3. It should work properly, if a person is at a distance
of 1 m away from the front of the sensors.
a. When testing sensors, if buzzer gives continuous
sound, check whether some parts of the car or
some unwanted objects fall into the detecting
range, or the hole is too small thus the sensor is
fitted over tightly in it , or the sensors are near
to some strong interference sources (such as
exhaust pipe, other wires).
b. If the buzzer sounds but there is nothing in front
of the sensor, maybe the sensor is detecting the
ground, check the position and direction of the
sensor. The sensors should be slightly raised in
horizontal. The sensors may detect protruding
objects in the back, such as the license plate, the
spare tyre and the bumper. In this case, slightly
adjust the sensors' position.
c. If the problems could not be solved, the sensors
can be deemed as defective or the sensors
do not match with the control box. The whole
system should be replaced.
Note:
• The sensors & the control box, the sensors & the
jacks are matched on a one-to-one basis.
• For safety reasons, buzzer will sense 0.0 instead
of 0.3 to 0.1 when detect something in the
distance of 0.0 to 0.4m. In this situation, the
driver should park the car immediately. When the
distance is within 0.5m, the alarm sound will keep
1 second longer. Please pay attention to this while
making adjustments.
