Alarm Range
First alarm: Object comes near to the sensor located at the rear of vehicle, within 81-120cm +/- 15cm
Second alarm: Object comes near to the sensor located at the rear of vehicle, within 41-80cm +/- 10cm
Third alarm: Object comes near to the sensor located at the rear of vehicle, within 40cm +/- 10cm
NOTE:
- Time tolerance of the above waveform: Time +/- 10%
- At nearer distance than 40cm, detection may not occur.
- Alarm will be generated with vehicle reversing speed 10km/h or less.
For moving target, maximum operation speed shall be target approach speed of 10km/h.
- When the vehicle or the target is moving, sequential alarm generation or effective alarm may be fail.
- False alarm may occur in the following conditions.
- Irregular road surface, gravel road, reversing toward grass.
- Horn, motor cycle engine noise, large vehicle air brake, or other object generating ultrasonic wave is near.
- When a wireless transmitter is used near the sensor.
- Dirt on the sensor.
- Sequential alarm may not occur due to the reversing speed or the target shape.
