LiftMaster garage door opener 372LM remote control program installation instruction

Garage door opener remote control 372LM

The 372 remote control can activate two separate 315MHz residential or commercial garage door openers and/or gate openers.

Programming instructions are described below. Please refer to the original receiver programming for commercial and gate products.

Both push buttons are factory programmed to work with 315MHz Security+ receivers having an purple  “learn” button. The rolling code between these channels are the receiver changes with each use, randomly accessing over 100 billion new codes. 

As an added feature, the push button on the right 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.

NOTE: The push button on the left cannot be changed from Security+, only the right button is trainable.

*************   WARNING   *************

            Moving Door can cause serious injury or death.

·         DO NOT install transmitter unless the door operator’s safety reverse works as required by the door operator’s manual.

·         Wall control must be mounted in sight of door, at least 5 feet above floor and clear of moving door parts.

***************************************************************************************************************

Instructions are described below:

1. Press and release the “learn” button on the motor unit.  This can be found where you see the antenna wire hanging from the motor head (you may have to take the lens cover off). If antenna wire is not hanging from motor head then you have an external receiver which is a black box approx. 6" x 2" mounted somewhere in the garage with a antenna wire hanging from it (pop off cover to find Learn Code Button). 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 light blinks. It has learned the code. If light bulbs are not installed, two clicks will be heard.

To Erase All Codes From Motor Unit Memory

To deactivate any unwanted remote, first erase all codes:

Press and hold the “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.

When Several Remotes operate one device:

To match the 372LM to another CGI manufactured remote’s code (Remote Control X):

1. Begin by having both the 372LM and Remote Control X available.
2. Press and hold both buttons on the 972LM until the yellow indicator light, visible on the bottom through a small hole, begins to blink. It will blink for 30 seconds: during this time it is in the learn or training mode, and the buttons can be released.
3. While it is in learn mode, hold Remote Control X, another CGI fixed or billion-code transmitter, back to back with FCC labels touching.
4. Press and hold the Remote Control X push button as you slowly slide the remotes across each other until the 372LM indictor light blinks very rapidly, indicating it has learned the code. (If Remote Control X is also a 372LM, you must press and hold its right push button).
5. The right button is now sending the same identical coded signal as Remote Control X. This code will remain inside the 372LM until replaced with another new code by repeating steps 1-4 above, or by resetting to Security+.

Resetting the Right push button back to Security+ as follows:

Push and hold both buttons while observing the small yellow indicator light. Hold both buttons for ten seconds until the yellow indicator light stops blinking. The remote has defaulted to one of six randomly preprogrammed Security+ settings.

The Remote Control Batteries:

The Lithium batteries should produce power for up to 5 years. To replace, pry open case, insert batteries positive side up (+). Dispose of old batteries properly.
