1. After power on, the machine enters a self-check procedure

1. The white and red LEDs will remain on for 2 seconds before entering operation mode

2. Meanwhile, after the speaker remains sounding for 2 seconds, it enters operation mode.

2. Working Mode

1. The red LED indicator light flashes once every 2 seconds (3 Hz), then enters an intermittent state after 10 seconds, lasting for 100 seconds, and repeats thereafter.

2. White LED flashes for 2 seconds (6 Hz) – pauses for 2 seconds – flashes for 2 seconds (2 Hz) – pauses for 2 seconds – flashes for 2 seconds (4 Hz), followed by an intermittent state, lasting 100 seconds, and then repeated.

3. The ultrasonic speaker operates in a sweep mode at 18 kHz–36 kHz for 4 seconds—then pauses for 3 seconds—followed by 18 kHz.

After 3,600 Hz scanning, it enters an intermittent state after 3 seconds, lasting for 100 seconds, and then repeats.

The above three items operate simultaneously

4. During the intermittent state, the green indicator light flashes once every 5 seconds

3. When the vehicle starts, the vibration sensor activates, and the above operating mode is stopped. After the last vibration, the machine re-enters the operating mode 120 seconds later. During this period, the red indicator light flashes once every 5 seconds.

Ultrasonic output decibels: 100-110 DB.

Test precautions:

1. Is the battery spring installed in the wrong position?

2. The battery must be tested in practice.

3. Does the external power supply test light illuminate?
