sensor closer to the telephone base.
After testing the sensor signal strength, mark the mounting position on the garage door.
Then, remove the adhesive tape and proceed to the mounting process.

Test the sensor signal strength
• Use adhesive tape to hold the sensor temporarily in place.
• Mount the sensor to a higher position to avoid obstacles or blockages. Depending on
surroundings and obstructing factors, like walls or cabinets, the sensor may not transmit to the
telephone base properly.
Use your handset to enter the Sensor setup menu, and then select the Check signal menu.
Follow the steps to test the sensor's signal strength, and then exit the sensor setup mode. Make
sure you receive alerts when you open the door as usual.

• If No signal or Weak signal message is displayed in sensor setup mode, or if you do not receive an alert
when you open the door, move the telephone base closer to the mounting location or move the sensor
closer to the telephone base.
After testing the sensor signal strength, mark the mounting position on the door, window, or

4 Mount
We recommend you mount the magnet unit on a door, window, or medicine cabinet, and mount
the sensor unit on its respective frame.
You can use the spacers provided if there is a difference in level between the door and the
frame. The spacer will help to align your sensor to the correct height. You can also use a spacer
if the frame is too narrow or has some decorative molding.
NOTES
• You can mount the sensor unit with mounting tape first, and then use screws later if you decide to mount
it at that location for long term.
• Make sure the mounting surface is clean. A textured surface or any imperfections to a smooth surface can
keep the mounting tape from making a strong bond.
• Align the magnet unit with sensor unit when mounting.
• The distance between the sensor unit and magnet unit must be less than 1 cm (0.4 inch).
