Operation
Using your Garage Door Opener
l The garage door opener can be activated with a wall-mounted door control, remote control, wireless
keyless entry, MyQ
®
Smartphone Control app or MyQ
®
Garage Door Monitor. When 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
®
Smartphone Control app. 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.
l The garage door opener light bulbs will turn on when the opener is initially plugged in; power 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 36. Use an incandescent A19 light bulb (100W
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:
l 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.
l NEVER use emergency release handle unless garage doorway is clear of persons and obstructions.
l NEVER use handle to pull door open or closed. If rope knot becomes untied, you could fall.

1. The door should be fully closed if possible.
2. Disengage the automatic garage door lock by sliding the manual release to the
open position.
3. Pull the emergency release handle down and back (toward the garage door
opener). The garage door can then be raised and lowered manually as
necessary.
4. To reconnect the trolley, pull the emergency release handle straight down. The
trolley will reconnect on the next UP or DOWN operation.
NOTE: The automatic garage door lock will re-engage when garage door opener
operation resumes.
