Chamberlain Lift-Master 68LM Manual

NOTE: To ensure the proper functioning of your new
Garage Door Opener, remove all old or previous push
buttons/wall control panels. Use only the enclosed
door control for proper operation.
Locate the door control within sight of the door at a
minimum height of 5 feet where small children cannot
reach, and away from all moving parts of the door and
door hardware.
The multi-function door control panel is typically attached
directly to the wall (Figure 1). For pre-wired installations (as
in new home construction) it can be mounted to a standard
single gang box (Figure 2).
• Strip 1/4" of insulation from one end of the bell wire;
connect the wire to the two screw terminals on the back of
the door control panel as follows: white to 2 and
white/red to 1. (NOTE: If "Lock" and "Light" buttons
do not function after completing installation, reverse
the connections.)
• For standard wall mount, fasten the door control panel
securely with 6ABx1-1/4" self-tapping screws. Run the
bell wire up the wall and across the ceiling to the opener.
Use insulated staples to secure the wire in several places.
Be careful not to pierce the wire with a staple, thereby
resulting in a short.
• For pre-wired installations, mount the door control to the
gang box with the 6-32x1" machine screws provided.
• Connect the bell wire to the opener terminal screws as
follows: white to 2 and white/red to 1.
