Coding Transmitters

Storing the Transmitter Code

The opener can only operate from transmitters that have been programmed into its receiver. The receiver needs to learn the codes of any transmitter that will be used with the operator. Up to eight (8) codes can be stored in the receiver’s memory.

a. Press the DOOR CODE button and release. The DOOR CODE LED will illuminate to indicate the opener is in Code Learn mode. If a valid code is not stored within 15 seconds the opener will exit Code Learn (Fig. 27).
b. Press the transmitter button (one of four) that you want to control the door. The DOOR CODE LED will begin to flash.
c. Press the same transmitter button again. The DOOR CODE LED will illuminate for one second and then go out.
d. The transmitter is now coded to operate the door – press the button to test.

Setting the Transmitter to Operate the Courtesy Light

Although the courtesy light comes on with each operation of the opener, it may also be controlled by a transmitter without operating the door.

a. Press the DOOR CODE button twice. The DOOR CODE LED will illuminate and the courtesy light will turn on to indicate that the light code learning is active (Fig. 28).
b. Choose a transmitter button not already coded into the receiver. Press this button and the DOOR CODE LED will begin to flash.
c. Press the same transmitter button again. The DOOR CODE LED will illuminate for one second and then go out.
d. The transmitter is now coded to operate the light – press the button to test.
