Any unauthorized modification to this device could void the user's authority to operate the equipment. Programming or reprogramming the integrated remote control Step 1: Switch on ignition. Step 2: If you have previously programmed an integrated signal transmitter button and wish to retain its programming, proceed to step 3. Otherwise, press and hold the two outer signal transmitter buttons 2 and 4 and release them only when the indicator light begins to flash after approximately 20 seconds (do not hold the button for longer than 30 seconds). This procedure erases any previous settings for all three channels and initializes the memory. If you later wish to program a second and/or third hand-held transmitter to the remaining two signal transmitter buttons, do not repeat this step and begin directly with step 3. 232
