Operation

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 ® accessory.
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. 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.
