Alarm Range
Upon detecting an object at each range out of 3 ranges as stated below within the operation range, it will generate alarm.
First alarm: Object comes near to the sensor located at the rear of vehicle, within 81-120 cm ± 15 cm
Second alarm: Object comes near to the sensor located at the rear of vehicle, within 41-80 cm ± 10 cm
Third alarm: Object comes near to the sensor located at the rear of vehicle, within 40 cm ± 10 cm
NOTE:
- Time tolerance of the above waveform: Time ± 10%
- At nearer distance than 40 cm, detection may not occur.
- Alarm will be generated with vehicle reversing speed 10 km/h or less.
For moving target, maximum operation speed shall be target approach speed of 10 km/h.
- When the vehicle or the target is moving, sequential alarm generation or effective alarm may be failed.
- False alarm, or failure of the alarm to trigger 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 to the sensor.
- Dirt on the sensor.
- Sequential alarm may not occur due to the reversing speed or the target shape.
