Chamberlain 974LM User Manual

Model 974LM Security✚ 4 Channel Remote Control

OWNER'S MANUAL

The 974LM remote control can activate four separate residential or commercial garage door openers and/or gate openers. The instructions for programming garage door openers are illustrated below. Please refer to the original receiver programming for commercial and gate products.

All four push buttons work with Security✚ receivers having an orange “learn” button. The rolling code between these channels and the receiver changes with each use, randomly accessing over 100 billion new codes.

As an added feature, the

4th

push button is capable of learning or being trained to duplicate or match another CGI manufactured fixed code or billion-code remote. This feature is normally used when several remotes are required to operate one fixed code device such as a gate opener or commercial dock door. In this case, the code transmitted to the receiver remains constant or fixed, not using the Security✚ format.

1.Press and release the “learn” button on the motor unit. The learn indicator light will glow steadily for 30 seconds.

2. Within 30 seconds, press and hold the button on the hand-held remote that you wish to operate your garage door.

3. Release the button when the motor unit lights blink. It has learned the code. If light bulbs are not installed, two clicks will be heard.

Instructions are described and illustrated below.

To deactivate any unwanted remote, first erase all codes: Press and the hold “learn” button on motor

unit until the learn indicator light goes out (approximately 6 seconds). All previous codes are now erased. Reprogram each remote or keyless entry you wish to use.
