2. CAUTIONS
Sensor Cannot Detect
When the sensor is frozen (operate normally when it's thawed)
When the sensor is covered with foreign materials such as snow or condensation
(if the foreign materials are removed, the sensor operates normally.) -
-
Not defective but improperly working
When the sensing portion is frozen (operates normally after thawed)
When reversing on rough roads, gravel roads, hills, or grass.
When receiving other ultrasonic signals (metal sounds or air braking noises from heavy
commercial vehicles).
When there is heavy rainfall or water drops.
When the sensor is covered with snow. -

-
-
-
Certain obstacles that sensors cannot detect
Thin and narrow objects, such as wires, ropes, or chains
Cotton, sponge, clothes, snow that absorb ultrasonic waves. -
-
Weak Sensing Scopes
When the ambient temperature is too high or too low.
