- Normal Mode (Auto-Lock): By default, the door knob will automatically lock approximately 5 seconds after unlocking. This auto-lock duration can be adjusted via the TTLock app (5 seconds to 30 minutes).
- Passage Mode: In this mode, the door remains unlocked for continuous free entry and exit. This is useful for gatherings or when frequent access is needed. You can activate it via the app or by entering a specific code (e.g., 123) on the keypad after unlocking, followed by a prompt tone.
- Privacy Mode: This mode provides enhanced security by preventing external access. To activate, press and hold the button on the back of the interior handle for 1 second until you hear a prompt tone. This setting can also be managed through the app.
5.3 Silent Mode
You can activate silent mode via the TTLock app to disable sound prompts for undisturbed use, especially during quiet hours.
6. Maintenance
- Battery Replacement: When the low-battery alert sounds, replace all four AAA alkaline batteries promptly.
- Emergency Power: If batteries are completely depleted, connect a standard power bank to the Type-C emergency port on the exterior knob for temporary power to unlock the door. This port is for emergency power only and does not charge the internal batteries.
- Fingerprint Sensor Cleaning: Regularly wipe the fingerprint sensor with a soft, dry cloth to ensure optimal recognition performance.
- General Cleaning: Clean the door knob with a soft, damp cloth. Avoid abrasive cleaners or solvents.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Door knob does not power on. | Incorrect battery installation; loose connector wire. | Check battery polarity and ensure all 4 AAA batteries are correctly inserted. Verify the internal connector wire between the knobs is securely attached. |
| Fingerprint recognition fails frequently. | Finger is dirty, wet, or improperly placed; fingerprint not fully registered. | Ensure your finger is clean and dry. Place your finger firmly and completely on the sensor. Re-register your fingerprint from multiple angles for better accuracy. |
| Cannot connect to the app via Bluetooth. | Out of Bluetooth range; Bluetooth disabled on phone; lock not active. | Move closer to the door knob. Ensure Bluetooth is enabled on your smartphone. Touch the keypad on the door knob to wake it up before attempting to connect. |
| Door knob automatically locks when not desired (e.g., during a party). | Normal Mode is active. | Activate Passage Mode via the TTLock app or by entering the designated code (e.g., 123) on the keypad after unlocking. |
