Operating Instructions
This section outlines the basic functions of your Excalibur remote start and security system.
Remote Start
- Ensure the vehicle is in Park (automatic transmission) or neutral with parking brake engaged (manual transmission, if applicable).
- Press and hold the Start button on your 4-button remote for approximately 3 seconds.
- The vehicle's engine should start. The system will typically run the engine for a preset duration (e.g., 15 minutes) before shutting off.
- To turn off the engine remotely, press and hold the Start button again for 3 seconds.
Keyless Entry (Lock/Unlock)
- To Lock your vehicle's doors, press the Lock button on your remote once. The vehicle's lights may flash and/or horn may chirp to confirm.
- To Unlock your vehicle's doors, press the Unlock button on your remote once. The vehicle's lights may flash twice to confirm.
Security System Arming/Disarming
- The security system typically arms automatically when you lock the doors using the remote.
- To disarm the security system, unlock the doors using the remote.
- In case of an alarm trigger, the system will sound the siren and flash the lights. To silence the alarm, press any button on your remote.
Sidekick Remote
The Sidekick remote provides a compact alternative for basic lock, unlock, and remote start functions. Refer to its specific instructions for button assignments, which typically mirror the main remote's primary functions.
Maintenance
The Excalibur RS370 system is designed for minimal maintenance. However, consider the following:
- Remote Battery Replacement: If the remote's range decreases significantly or it stops responding, the battery may need replacement. Refer to the remote's casing for battery type (e.g., CR2032 coin cell) and replacement instructions.
- System Cleaning: Keep the main control module and remotes free from excessive dust and moisture. Wipe with a soft, dry cloth if necessary.
- Professional Check-ups: If you experience persistent issues, consult with your professional installer or an authorized service center.
Troubleshooting
If you encounter issues with your Excalibur system, try these common troubleshooting steps:
- Remote Not Responding: Check the remote battery. Ensure you are within the 1,500-foot operating range. Obstructions or strong radio interference can affect range.
- Remote Start Fails: Ensure the vehicle's doors are closed, hood is closed, and the parking brake is engaged. Check if the vehicle's battery is low. Some vehicles require specific conditions (e.g., gear in Park) for remote start to activate.
- Alarm Triggers Randomly: Check for loose wiring connections (professional inspection recommended). Ensure sensors are not overly sensitive (if adjustable).
- Vehicle Does Not Lock/Unlock: Verify the vehicle's central locking system is functioning correctly with the factory remote or manually. Check remote battery.
For persistent or complex issues, it is advisable to contact a professional installer or Excalibur customer support.
