How to Program a Bluetooth With a Phonak FM Transmitter

Phonak, a Swiss company that specializes in hearing aids, makes several FM transmitters that transmit sounds from a source to a hearing aid, giving the listener clear and dynamic sound. The SmartLink+ FM transmitter features audio zoom settings to control the source and intensity of incoming audio as well as audio inputs for wireless TV. It also features Bluetooth support, which is a wireless protocol for sending and receiving data and most commonly used to connect cell phones to wireless headsets. Bluetooth allows you to connect your cell phone to the FM transmitter to make phone calls through your hearing aid.


  1. Turn on your cell phone and SmartLink+ FM transmitter.

  2. Press and hold the green "Phone" button on the SmartLink+ for five seconds until the screen starts to flash.

  3. Navigate to the Bluetooth menu on your phone and select "Search" or "Add Device" to add a new Bluetooth device. Every phone has a different process, so refer to your phone's user guide for specific instructions on how to add a new device.

  4. Select "SmartLink+" from the list of available Bluetooth devices on your phone.

  5. Enter "0000" as the device password if you are prompted to by your phone to complete the pairing process.

How to Build an FM Transmitter Antenna

Portable satellite receivers let you listen to music through your car's FM radio by using a built-in FM transmitter. You can make an FM transmitter antenna, which will amplify and boost the FM transmission capabilities of the satellite radio's FM transmitter. This will provide a better signal for hearing the music being transmitted. You will need a few parts from an electronics supply shop and expertise in using a heat gun and soldering iron. The satellite radio must have a plug to accept an FM transmitter antenna or the antenna cannot be used.


Things You'll Need:

  • 2.5mm phone plug
  • Copper wire spool
  • Wire strippers
  • Wire cutters
  • Heat shrink tubing
  • Utility knife
  • Soldering iron
  • Solder
  • Heat gun
  1. Unscrew the back off the phone plug. Unwind some copper wire from the copper wire spool. Strip a half inch of insulation off the end of the copper wire with the wire strippers.

  2. Push the end of the copper wire through the hole in the bottom of the back of the phone plug.

  3. Heat up the soldering iron for two minutes. Solder the end of the copper wire to the inside metal lug attached to the phone plug. Let the solder cool for a minute.

  4. Cut a piece of heat shrink tubing that is about the same length of the metal lug with the utility knife.

  5. Put the piece of heat shrink tubing over the metal lug. Hold the heat gun over the heat shrink tubing. Turn on the heat gun.

  6. Turn off the heat gun after a minute has gone by.

  7. Screw the back of the phone plug back onto the phone plug.

  8. Measure two feet of copper wire from the back of the phone plug. Cut the copper wire from the copper wire spool at the two-foot mark with the wire cutters.

  9. Plug the phone plug into the phone plug connection on the portable satellite radio.

How to Place an FM Transmitter for a Radio Station

Appropriately placing your FM transmitter for your radio station is perhaps one of the most important technical things you do. The placement of your FM transmitter determines who your audience is and how far-reaching your signal is.


  1. Read the instructions you are given by the FCC carefully to determine the scope of how strong of a signal you are allowed to have and which regions you are not allowed to interfere with.

  2. Determine who you want to have in your audience. Typically radio stations want to include as many people as possible in their audience within the municipalities that they want to reach.

  3. Map your primary and secondary audiences. When you place a transmitter, depending on the signal strength, you will have a primary audience and a secondary audience. The primary audience includes the areas that will most strongly pick up your signal. The secondary audience includes the areas that will pick up the signal more weakly.

  4. Locate the center of where you want your primary audience to be. It might be in the middle of a cornfield somewhere, or it might be in the center of the city. You want to find the median location of where your primary audience is situated.

  5. Drive around in the locations where you would like to place your FM transmitter. Look to see if there are towers already in place or whether you would have to build one yourself.

  6. Contact the owners of the towers in the areas you are considering for your FM transmitter. Find out how much it would cost for you to rent space on their towers. Compare the costs and the benefits of having your transmitter in each particular location.

  7. Mount your FM transmitter on the tower you selected.
