2. Setup

2.1 Package Contents

Verify that your package contains the following items:

• LiftMaster 829LM Garage Door Monitor
• Power Adapter
• Instruction Manual (this document)

2.2 Device Placement

Place the monitor in a convenient location within your home where it can be easily seen and accessed. Ensure it is near a standard AC power outlet. The device does not require direct line-of-sight to the garage door opener but should be within a reasonable range for wireless communication.

2.3 Pairing with Your Garage Door Opener

The LiftMaster 829LM monitor must be paired with a MyQ-enabled garage door opener. Follow these steps to establish a connection:

1. Plug the power adapter into the monitor and then into a standard AC power outlet.
2. Locate the "Learn" button on the back of the 829LM monitor. Press and release this button. The monitor's indicator lights will begin to flash, indicating it is in pairing mode.
3. Within 60 seconds of pressing the monitor's "Learn" button, locate the "Learn" button on your MyQ-enabled garage door opener. Press and release this button.
4. The garage door opener will typically beep or flash its lights to confirm successful pairing. The monitor's indicator lights should also stop flashing and display the current status of the garage door (Green for closed, Red for open).
5. If pairing is unsuccessful, repeat the steps. If issues persist, refer to the Troubleshooting section.

Note: This monitor can be paired with up to four MyQ-enabled garage door openers. Repeat the pairing process for each additional opener.

3. Operation

3.1 Status Indicators

The monitor provides clear visual indicators for your garage door's status:

• Green LED: Indicates the garage door is fully closed.
• Red LED (flashing): Indicates the garage door is open.

3.2 Closing the Garage Door

To close an open garage door from the monitor:

1. Observe the Red LED indicating an open garage door.
2. Press the large "CLOSE DOOR" button on the monitor.
3. The garage door opener will emit a warning beep for several seconds before the door begins to close. This is a safety feature.
4. Once the door is fully closed, the Red LED will turn off, and the Green LED will illuminate.

Important: The monitor can only close the garage door; it cannot open it. If multiple doors are paired, pressing "CLOSE DOOR" will attempt to close all paired doors simultaneously.

3.3 Volume Control

The monitor features a volume control for the audible alert that sounds when the garage door is being opened. This alert can be adjusted or turned off:

• Locate the volume control button or switch on the monitor (often near the speaker icon).
• Adjust the volume to your preferred level or select the 'Off' position to disable the alert.

Note: The warning beep from the garage door opener itself (when closing remotely) is a mandatory safety feature and cannot be disabled via the monitor.

4. Maintenance

The LiftMaster 829LM Garage Door Monitor requires minimal maintenance.

• Cleaning: Wipe the device with a soft, dry cloth to remove dust. Do not use liquid cleaners or abrasive materials.
• Power: Ensure the power adapter is securely plugged into both the monitor and a functioning AC outlet.
• Batteries: This device does not use batteries. It is powered directly by the included AC adapter.
