8. Maintenance
- Battery Replacement: When the alarm sound becomes weak or the remote control range decreases, it's time to replace the AAA batteries in the alarm unit. Replace all three batteries simultaneously for optimal performance.
- Cleaning: Wipe the alarm unit with a soft, dry cloth. Do not use harsh chemicals or abrasive cleaners.
- Water Exposure: While the alarm is IP55 waterproof, meaning it is protected against low-pressure water jets from any direction, avoid submerging it in water or exposing it to high-pressure water streams. Ensure the battery compartment is securely closed.
- Storage: If storing the alarm for an extended period, remove the batteries to prevent leakage and damage to the unit.
