5.2 Regular service and cleaning up

Periodic inspection and cleaning is essential to keep the radar system in the good working order for the

life of the radar.

5.2.1 Monthly inspection

(1) Check whether there is any dirt or soot on the radiating part of the Antenna unit. If any, wipe it with

soft cloth soaked in water or soap detergent. Also make sure no cracks or coating material is on the

front radiation part of Antenna unit.

Never turn on the power of radar system under inspection.

To prevent electric shock, be sure to turn off the radar system power before

opening the cover of the antenna unit.
