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.
-
When a 1 m or less long small object with a diagmeter of 100 mm or less is detected.
