transmitters sold from China via eBay. It also had diminished bass frequency response. I even had to use an external antenna mounted in the attic to reduce the hum but the distortion persisted until I finally canned the whole system. For several technical reasons it is difficult to design an inexpensive FM Transmitter that sounds even remotely as good as the real FM stations you find on the dial. But there has been one thing I wish could be improved about it and that is its signal to noise ratio. There was a subtle background noise which was audible on wide dynamic range material or in between songs when listening at higher listening levels or in earphones. It was subtle enough that many users never noticed it and in daily use here I must say it was seldom an issue.
http://commune-bourre.com/userfiles/crimestopper-sp-500-manual.xml

But if I sat intently in front of a sound system listening, listened via earbuds or simply had the volume up at medium to higher levels, as songs faded out there was a background noise that was not there on the original program material. The Transmitter 2 looks identical to the original model except for the name printed on the front. It has all the features of the original model and some new ones: PLL design, push button tuning, LED frequency readout (now with a battery indicator added), volume control, LED modulation level indicator, auto shut-off feature, the ability to run from two AA cells or the included AC adapter, and a mini-plug input cable for easy connection to almost any device with a Line Out or headphone jack. By far the biggest improvement: THE NOISE IS GONE. Of course, no audio component is 100 noise free. Noise is now so low that you should never detect it in normal use. I measured a signal to noise ratio improvement of over 10 DB compared with my original model and that is a huge improvement. In essence you will now have dead quiet backgrounds even with demanding program material played back at high volume levels. The LED Volume (modulation) indicator also gives a clue to another big improvement. The new version has a green LED which flashes on normal modulation levels but abruptly flashes a bright RED warning when you are pushing the audio levels too hard.Depending on the characteristics of the program material, as I approached maximum modulation I sometimes heard audio compression which kept the sound from going into over-modulation. The old model would easily over-modulate producing gross distortion through your radio if you didn’t adjust the level properly, while the new model limits itself. This is desirable but don’t push the volume level too hard or you will hear that pumping sound. When setting your audio input level, listen carefully and try a few different songs or audio types.
https://www.airyachtnboat.com/en/article/elite-k7s5a-manual

Be sure the LED indicator stops flashing red except very occasionally and you should be OK, but then listen for sounds of compression in the audio.The reason is that most stations use very expensive, sophisticated audio processing equipment which maximizes loudness, often at the expense of naturalness, while still preventing over-modulation. In other words, this is normal. It also remembers the last set frequency if AC power is interrupted. Finally, the Sleep Timer (auto shut off) now offers choices ranging from 8 hours down to 1 hour versus the single choice of 1 hour on the original model. I know of no other home FM Transmitter that can match the C.Crane FM Transmitter 2 for excellent sound quality and now low background noise. In fact, this is another unique C.Crane product as I am not aware of any other FM Transmitter anywhere near this price level that performs as well, is as versatile and easy to set up and use even for non-technical users. I have been enjoying the C.Crane FM Transmitter for several years and starting today, I’m enjoying it even more. Highly recommended! Email me at.

I do believe there's some lessons as far as how to properly use this product though that would ensure success. First, the gain mod is easy, took me roughly 5 minutes. Be careful prying off the rubber feet over the two case screws, the 3rd screw is in the battery compartment.
http://experience-hr.com/images/canon-xt-owner-s-manual.pdf

