6.2.12.2 Installing the Battery
When the system indicates the sensor battery is low, replace it immediately. Use the
recommended replacement batteries.
To replace the battery, do the following:
1. To remove the sensor cover from the base, press a flathead screwdriver into the
slot on the bottom of the sensor, (see Figure 77), and turn the screwdriver 90
degrees.
2. Place a small flathead screwdriver in the slot between the metal clip and the
battery, then twist the screwdriver slightly while holding back one of the black
plastic edges holding the battery. Dispose of the battery as required by local
laws.
3. Insert the replacement battery with the + sign facing up.
4. Verify programming and RF communication with the Digital Life Controller.
5. Replace the sensor cover on the base. Align the tamper switch with the plastic
tamper tap (See Figure 77.) and snap the cover down on the base.
