To control the opener lights:
In addition to operating the door, you
may program the remote to operate
the lights.
1. With the door closed, press and hold a small remote
button that you want to control the light.

To Open the Door Manually
DISCONNECT THE TROLLEY:
The door should be fully closed if
possible. Pull down on the
emergency release handle (so
that the trolley release arm snaps
into a vertical position) and lift the
door manually. The lockout feature
prevents the trolley from
reconnecting automatically, and
the door can be raised and
lowered manually as often as
necessary.
TO RE-CONNECT THE
TROLLEY:
Pull the emergency release
handle toward the opener at an
angle so that the trolley release
arm is horizontal. The trolley will
reconnect on the next UP or
DOWN operation, either
manually or by using the door
control or remote.
To prevent possible SERIOUS INJURY or DEATH from a falling
garage door:
If possible, use emergency release handle to disengage
trolley ONLY when garage door is CLOSED. Weak or broken
springs or unbalanced door could result in an open door
falling rapidly and/or unexpectedly.
NEVER use emergency release handle unless garage
doorway is clear of persons and obstructions.
NEVER use handle to pull door open or closed. If rope knot
becomes untied, you could fall.
