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

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

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 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 35.

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.

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.
