3. Maintenance
3.1 Battery Replacement
The safe will provide an 'Under Voltage Warning' when the battery level is low (below 4.8V). This is indicated by a prompt sound. Replace the 4 AA batteries promptly to ensure continuous operation of the electronic lock system. The fingerprint memory function ensures your code will not be lost during battery replacement.
3.2 Cleaning
Clean the exterior of the safe with a soft, damp cloth. Avoid using abrasive cleaners or solvents that could damage the finish. For the interior, a soft brush or vacuum can be used to remove dust and debris.
3.3 Lock Mechanism Care
Periodically check the lock mechanism and bolts for any obstructions. Keep the keypad and fingerprint scanner clean and dry for optimal performance.
4. Troubleshooting
4.1 Dual Alarm System
The safe is equipped with a dual alarm system:
- Incorrect Code/Fingerprint Alarm: If 3 consecutive incorrect codes are entered or 5 consecutive incorrect fingerprints are scanned, the alarm system will activate for 30 seconds.
- Vibration Alarm: If the gun cabinet is moved violently or shaken, the vibration alarm will be triggered immediately. To activate the vibration alarm mode, press the '*' button.
The alarm sound can reach up to 70 decibels.
4.2 Door Not Locking Properly
If the door does not lock when turning the knob, ensure the door is perfectly aligned with the safe frame. Misalignment can prevent the security bolts from engaging correctly.
4.3 Keypad Unresponsive
If the keypad is unresponsive, check the battery level. If the batteries are low or dead, use the external Type-C power cable to temporarily power the unit or replace the batteries.
