the door is closed and the garage door opener is activated the door will open. If the door
senses an obstruction or is interrupted while opening the door will stop. When the door is in
any position other than closed and the garage door opener is activated the door will close. If
the garage door opener senses an obstruction while closing, the door will reverse. If the
obstruction interrupts the sensor beam the garage door opener lights will blink 10 times. If the
door is fully open, and the safety reversing sensors are not installed, or are misaligned, the
door will not close from a remote control, TTC, or the MyQ
However, you can close the door by holding the button on the door control or the ENTER
button on the keyless entry until the door is fully closed.
The garage door opener light bulbs will turn on when the opener is initially plugged in; power
l
is restored after interruption, or when the garage door opener is activated. The lights will turn
off automatically after 4-1/2 minutes. The lights will turn on when someone enters through the
open garage door and the safety reversing sensor infrared beam is obstructed, see page 35
(Motion Detecting Control Panel) or see page 37 (Multi-Function Control Panel). Use an
incandescent A19 light bulb (100 watt maximum) or for maximum energy efficiency a 26W
(100W equivalent) compact fluorescent light (CFL) bulb. NOTE: Do not use halogen, short
neck, or specialty light bulbs as these may overheat the end panel or light socket. Do not use
LED bulbs as they may reduce the range or performance of your remote controls.

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
l
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
l
obstructions.
NEVER use handle to pull door open or closed. If rope knot becomes untied, you could fall.
l
DISCONNECT THE TROLLEY
1. The door should be fully closed if possible.
2. Pull down on the emergency release handle so the trolley release arm snaps to the vertical
position. The door can now be raised and lowered as often as necessary.
TO RE-CONNECT THE TROLLEY
1. Pull the emergency release handle toward the garage door opener so the trolley release arm
snaps to the horizontal position. The trolley will reconnect on the next UP or DOWN operation,
either manually or by using the door control or remote control.
