When the battery low indicator lights up, or if the keypad becomes unresponsive, replace the batteries immediately. Always use 4 new AA batteries.
5.2 Cleaning
To clean the safe, use a soft, damp cloth. Avoid using abrasive cleaners or harsh chemicals, as these can damage the finish or electronic components.
6. Troubleshooting
- Safe does not open with digital code:
Ensure batteries are fresh and correctly installed. Verify that the correct code is being entered. If the code is forgotten, use the override key to open the safe and reset the code. - Keypad is unresponsive:
This usually indicates low or dead batteries. Replace all 4 AA batteries. - Override key does not work:
Ensure the key is fully inserted and turned correctly. Do not force the key. If the lock mechanism feels stiff, a small amount of graphite lubricant can be applied to the keyhole. - Safe door does not close properly:
Check for any obstructions around the door frame or locking bolts. Ensure the safe is on a level surface.
