8. Troubleshooting

If you encounter issues with your CHADWICK CW-8101 car alarm system, please refer to the following common troubleshooting tips:

• False Alarms: If the alarm triggers frequently without apparent cause, the sensitivity setting might be too high. Try reducing the sensitivity level (refer to Section 6.2). Environmental factors like strong winds, heavy rain, or passing large vehicles can sometimes trigger highly sensitive alarms.
• Alarm Not Triggering: Ensure the system is armed correctly (siren sounds once after pressing the lock button). If the alarm is not triggering even with significant impact, the sensitivity might be too low. Try increasing the sensitivity level (refer to Section 6.1).
• Remote Control Not Working: Check the batteries in the remote control. Replace them if necessary (CR2016*2). Ensure you are within the effective range of the alarm system.
• No Power to Unit: Verify that the red and black wires are securely connected to the correct terminals of the 12V car battery. Check for any loose connections or blown fuses in the wiring.
