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.
