REVERSE RADAR SYSTEM

PRECAUTION

1 . Check causes for the abnormal test functions of the reverse radar system:
(a) The probe of reverse radar is covered by mud or snow and other impurities (the test
functions will recover after cleaning the sensor).
04
(b) The reverse radar sensor is freezed (the test functions will return to normal after the
temperature of the sensor rises).
(c) The reverse radar probe is covered.

2 . The test scope is affected by the following conditions:
(a) The reverse radar probe is covered by the mud or snow and other impurities.
(b) The vehicle is located at the extremely hot or cold areas.
3 . The reverse radar probe may encounter test errors, for example:
(a) The vehicle will travel on rugged roads, unpaved roads or in the tall glasses.
(b) The horn sound, engine sound of motorcycle, the sound of air brake of large vehicles
or the ultrasonic wave of the sonar of another vehicle transmitted from nearby.
(c) In case of heavy rain, or the reverse radar probe exposed to water.
(d) The vehicle slants substantially.
(e) The vehicle is equipped with additional purchased protection rod or wireless core
antenna.
(f) The reverse radar probe is covered by the mud or snow and other impurities.
(g) The vehicle is moving toward the edge of the object.
4 . The reverse radar probe can not test some objects:
(a) Such as line, rope and other thin objects.
(b) Such as cotton, snow and other material that can absorb ultrasonic
(c) Objects whose edges are sharp
(d) Short and small objects
5 . Other precautions:
(a) The reverse radar probe cannot check the objects directly under the beam.
(b) The reverse radar probe cannot check obstacles too close to it.
(c) The reverse radar probe cannot check the obstacles if it drops or is fiercely shocked.
