5. Installation
The MIRKOO Backup Alarm is designed for easy installation. Follow these steps:
- Choose a Mounting Location: Select a secure location on the vehicle, typically near the rear, where the sound can be clearly heard and the alarm is protected from direct impact. Ensure the mounting surface is flat and stable.
- Secure the Alarm: Use appropriate fasteners (not included) to securely mount the alarm to the chosen location.
- Wire the Positive Connection: Splice a wire from the positive screw terminal of the alarm to the power wires of the vehicle's reverse light. Alternatively, connect it to a reverse switch installed on the dashboard. This connection should only receive power when the vehicle is in reverse.
- Wire the Negative Connection: Splice a wire from the negative screw terminal of the alarm to a reliable ground point on the vehicle chassis (negative wire).
- Test the Installation: Once wired, carefully test the alarm by engaging reverse gear (with the engine running and foot on the brake, or in a safe, open area). The alarm should emit a clear, loud beeping sound.

6. Operation
The MIRKOO Backup Alarm operates automatically. Once correctly installed and wired to the reverse light circuit, it will activate and emit a continuous 110dB beeping sound whenever the vehicle is shifted into reverse gear. This provides an audible warning to individuals and objects behind the vehicle, significantly reducing the risk of accidents.