You'll need a small fine point Phillips screwdriver to do this - and be gentle with the gain screw, turning CCW gently to full. Next, my rig. First, I live in a single level home, so I centrally located the unit, placed on my fridge (get it as high as possible). I use the AC adapter, and I use my laptop for a source as opposed to my phone. For me, it keeps background FM hiss to a minimum in comparison to my phone and tablet. You will have to adjust both the source volume as well as the input on the unit to the highest level where the peak LED stays in the green so you will not clip your sound. This will take some time to find the sweet spot, and expect to use your amplifier volume a bit higher than normal. Lastly, I know most people nowadays won't be able to do this, but for me it worked best. When searching for a frequency in your area, go to and plug in your zip code. For me, I had both 89.9 and 90.1 available. However, I have old school analog tuners that can tune into any FM frequency. So I set the FM2 to 90.0 - which seems to work much better than 89.9 or 90.1. There's no broadcast station in the US that uses 90.0.so it seems that at least for me, I get the most quiet tuning capability doing exactly that - with practically zero hiss or adjacent station artifacts. For those that don't have an analog tuner, look for 3 in succession (for example 89.9, 90.1 and 90.3 - pick the middle freq). Anyway, this is what worked best for me. My 3 stereo rigs are roughly 20 to 30 feet away from the unit, and the sound quality is for what we're actually doing here, excellent.Works no better than the brand that my wife bought at Five Below: sporadically or not at all. I bought it to stream music to the Dolby sound system of my '95 BMW. When it does work it sounds like the AM radio in my Dad's '55 Chevy. Please try again later.It does exactly what it says it will (with the gain hack as described elsewhere).

Frank in MN 5.0 out of 5 stars They can individually dial in their own volume level suitable for them, while we do not get driven out of the area by the TV blasting away (which is the case when using just their hearing aids, alone.) This is also a great solution when one person wants to read while another wants to watch TV in the same room. The TV watcher listens through the headset, while the built-in TV speaker volume is muted so the reader can do so in a silent room. A win-win situation!Please try again later. Please try again later. Dan The Man 5.0 out of 5 stars I've used other transmitters that worked O.K. on batteries but I needed one that delivered fine sound using 120v AC as the power source. I'd skipped over this product in the past due to the price. After experimenting with various other solutions, I now wish I had just gone with this item to begin with. The FM2 sounds great either on battery or AC. Out of the box the range is awful. I performed the so-called 'mod,' which is nothing more than opening the case, adjusting a small dial with a screwdriver, and closing the case. Very simple and also reversible. Now the range is incredible. A feature I'm impressed with is the volume control which allows you to adjust the incoming audio level so it won't overload the transmitter and distort the sound. A LED changes color from green to red to indicate an overload. Also you can use any of the frequencies available in the entire FM band. Very useful for large cities with lots of FM stations. An adapter is included with left and right RCA plugs so no need to purchase that separately. Also included is an AC adapter.Please try again later. Please try again later. Southplank 4.

0 out of 5 stars I thought people were exaggerating the poor performance, but I was only getting at best 15 feet line of site. I cranked the power up, it is better, but still does not meet my needs, the signal is quite weak and requires careful positioning of the receiving radio's antenna. My goal was to listen to internet talk radio (via speaker) while working around the yard and garage. Currently I bring my Kindle Fire along with volume maxed out. I will continue to do that as my wifi signal reaches much further than this device. Maybe I'll get a small external speaker. Using my portable radio with antenna fully extended and needing to tweak the exact position is much more cumbersome than carrying the kindle from chore to chore. Within it's short range, the sound is quite good. This could work in certain situations where you won't be moving around with the radio. The signal is just too weak and you will get noise as you move around. I could see it working if you have internet or satellite radio and need to set up some receivers in various rooms around your home or office. Position the antennas and then leave them be. The idea is good, but the FCC won't allow it to function at a useful power level and some may not be comfortable opening the device up. Update. I did return this device since it did not work well for me at all. Fast forward several months. My old wireless headphones that I sometimes watch TV with weren't doing it for me. Too big and bulky. So I tucked my tail between my legs and ordered another of these transmitters. While still useless for my original purpose of working around the yard listening to internet radio, it works pretty well for watching TV and listening on a small pocket radio with earbuds. I did extend the antenna with a short piece of wire. I can move about the house with my pocket radio and earbuds. Works decent for this purpose even with the power adjustment at its original position.
{-Variable.fc_1_url-

