Safety Information
- Always disconnect the vehicle's battery before performing any electrical installation to prevent short circuits or electrical shock.
- Ensure all wiring connections are secure and properly insulated to prevent corrosion and electrical hazards.
- Mount the alarm in a location where it is protected from direct impact and excessive heat.
- Verify that the alarm's sound is not obstructed and can be clearly heard by individuals around the vehicle.
- This device is an aid for safety; always exercise caution and check surroundings visually when reversing.
Installation
- Choose Mounting Location: Select a suitable location at the rear of the vehicle, ensuring the alarm is securely mounted and its sound is not muffled. The location should also protect the alarm from physical damage.
- Connect Positive Wire: Connect the positive screw terminal of the alarm to the vehicle's reversing light power cord or to the reversing switch on the dashboard. This connection should only receive power when the vehicle is in reverse gear.
- Connect Negative Wire (Ground): Connect the other wire from the alarm to a reliable ground point on the vehicle chassis (negative terminal).
- Test Functionality: After installation, re-connect the vehicle's battery. Engage reverse gear (with the engine running or ignition on, as appropriate for your vehicle) to verify that the alarm sounds correctly.

Maintenance
- Regular Inspection: Periodically check the alarm for any visible damage, loose connections, or corrosion.
- Cleaning: Keep the alarm's speaker grille free from dirt, mud, and debris to ensure optimal sound output. Use a soft, damp cloth for cleaning. Do not use harsh chemicals or abrasive cleaners.
- Wiring Integrity: Ensure that the wiring remains intact and securely connected. Repair or replace any frayed or damaged wires immediately.
- Environmental Protection: While the alarm is weather-resistant, prolonged exposure to extreme conditions may affect its lifespan.
Troubleshooting
- Alarm Does Not Sound:
- Check all wiring connections for looseness or corrosion.
- Verify that the vehicle's reverse lights are functioning, indicating power to the circuit.
- Ensure the vehicle's battery is adequately charged.
- Inspect the alarm unit for any physical damage.
- Alarm Sounds Weakly or Intermittently:
- Check for debris or obstructions in the speaker grille.
- Inspect wiring for partial breaks or poor connections.
- Ensure the alarm is receiving the correct voltage (12V-80V DC).
- Alarm Sounds Continuously (Not only in Reverse):
- This indicates incorrect wiring. Re-check the positive connection to ensure it is only receiving power when the vehicle is in reverse. It may be connected to a constant power source.
