3. Insert the CR2032 battery by placing it flat
against the prongs in the battery
compartment with the negative (

facing down. The battery should fit inside
the battery cradle.
4. Align the small tabs on the cover with the
slots in the track on the Sensor's body and
press the cover down onto the Sensor.
5. Use your thumb or finger to slide the cover
towards the other end of the Sensor until it
snaps into place.
6. When the battery is inserted correctly and
the cover is reattached, the red light on the
front of the Sensor will light up.
Confirm that the low battery alert has resolved and the equipment appears on your list of connected devices. You
should also ensure that sensor events such as door opening or motion registers as an activity on your system.
