Press and hold the Lock button until the light blinks (about

four blinks and 4-1/2 minutes.

the motor unit panel is activated.

To Open the Door Manually

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.
The door should be fully closed
if possible. Pull down on the
emergency release handle and lift the
door manually. To reconnect the door
to the opener, press the door control
push bar.
The lockout feature prevents
the trolley from reconnecting
automatically. Pull the emergency
release handle down and back
(toward the opener). The door can
then be raised and lowered manually
as often as necessary. To disengage
the lockout feature, pull the handle
straight down. The trolley will
reconnect on the next UP or DOWN
operation, either manually or by using
the door control or remote.
