Battery Replacement Instructions
Recessed Door Transmitter
Ademco 5818

1. Remove the transmitter’s end cap by inserting the flat blade of a small screwdriver in the cap’s slot and turning slightly counterclockwise.

2. Slide the transmitter PC board assembly out of its case, taking care not to bend the antenna during this step or later.

3. Remove the old battery, if replacing it.

4. Observe correct polarity and insert the fresh battery into the battery holder (+ and – polarity indications are inside). See diagram.

5. Slide the PC board assembly back into its case, battery end first (the reed switch end must be toward the cap).

6. Replace the end cap. Line up the projections on the cap with the openings at the edge of the case. Press the cap gently against the PC board and turn the cap (via its slot) slightly clockwise, thereby locking it in place.

Battery Caution
Risk of fire, explosion, and burns. Do not recharge, disassemble, heat above 100°C, or incinerate. Dispose of used batteries promptly. Keep away from children
