4. Mode d'emploi

The CHADWICK 501A system offers both automatic and manual operating modes.

4.1 Automatic Mode (Proximity Sensing)

In automatic mode, the system detects the presence of the remote control. The engine's oil circuit will be enabled or disabled based on your proximity to the vehicle.

  • Approaching the Vehicle: When the owner, carrying the remote control, approaches the vehicle (sensing distance approximately 15 meters), the system automatically disarms, opening the engine oil circuit. This allows the vehicle to start normally.
  • Leaving the Vehicle: When the owner, carrying the remote control, leaves the vehicle, the system automatically arms, disconnecting the engine oil circuit. This prevents the engine from starting.

In manual mode, the system requires interaction with the remote control to enable the engine. If the remote control button is not pressed after starting the engine, the engine will stop after approximately 25 seconds. To start the car normally, ensure the remote control button is pressed.

Télécommande 4.3

The system includes two remote controls. These remotes use a CR2032 battery and do not require charging. They are used for sensing signals and switching between operating modes.
