Chamberlain LiftMaster PROFESSIONAL 423-315LM Owner's Manual

The receiver can be used with a 3-Button control station to OPEN,
CLOSE or STOP a commercial door operator or gate operator. This
product is not for use with residential garage door operators.
NOTE: This product is only for use in the United States, Latin America
and Mexico.
INSTALLATION
The receiver and antenna use TV Type F coaxial connectors. The antenna
can be plugged directly onto the receiver or mounted to a bracket and
connected to the receiver with Model 86 Coaxial Cable Kit, depending on
your requirements.
Select a location for the receiver which allows access to the terminals and
space for the antenna (as far from metal structures as possible and
preferably with the antenna in an upright position). Fasten the receiver
securely with screws through the two holes provided in the cover flanges.
TO USE THE RECEIVER WITH A 3-BUTTON CONTROL
STATION AND A COMMERCIAL DOOR OPERATOR:
Consult your manufacturer's control connection diagram for instructions
on connecting two or more 3-button control devices (Figure 1).
• Use a screwdriver to pry open the receiver cover.
NOTE: The slide switch is factory set to the N.C. position (otherwise the
operator will not operate). Verify this setting. Re-connect power to the
operator and the accessory transformer, if used.
• Select a remote control button to STOP the operator.
• Press and hold the selected remote control button.
• Then press and release the "learn" button labeled "A" on the receiver.
The adjacent indicator light will FLASH.
• Release the remote control button.
Repeat the procedure above with a second remote control button and
receiver "learn" button "B" to program the OPEN operation; and again
with the last remote control button and receiver "learn" button "C" to
program the CLOSE function of the operator.
Return the front cover to the receiver.
NOTE: If a remote control button is not pressed within 30 seconds, the
indicator light adjacent to the selected "learn" button will turn OFF.
In that case, repeat the programming.

OWNER'S MANUAL
To prevent possible SERIOUS INJURY or DEATH from electrocution:
• Be sure power is not connected BEFORE installing the receiver.
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 control 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.
To prevent possible SERIOUS INJURY or DEATH, the use of
CONSTANT OPERATION on residential operators is PROHIBITED.
When a receiver is used to activate a commercial door operator, a
reversing edge MUST be installed on the bottom of the door. Failure
to install a reversing edge under these circumstances may result in
SERIOUS INJURY or DEATH to persons trapped beneath the door.
