8. Maintenance
8.1. Battery Replacement
Alarm Unit Batteries: The alarm unit uses 3 AAA batteries. When the alarm sound becomes weak or the unit fails to respond, it's time to replace the batteries. Use a small screwdriver to open the battery compartment, replace the old batteries with new ones, ensuring correct polarity, and securely close the compartment.
Remote Control Battery: The remote control uses one 12V/27A alkaline battery. If the remote's range decreases significantly or it stops functioning, replace its battery. Use a small screwdriver to open the remote's casing, replace the battery, and reassemble.
8.2. Cleaning
Wipe the alarm unit and remote control with a soft, dry cloth. Avoid using harsh chemicals or abrasive cleaners, as these can damage the device's finish or internal components. The IP55 rating protects against water splashes and dust, but avoid submerging the unit in water.
