- Battery Replacement: Replace batteries promptly when the low battery reminder activates. Always use LR3/LR03 alkaline dry batteries.
- Cleaning: Wipe the lock surface with a soft, dry cloth. Avoid using abrasive cleaners or solvents that could damage the finish or electronic components.
- Environmental Conditions: Avoid installing the lock in locations exposed to prolonged direct sunlight or excessive moisture, as high temperatures or water exposure can damage internal components.
9. Troubleshooting
If you encounter issues with your GEKRONE Smart Lever Lock, consider the following common solutions:
- Lock Not Responding: Check battery levels. If low, replace with new alkaline batteries or use the emergency USB power.
- Fingerprint Recognition Issues: Ensure your finger is clean and dry. Try re-registering your fingerprint if issues persist. Ensure proper placement on the sensor.
- Digital Password Not Working: Verify the correct password sequence. Remember the anti-peeping function allows extra digits before and after the actual code.
