General Care

Your ultrasonic sensor is very low maintenance and will need little care as long as it was installed 

correctly. However, in general, you should periodically inspect your DST sensor to ensure the 

sensor face is free of any buildup that might impede the function of the sensor. If sediment or other 

foreign matter becomes trapped on the sensor face, detection errors can occur.

If you need to remove the sensor, be sure to store it in a dry place at a temperature between -40° 

and 180° F. 

If your 

DST ultrasonic sensor 

needs repair, contact us via email, phone, or online chat on our 

website. We will issue you an RMA number with instructions.
