cabinet that opens or closes.
1. Take the sensor unit and magnet unit to the desired mounting
location, and hold them at the object and the frame respectively.

Sensor setup menu. Follow the steps to test the sensor's signal
strength, and then exit the sensor setup mode.
3. Open the door, window, or medicine cabinet again to make sure
you receive alerts.

If No signal or Weak signal message is displayed in sensor setup mode,
•
or if there is no alert announcement when you open the door, move the
base closer to the mounting location or move the sensor closer to the
base.
• Use adhesive tape to hold the sensor temporarily in place.
• Depending on surroundings and obstructing factors, like walls or
cabinets, the sensor may not transmit to the base properly.
