Using your Garage Door Opener

The garage door opener can be activated through a wall-mounted door control, remote control, wireless keyless
entry or myQ® App.
When the door is closed and the garage door opener is activated the door will open. If the door makes contact
with an obstruction while opening, the door will stop, opener beeps and lights flash 5 times. 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 makes contact with an obstruction while closing, the door will reverse, opener beeps and lights flash 5
times. However, you can close the door if you hold the button on the door control or keyless entry until the door
is fully closed.
The safety reversing sensors do not affect the opening cycle. The safety reversing sensor must be connected and
aligned correctly before the garage door opener will move in the down direction.
IMPORTANT SAFETY INSTRUCTIONS