Extending the antenna may be an option for someone not wanting to tamper with the internal setting. I eventually did crank up the power as well for more solid performance. Update 2. After some experimenting, I found with the power cranked up and locating the extended antenna wire inconspicuously in a window frame, I can now listen to internet radio outside if I am fairly close to the house. I still can't walk around with the radio, but if I set up my large portable up and adjust the antenna, it works. Sound quality is very good. For a tuner, I am using an old smart phone which has no cell service but runs radio apps fine on wifi. I'm upping my rating from 2 stars to 4 stars. A tip to improve empty channel selection: Step outside with your radio receiver and turn the volume up when looking for empty frequencies. Reception is generally better outdoors, so it will be easier to find the most quiet frequencies. Also try to find three consecutive unused frequencies and choose the middle one.Please try again later. Please try again later. Martin Stevenson 5.0 out of 5 stars I bought the prior version of this 11 years ago. It gave very good service but the antenna mounting broke a couple of years ago. This caused the transmitter's power to drop unacceptably until I re-wired its connection to the electronics. The new mounting looks roughly as mechanically vulnerable to falls with the antenna fully extended. However, it appears that the connection to the electronics will not be broken even if the mounting does break. I am protecting the vulnerable mounting by boosting the transmitter's power but leaving the antenna collapsed against the transmitter's body. This appears to make it powerful enough to work without having to change frequencies while driving around the SF Bay area. The power adjustment is obvious as soon as you take the transmitter's back off. The quality of the electronic design of the new transmitter appears to be excellent.

It gives many hours of service on a single charge of rechargeable batteries The soft hum that was present in the older design is completely gone. The unit responds to the press of the on button much more quickly. This makes it much easier to engage the timed operation. The battery level indicator is a welcome new feature.Please try again later. Please try again later. Mr47 4.0 out of 5 stars All you have to do is peal the sticker off of the back and you will see a small hole at the top, just stick a small flat head screwdriver in it and turn the pot all the way counter clockwise if I remember right and you are all set. Very good sound quality. Its not quite as good as a local radio station, but it is darn close. It sounds good enough that I don't feel the need to replace my factory radio in my grand prix just yet (which turns out be very expensive because of a special wiring harness I need). There are only two things in my eyes that keep this transmitter from greatness: 1) No signal sensing auto on. My old twenty dollar transmitter had this feature, which allowed me to hide it in my car and just run a cable to it. All you had to do was turn on your mp3 player or Ipod and it would turn on once it sensed music. This feature is not a real big deal to me, but it would have been nice. 2) That darn curly input cable. I didn't think it was going to be that big of a deal to me, but it turns out it really is. It gets caught on everything, and for the OCD out there, you never can keep the curly part in line with itself. It is also very thin, and considering I payed about 50 bucks for this thing, I expected a much MUCH better quality cable (I personally guarantee it will be the first thing to fail on this transmitter). I would have preferred a good old fashion stereo plug so I could use my own male-male stereo cable instead. If they fix this problem in another update, it would be worth the full five stars.Please try again later. Please try again later. Ken C 4.

0 out of 5 stars There's plenty of info on how to open the case and turn the adjustment screw to increase the range from dismal to monster. Just make sure you get the current info since the newest info will instruct you to turn the screw counter-clockwise to increase transmit power (unlike earlier instructions) Out of the box the FM2 transmitter couldn't reach my portable FM radio at 10 feet on a clear channel. At full power, it was able to reach almost 100 feet. Do buy this, just know that a 2 minute tweaking will be needed to get it usable.Please try again later. Please try again later. lazd 4.0 out of 5 stars However, I live in a modern high-rise in a major metropolitan area, and this unit won't make it into the next room without an unsatisfactory level of static. Yes, I opened it up and turned the VR2 potentiometer until the output increased. I tried creating a ground plane by putting it on a metal tin. I moved the antenna on the transmitter and the receiver until I was traumatized by the sound of static. There is simply no way to achieve a full quieting signal between two rooms. I've thoroughly voided the warranty to the point of no return, so I won't be trying to RMA this little device. And I actually don't want to. It sounds good, the construction is decent enough, and when you don't have 3 steel-reinforced walls in between the source and the destination, it performs fairly well.Please try again later. Please try again later. Natick Franks 5.0 out of 5 stars Caution-Make sure to remove the three rear screws (two under rubber feet, one in battery case) and turn VR2 fully counterclockwise, then re-assemble. For some reason they ship these things set to minimum transmit power. Once you turn VR2 counterclockwise, there is plenty of range. The stereo audio quality is also very good. I was able to hide this little unit behind my TV and I can still receive it anywhere in our bedroom and down the hall.

