- Close the battery compartment cover.
2. Cleaning
To maintain the appearance and functionality of your safe:
- Clean the safe's exterior with a soft, slightly damp cloth.

- Keep the fingerprint scanner clean and free of dust, dirt, or moisture to ensure optimal performance.
Troubleshooting
- Safe does not open with fingerprint:
Ensure your finger is clean and dry. Try placing your finger firmly and flatly on the scanner. Re-register your fingerprint if issues persist. Check if the batteries are low and replace them if necessary. - No power or display:
Check that the batteries are inserted with correct polarity. Replace all batteries with new AA alkaline batteries. - Emergency key does not work:
Ensure the key is fully inserted into the keyhole and turned completely. Do not force the key. If the key is bent or damaged, contact customer support. - Safe beeps continuously:
This may indicate a low battery warning or an error. Check the display for specific error codes or messages. Replace batteries if indicated.
