Removal
1. Power off the sensor by pressing the power button for approximately three seconds until the button LED flashes red.
2. Remove the sensor top by unscrewing the four top screws (#2 Phillips), then lift the lid up and off the enclosure base.
3. The battery is shrink-wrapped and wired with a pin connector; grab the wire pair from the battery near the base of the connector and pull straight up and out firmly while pushing down on the foam inside the sensor enclosure.
Installation
1. The battery connector is keyed, so it can only be installed in one direction.
2. Align the key tabs and push the connector into the slot firmly.
3. Lay the battery across the foam inside the enclosure as indicated, ensuring the battery and battery wires are away from the sealing edge of the enclosure wall.
4. Place the lid back on the enclosure.
5. Use a torque wrench or screwdriver with the following specifications for securing the screws to the top of the housing. Tighten screws using a Phillips head bit set to 0.9 Nm / 7.9 in-lbs.
6. Tighten the screws in a star pattern to not put undue pressure on one side of the seal, or pop the seal out one side.
