(We recommend using two pieces of cloth. One for wet wipes and another for dry wipes)

2. Daily maintenance
Before beginning daily operation of the sensor, use the compressed air duster to remove
the dust and dirt from the shaded area.
3. Routine maintenance
1) Dampen the wet wiping cloth with water and squeeze hard to get excess water out until no
water droplets drip. If only one piece of cloth is used, leave another corner dry for dry wipes.
Use neutral detergent diluted with water for stubborn dirt and oil stain.
2) Use the compressed air duster to remove overall dust as described in the daily
maintenance. The lens may be scratched if it is wiped with abrasive particles or dust on the
surface.
