6. Operating Instructions
6.1 Unlocking the Door
- Using Touch Screen Keypad: Enter your registered password on the touch screen. The lock will disengage. The spy-proof random code system prevents fingerprint traces from revealing your password.
- Using RFID Card: Place a registered RFID card over the card reader area on the exterior unit. The lock will disengage.
- From Inside: Press the 'OPEN' button on the interior unit to unlock the door.
6.2 Locking the Door
- Automatic Locking: The SHS-1321 features an automatic locking mechanism. After the door closes, the deadbolt will automatically extend and lock after a few seconds.
- Manual Locking: If desired, you can manually engage the lock from the interior using the manual knob.
- Double Lock (Privacy Mode): From the interior, press the 'DOUBLE LOCK' button to activate privacy mode. This prevents unlocking from the exterior using passwords or RFID cards.
6.3 Volume Adjustment
The lock's sound volume can be adjusted according to your preference. Refer to the detailed installation manual for specific steps on how to modify the volume settings.
7. Maintenance
- Cleaning: Wipe the exterior and interior units with a soft, dry cloth. Do not use abrasive cleaners or solvents, as they may damage the finish or electronic components.
- Battery Replacement: Replace all 4 AA batteries when the low battery indicator is active. Always use new, high-quality alkaline batteries.
- Door Alignment: Periodically check that your door is properly aligned and that the deadbolt extends and retracts smoothly without obstruction.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Lock does not respond to keypad or RFID card. | Dead batteries; incorrect password/card; lock is in privacy mode. | Replace batteries; re-enter correct password/use registered card; deactivate privacy mode from inside. |
| Automatic locking fails. | Door misalignment; obstruction in deadbolt path. | Check door alignment and clear any obstructions. |
| Lock automatically engages for several minutes after multiple incorrect attempts. | Security feature activated due to unauthorized access attempts. | Wait for the lock to reset (typically a few minutes) before attempting to unlock again. |
| Difficulty registering multiple RFID cards. | Incorrect procedure for continuous card registration. | After pressing the registration button, continuously scan all cards one after another without pressing the registration button again until all cards are scanned. Then finalize the registration. |
