Using your Garage Door Opener

The garage door opener can be activated with a wall-mounted door control, remote control, wireless keyless
l
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.
