keyless entry you wish to use.

Model 372LM Security✚®2-Button Remote Control

The 372LM remote control can activate two separate

315MHz 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.

Both push buttons are factory programmed to work with

315MHz Security✚®receivers having a purple “learn”

button. The rolling code between these buttons and 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.
