Circuit Hidden Lock Mode (Default – Recommended for Stability) Factory default setting (no short-circuit ring inserted). Engine stays active once started, even if the remote signal is lost during driving. How it works: After ignition, the system requires a remote signal within 16 seconds to keep the engine running. If no signal is detected, the engine shuts off only during startup—never while driving. Ideal for most vehicles to prevent accidental engine cutoffs caused by signal interruptions

Anti-Robbery Mode (Advanced – Use with Caution): Activated by inserting the short-circuit ring (included). Engine requires continuous remote signal reception while driving. If the signal is lost for 30 seconds, the engine shuts off. Important: This mode may not suit all vehicles (e.g., those with Bluetooth interference). If your car experiences unintended shutdowns while driving, switch back to Hidden Lock Mode (remove the short-circuit ring).

Effortless DIY Installation: Install in minutes! Simply: Locate your car’s fuel pump fuse (under the hood). Replace the fuse with the M506 main unit. Secure the device and close the hood. Pro Tip: Store the original fuse safely for future use

Safety Reminder:Test modes in a safe environment before regular use. Avoid Anti-Robbery Mode if your vehicle experiences signal instability. The default Hidden Lock Mode provides reliable theft prevention without driving risks