This is great because my wife can now stay up and watch the Tonight Show while I sleep, so I can get up early in the morning.Please try again later. Please try again later. Bill G. 5.0 out of 5 stars I have Amazon Prime 2-day shipping but this came in 24 hours via USPS. I have an older Delphi XM Satellite receiver that has a built-in FM transmitter. It has rather weak output, though, and I was hoping I would be able to plug the C. Crane unit into it and get a good broadcast signal all through the house. Very easy - removing three small Phillips head screws opened the case and I just turned the pot adjustment with my fingernail (CCW). Now I have a good, strong signal all through the house. Before I had really spotty XM reception at my downstairs stereo receiver (The XM receiver is upstairs) but now it’s loud and clear. The boombox in the garage, about 50 feet away, is getting a great signal. I even took a portable radio outside and was getting reception more than 100 feet from the transmitter. If the C. Crane is reliable in the long run, I’m a happy customer!Please try again later. Please try again later. Perhaps you would like to play your favorite Internet radio station or MP3 files from your personal computer's (PC's) hard drive on your back porch. Maybe you want to hear the television audio in your garage. Or perhaps you would like to hear your Talking Book player through the car's sound system on your next trip.An FM radio transmitter can be connected to the audio-out or headphone jack of almost any device, including a PC sound card, Talking Book player, MP3 player, or tape recorder. The audio is transmitted to any nearby FM radio receiver, such as the car radio, a Walkman radio, or your stereo receiver. Note, however, that the range of a low-power, license-free FM transmitter is limited, so you will not be able to transmit from your home and receive the signal miles away while you walk around town.

Nevertheless, many people who are visually impaired find limited-range portability of audio material to be convenient in their homes. In fact, these transmitters have been discussed extensively on the PC-Audio e-mail group. (To subscribe to the list, send a blank e-mail message to.) Two other transmitters are discussed for readers who want to explore the topic further. These units cover a range of price points and capabilities. The transmitter must be tuned to a frequency on the FM radio band that is not in use in your area of the country. Finally, volume levels on the source or transmitter must be adjusted to provide an audio signal that is strong enough, yet not so loud that it overdrives the transmitter. A signal that is too loud will generate distortion of the audio as it is transmitted. After you finish these setup steps, your audio program is broadcast like any other radio station to a nearby FM radio receiver. Finally, the radio receiver you will be using needs to be tuned to the frequency that you selected when you set up your transmitter. It can also be used indoors with television, video games, keyboards, or computers. A telescoping 3A?-inch antenna is built into the top right of the case. Also on the top is a slide switch for power. Moving this switch to the right toward the antenna turns the unit on. At the top of the left side is the jack for the audio-input cable. Below this jack is a tuning knob that is used to select the SF120's transmit frequency. Below the tuning knob is a three-position switch that is used to select the portion of the 88-108 MHz FM band to be used. This frequency-range switch basically divides the FM band into thirds, allowing the frequency-tuning knob to offer finer tuning than would be possible if it were covering the entire range in one rotation. The battery compartment is located near the bottom of the back of the unit. It is opened by sliding the compartment's cover to the left.

