Setup
Battery Installation
The disc lock comes with pre-installed batteries and an additional set. If the alarm does not activate or sounds weak, you may need to replace the batteries. Refer to the 'Battery Replacement' section under Maintenance for detailed instructions.
Initial Check
Before first use, ensure the disc lock functions correctly:
- Insert a key and turn it to ensure the locking pin retracts smoothly.
- Press the locking pin down without a key to test the keyless locking mechanism.
- Gently shake the locked device to confirm the alarm activates.
Operating Instructions
Locking the Device and Activating the Alarm
- Position the disc lock on your vehicle's disc brake, ensuring the locking pin passes through one of the holes in the disc.
- Press the lock cylinder down firmly until you hear a single 'beep'. This indicates the lock is engaged and the alarm system is armed.
- After the 'beep', the alarm will be active. Any significant vibration or movement will trigger a warning (3 beeps), followed by a full 110 dB alarm (10 beeps) if the disturbance continues.
