To change the batteries on your Recessed Door Sensor:
- Remove the cover by inserting a small object into the latch and popping it off.
- Slide the circuit board out of the casing the replace the CR2 battery from its compartment. The positive end should be facing towards the circuit board.
- Once complete, place the circuit board inside the casing and put the cap back on the outside of the sensor.
