Chamberlain 377LM User Manual

FEATURES

For use with any 315 MHz SECURITY✚®garage door openers
having a purple “learn” button.

Personalized Password: Up to 10,000 possible combinations.
Password can be easily changed if desired.

Temporary Password: Can be added for visitors or service
persons. This temporary password can be limited to a
programmable number of hours or a programmable number of
entries.

Rolling Code: While your password remains constant until you
change it, the code between the Keyless Entry and the receiver
changes with each use, randomly accessing over 100 billion
new codes.

Operation: Opener activates when 4-digit password and
ENTER button is pressed.

If wrong numbers are accidentally pressed, correction can be
made immediately. The ENTER button will transmit only the last
four digits.

The keypad will blink for 15 seconds after the password is
transmitted. During that time the ENTER button can be used to
stop or reverse the door travel.

The Lock feature on openers with Multi-Function Door Controls
is designed to prevent operation of the door from portable
transmitters. However, the door will open and close from the
door control push button and the Keyless Entry.

One Button Close: Opener can be closed by pressing only the
ENTER button if the one button close feature has been
activated. This feature has been activated at the factory. To
activate or deactivate this feature press and hold buttons 1 and
9 for 10 seconds. The keypad will blink twice when the one
button close is active. The keypad will blink four times when one
button close is deactivated.

last temporary PIN), then press and hold the ✽ button.

The opener light will blink three times. Release the button.

2. Press the temporary 4-digit PIN you have chosen, then press
ENTER.

The opener light will blink four times.

press ENTER. The door should move. If the temporary PIN was
set to a certain number of openings, remember that the test has
used up one opening. To clear the temporary password, repeat
steps 1-3, setting the number of hours or times to 0 in step 3.

SPECIAL NOTE: The temporary password can ONLY be
programmed to Keyless Entries working on a 315 MHz
Chamberlain or LiftMaster Garage Door Opener. It WILL NOT
work on Keyless Entries programmed to an external receiver.

The temporary password will continue to CLOSE the door even
after the time has expired. To eliminate this, program a new
temporary password into the Keyless Entry.

the Keyless Entry illumination
becomes dim or it doesn’t stay on
after a keystroke.
