7.1 Battery Replacement (Call Button)
Each call button is powered by a CR2032 Lithium Ion battery, which typically lasts for approximately 6 months. When the battery is low, the button's indicator light may not illuminate or the signal range may decrease. To replace the battery:
- Carefully open the back cover of the call button.
- Remove the old CR2032 battery.
- Insert a new CR2032 battery, ensuring correct polarity (+/-).
- Close the back cover securely.

7.2 Cleaning
Wipe the devices with a soft, dry cloth. Do not use abrasive cleaners or solvents.
8. Troubleshooting
- Alarm not activating: Ensure the call button battery is not depleted. Re-pair the call button with the strobe siren if necessary (refer to Section 5.3). Check if the strobe siren is powered on.
- Weak signal or limited range: Replace the call button battery. Ensure there are no significant obstructions (thick walls, metal objects) between the call button and the strobe siren. The maximum range is approximately 262 feet in open areas.
- No sound from siren: Check the volume setting on the strobe siren (refer to Section 6.3). Ensure the siren is not in mute mode.
