WARNING

To prevent possible SERIOUS INJURY or DEATH from a moving gate or garage door:

•ALWAYS keep remote controls out of reach of children. NEVER permit children to operate, or play with remote con- trol transmitters.

•Activate gate or door ONLY when it can be seen clearly, is properly adjusted, and there are no obstructions to door travel.

•ALWAYS keep gate or garage door in sight until completely closed. Never permit anyone to cross path of moving gate or door.

NOTICE: To comply with FCC and or Industry Canada rules, adjustment or modifications of this receiver and/or transmitter are prohibited, except for changing the code setting or replacing the bat- tery. THERE ARE NO OTHER USER SERVICEABLE PARTS.

Tested to Comply with FCC Standards FOR HOME OR OFFICE USE. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.

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.

Instructions are described and illustrated below.

When Several Remotes operate one device:

To match the 974LM to another CGI manufactured remote’s code (Remote Control X):

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.
