Headphones keep shutting off


There's an auto-shutoff feature which kicks in when the audio input to the transmitter is too low. That's usually indicated by the green light on the transmitter turning off. Just increase the volume on the device connected to the transmitter, and you should see the green light come back on. As long as that's on, it'll stay transmitting and shouldn't just shut off.

How do i program my car to open the door? i have built into my new car. everytime i try to program it, it will not work. what am i doing wrong?


  1. Clear out anything previously programmed into the in-car system from the factory by holding down on the 2-outside buttons simultaneously, until the in-car LED starts flashing rapidly. This may take up to a minute (in most cases, the key should be on auxilary, and/or the car door must be shut).

  2. Decide which button you want to make to be your in-car garage door transmitter. Hold your transmitter up near the selected button, pressing both the garage door remote and the selected in-car transmitter button simultaneously. Hold down on the buttons until the in-car, LED light flashes rapidly. This sets the in-car remote transmitter to be your garage door openers make transmitter, but you are not done. You now need to make this in-car transmitter your personal transmitter.

3. Go to the Learn Button on your garage door opener. The button is usually next to the area where the floppy antenna is connected to the motor head. With Genie it is most often behind the light lens, and an indicator light flashes red when pressed. With Sears or Liftmaster (Chamberlain) it is near, or part of, the terminal screw board, and is a red, green or purple square button with a green, amber or purple indicator light. Press this learn button momentarily. The indicator light will turn on and blink if Genie or otherwise stay lit. For Genie systems, go back to the in-car transmitter button you programmed and press this button 3 or 4 times, or until the door starts moving. This should set your in-car transmitter to your garage door opener. For Liftmaster, Sears, or Linear Megacode press and hold the in-car button you programmed until the garage opener light flashes. Your in-car is now programmed to operate your door.

Quantum 3213. the door opener opens neighbors and visa versa


You can follow these instructions to change the code of yours. Might work for you.

NOTE: You must change the transmitter's code before programming the transmitter to the motor head unit.
The following steps describe the process to change a Quantum™ and Classicdrive™ security code.
This process only works fro transmitters with a GREEN LED and a "U" in their model number, such as "02-3047 2B U" or "02-3047 2B UH".
Changing the Transmitter Code
1. Press and hold the button on the transmitter that you want to change. The GREEN LED will flash once and then turn off.
2. Continue to hold the button until the GREEN LED begins to flash (approx. 10 seconds).
3. When the GREEN LED flashes, immediately release the button and then immediately press and hold the same button again. The GREEN LED will now come on steady.
4. Continue to hold the button until the GREEN LED begins to flash (approx. 5 seconds).
5. When the GREEN LED flashes, immediately release the button.
6. The code for this button has now been changed to a new randomly generated code. Do not push the button again until instructed in "Programming Transmitter to Power Head Unit".
7. You must now re-program this transmitter to the motor head unit. See "Programming Transmitter to Power Head Unit".
Programming Transmitter to Power Head Unit
1. Press the PROGRAM button located on the garage door motor head unit once. The PROGRAM STATUS light on the motor head unit will turn on and remain lit for one minute, indicating that it is ready to learn the Transmitter code.
2. Press the same button on transmitter as you did in "Changing Transmitter's Code" above. The PROGRAM STATUS light will turn off indicating a successful learn.
3. Press the same button on the Transmitter once more to operate the door.
4. If you are unsuccessful in programming the transmitter to the motor head unit of if the button does not operate the door or if you wish to program another button to operate a different door, you must change the transmitter's code.
Battery
If the LED does not turn on when button is pressed, replace battery.

No sound from rear speakers on the lifestyle 18


The SL2 works in such a way that the speaker satellite out put from the bass modules is fed to the input of the SL2 transmitter (remember, transmitter) then the sattellitespeakers are connected at the other end of the room to the receiver. An initial blinking green light should be seen and once the system is turned on this turns into steady green. Both the SL2 transmitter and receiver operates via WIFI.

Glad to be of service...
