- Remove Original Fuse: Carefully remove the fuel pump fuse from its slot. Store this original fuse in a safe place.
- Insert M506 Main Unit: Replace the removed fuse with the M506 main unit. The unit can be inserted in either direction (regardless of positive and negative directions). Ensure it is securely plugged into the fuse position.
- Secure the Device: Slightly bundle and secure the main unit and its wiring to prevent movement or interference.
- Close Hood: Close the vehicle's hood.
- Test Functionality: After installation, test the system's functionality in a safe environment before regular use.

6. Operating Modes
The M506 system offers two distinct operating modes:
6.1. Circuit Hidden Lock Mode (Default)
This is the factory default setting and is recommended for most users due to its stability.
- Activation: No short-circuit ring is inserted into the main unit.
- Operation: After ignition, the system requires a remote signal within 16 seconds to keep the engine running. If no signal is detected within this timeframe, the engine will shut off.
- Driving: Once the engine has started and received the initial signal, it will stay active even if the remote signal is lost during driving (e.g., remote is taken away, turned off, or out of battery). This prevents accidental engine cut-offs while the vehicle is in motion.

6.2. Anti-Robbery Mode (Advanced)
This mode offers enhanced security but should be used with caution, as it may not be suitable for all vehicles.
- Activation: Insert the provided short-circuit ring into the main unit. Refer to the image below for guidance.
- Operation: The engine requires continuous remote signal reception while driving. If the signal is lost for 30 seconds (e.g., remote is more than 10 meters away from the host), the engine will shut off.
- Caution: This mode may not be ideal for all vehicles, especially those with potential Bluetooth interference or signal instability. If you experience unintended engine shutdowns while driving, switch back to Hidden Lock Mode by removing the short-circuit ring.

7. Maintenance
7.1. Remote Control Battery Replacement
The remote controls are powered by Lithium Ion batteries. It is recommended to replace the battery if you observe any of the following:
- The remote control light dims or does not light up.
- The vehicle occasionally fails to start, indicating a weak signal from the remote.
The factory-installed battery is an industrial-grade, low-power battery. For optimal performance and reliability, it is highly recommended to replace it with a high-quality battery before initial use or when symptoms appear.

8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Engine does not start (within 16 seconds of ignition) | Remote control not detected or battery low. | Ensure remote is within range. Replace remote battery if dim or not lighting up. |
| Engine shuts off unexpectedly while driving (in Anti-Robbery Mode) | Remote signal lost due to distance, interference, or low battery. | Switch to Hidden Lock Mode by removing the short-circuit ring. Ensure remote battery is strong. Keep remote close to the vehicle. |
| Remote control light is dim or off | Remote control battery is low or depleted. | Replace the remote control battery with a new, high-quality Lithium Ion battery. |
| Difficulty installing the main unit | Incorrect fuse location or improper insertion. | Refer to your vehicle's manual for the correct fuel pump fuse location. Ensure the M506 unit is fully and securely inserted. If issues persist, consult a professional. |
