4. Setup and Installation
Installation of the Protec Presence V2 Immobilizer should be performed by a qualified automotive technician. Incorrect installation can lead to vehicle damage or malfunction.
4.1. Wiring Diagram (Conceptual)
The main unit connects to your vehicle's electrical system to interrupt critical circuits (e.g., ignition, fuel pump) when the presence remote is not detected. Refer to the detailed wiring diagram provided in the physical manual for specific connections.
4.2. Remote Control Pairing
The remote controls are typically pre-paired with the main unit. If re-pairing is necessary, consult the specific instructions in the physical manual or contact technical support.
5. Operating Instructions
The Protec Presence V2 Immobilizer operates automatically based on the proximity of the remote control.
5.1. Arming the System
The system automatically arms when the vehicle's ignition is turned off and the presence remote control moves out of range (typically a few meters). A confirmation signal (e.g., LED indicator, subtle sound) may be emitted.

5.2. Disarming the System
The system automatically disarms when the presence remote control is detected within range of the main unit (e.g., when you approach the vehicle with the remote). The vehicle's ignition can then be started normally.
5.3. Anti-theft Activation
If the vehicle is started without the presence remote control, or if the remote moves out of range while the vehicle is running, the immobilizer will activate after a short delay. This will typically involve cutting off the engine or fuel supply, preventing the vehicle from being driven further.

6. Maintenance
The Protec Presence V2 Immobilizer requires minimal maintenance.
- Remote Control Battery: Replace the battery in the presence remote control when the indicator light dims or the range decreases. Refer to the physical manual for battery type and replacement instructions.
- Cleaning: Wipe the main unit and remote controls with a soft, dry cloth. Do not use harsh chemicals or abrasive cleaners.
- Regular Checks: Periodically test the system's arming and disarming functions to ensure proper operation.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| System does not arm. | Remote control still in range; faulty remote battery. | Ensure remote is out of range; replace remote battery. |
| Vehicle does not start (immobilized). | Remote control not detected; system armed. | Ensure remote is with you and within range; check remote battery. |
| Anti-theft activates unexpectedly. | Remote control moved out of range; signal interference. | Keep remote control with you at all times; avoid strong electromagnetic fields. |
If problems persist, contact Protec technical support.