Operating the unit is fairly simple; all you need to do is to find an unused frequency on an FM radio, connect the SF120 to an audio source, turn it on, and tune the SF120 until you hear your audio source in the radio. There is no audio-level adjustment on the SF120, so the volume control on your audio source is used to control the transmitted audio volume. However, the transmission range on the unit I evaluated was limited. The unit worked well transmitting to a car radio from anywhere within the car, so it was excellent for sharing Talking Books or the contents of an MP3 player with others on a road trip. But I found that the limited range made it impractical for transmitting farther than within one room at home. The audio cable that was provided was short, so that the SF120 had to be within a foot of the source. Also, tuning the transmit frequency was a bit of a problem. Although it was easy to accomplish without sighted assistance, even a slight movement of the tuning dial caused a fairly large movement in the frequency. Even after I set the transmitter on the open frequency I chose on my FM radio, it was easy to accidentally bump the transmitter frequency control and have to retune. Plug it into the headphone jack of your computer's speakers or sound card and listen on any FM radio anywhere in the house. The FMT does so by taking the audio and turning it into an FM radio broadcast. It has an approximate line-of-sight range of 70 feet. Walls and metal objects will reduce this range. The case has rubber feet on both the back and the bottom sides, so it can be positioned flat or vertically on a desk or shelf. A telescoping 11-inch antenna is located on the top left of the unit. In addition to telescoping, this antenna has a swivel base, so that it can be adjusted to a vertical position, regardless of how the FMT is oriented. It is a wide oval-shaped button. Pressing it quickly turns the unit on.

If the button is held down for more than a few seconds, it activates an automatic power-off feature. The FMT cycles through 1-, 2-, 4-, or 8-hour timer choices. To the right of the power button is a small red LED (light-emitting diode) that indicates that the input audio is too loud. Below the power button is a digital frequency display. To the lower right of this display are two buttons that are situated on a diagonal. The upper right of these two buttons increases the broadcast frequency, and the bottom one lowers the frequency. Each time these buttons are pushed, the frequency changes by 0.05 MHz. There is a transmit-volume control on the right side of the case. The built-in audio cable is attached on the lower left side of the case; it is a coiled cord that can be extended to about three feet. Below this cable is the jack for the included 110V power adaptor. The battery compartment is on the lower half of the back of the unit; the cover slides off to the left to allow the installation of two AA batteries. The frequency can be set by pushing the frequency-increase buttons while listening for the signal on your FM radio tuned to an unused frequency. The transmit-audio level can be set by ear, again listening to the volume and quality of the signal in the radio. Once set, it is not easily bumped off the selected frequency. The stereo audio quality is excellent, and the range is good. The manual states that a range of 70 feet in an unobstructed area should be expected. I did not attain this range, but I was using the FMT in my home, so the signal was obstructed by walls and electrical systems. The included 110V power adapter is a handy feature when you use the FMT in a fixed location, such as when it is connected to a computer's sound board output. The power button was probably pressed by something while in transit. Without a radio to hear the signal, there is no way for a blind user to know if the FMT is on or off.

Although I have not evaluated either of them, these transmitters from Veronica and from Ramsey Electronics have been discussed extensively by contributors on the PC-audio e-mail group. Veronica is a European provider of transmitters in both kit and assembled versions for professional applications. Many of its products exceed the U.S. power limits for license-free operation (see Veronica's home page at ). Ramsey Electronics offers several AM and FM transmitters (see its home page at ). Note that the Ramsey Electronics transmitters and some Veronica models are kits that require assembly by someone who is experienced in building electronic kits. The FM transmitters that have been discussed in this article fall under these regulations. Anyone who operates such a device is responsible for understanding and complying with the appropriate regulations. A good introductory discussion of the FCC rules regarding low-power, license-free FM broadcasting can be found on the Ramsey Electronics web site at. If you buy a kit that requires adjustment to comply with regulations or a device that is not designed to be used in the United States, you are still responsible for operating it in compliance with the FCC rules. Your support is vital. I use it as a poor man’s Sonos: I broadcast music and podcasts from my computer to any radio in the house. I am not limited in the devices I use to hear the broadcast; I use a few Boston Acoustics Solo tabletop radios, but any radio would work, even a walkman-type device. Setup is fool-proof; just tune the radio to the proper frequency. Other people use it to watch movies without disturbing other people in the room. They just use an FM radio like the one in many iPods, and earbuds. Musicians use them for stage performance. Etc. This one stands out in a few ways. It has excellent audio quality, as good as you can get with FM. That is especially apparent in the bass frequencies.
