Instruction Manual

Installation
1. Before you begin
Your garage door opener has an internal gateway located on the receiver logic
board. After installing the new receiver logic board, use the myQ® serial
number found on the provided label to add your garage door opener to your myQ®
account. The products illustrated in the instructions are for reference. Your
product may look different. The logic board firmware has been updated. The
update provides a new Obstruction Notification that signals when the opener
senses resistance, such as an obstruction or other binding in the door and
rail system. The door will stop or reverse to the open limit and the opener
will beep and the lights flash 5 times.
WARNING
To prevent possible SERIOUS INJURY or DEATH:
- Disconnect ALL electric and battery power BEFORE performing ANY service or maintenance.
CAUTION
To prevent damage to the receiver/logic board, DO NOT touch the printed
circuit board of the replacement receiver/logic board during installation.
ALWAYS wear protective gloves and eye protection when changing the battery or
working around the battery compartment.

Adjustment
1. Program the travel
WARNING
Without a properly installed safety reversal system, persons (particularly
small children) could be SERIOUSLY INJURED or KILLED by a closing garage door.
- Incorrect adjustment of garage door travel limits will interfere with the proper operation of the safety reversal system.
- After ANY adjustments are made, the safety reversal system MUST be tested. The door MUST reverse on contact with a 1-1/2″ (3.8 cm) high object (or 2×4 laid flat) on the floor
While programming the travel, the UP and DOWN buttons can be used to move the door as needed. The Safety Reversing Sensors will be disconnected during the Program the Travel process. During the Automatic Force Setup, the door will automatically open and close.
| 1.1 Press and hold the Adjustment Button
until the UP Button begins to flash and/ or a beep is heard.
The Safety Reversing Sensors will be disconnected during the Program the
Travel process.

position press and release the Adjustment Button. The garage door
opener lights will flash twice and the DOWN Button will begin to flash.

the door is in the desired DOWN position.
| 1.5 Once the door is in the desired DOWN
position press and release the Adjustment Button. The garage door opener
lights will flash twice. Program the Travel is now complete. If the garage
door opener lights flash 5 times, then programming has timed out and the
Travel Limits have not been set. Please restart the Program and the Travel
process.

2. Automatic Force Set Up
Once both the up and down positions have been manually set, the Safety
Reversing Sensors will reconnect and become operational. Then, the opener will
enter a force-sensing operation by automatically moving the door open and
close. The garage door opener will sound an audible and visual alert before
automatically opening and closing the door. The garage door opener will beep
three times, confirming that the Automatic Force Setup was completed
successfully. Adjustment is complete.
If you hear one long beep after the door attempts to move, then the Automatic
Force Set-Up has not been completed successfully. Please start over at step 1
of Program the Travel.
3. Test the Safety Reversal System

either safety reversing sensor is off (alerting you to the fact that the
sensor is misaligned or obstructed).
If the garage door opener closes the door when the safety reversing sensor is
obstructed (and the sensors are no more than 6 inches [15 cm] above the
floor), call for a trained door systems technician.
