Maintenance
To operate the radar equipment in a good condition for a long period of time, perform the inspection and
cleaning periodically.
4.1.1 Monthly Inspection
Caution:
Do not turn on the power of the radar during
inspection.
(1) To protect the LCD and enhance the visibility, the acrylic filter is installed on the surface. If the
acrylic filter is dirty, an image cannot be clearly seen. If dirty, dip a soft cloth into a neutral
detergent, wring it lightly and wipe the filter surface lightly with the cloth. Do not use a dry cloth. If
done so, due to static electricity, the acrylic filter will attract dust.
Caution Never use a thinner solvent. The filter surface will be
chemically decomposed, resulting in the loss of the
transparency.

(2) Check that the radiation surface of the antenna is not dirtied by soot. Dip a soft cloth into water or
soap water, wring lightly and wipe the antenna with the cloth. Check for damage and paint
sticking.
Note: Before performing the maintenance and inspection of the antenna, thread a string
through the hole of radome (upper) as illustrated below and hang it up.
