5.2 Scanner Unit
When performing maintenance or inspection of the scanner unit, be sure to shut off
the main power source.
If the scanner suddenly rotates and it hits the human body violently, there is a risk
of dying or getting a serious injury of any person.
Be sure to shut off the main power source when approaching the scanner unit for
the purposes of maintenance or inspection.
If exposured to electric waves at proximate distances, there is a risk of dying or
getting a serious injury of any person.
(1) Radiation unit
If the front of the radiation unit is soiled with soot, salt, paint specks, bird excrement or other
alien matter, electric waves may become attenuated and reflection may occur thus causing
degradation in the performance of the radar.
The radiation unit should be inspected and always kept clean by wiping with cloth soaked in
alcohol or water in the event of soiling.
Solvents such as gasoline, benzene, trichlene or ketone should never be used for this purpose.
(2) Pedestal
The pedestal and attachment bolts of the scanner unit should be inspected periodically for
erosion and maintained to ensure safety. Painting is the best measure for preventing
erosion and it is recommended that this be undertaken once in half a year.
5.3 Display Unit
Cleaning the LCD
When dust adheres to the LCD, transparency degrades and the images become dark.
Cleaning is performed using cloth soaked in water (flannel or cotton). Wiping vigorously
with dry cloth or the use of gasoline or thinner should be avoided.
Caution

Vigorous wiping with dry cloth or the use of gasoline or thinner should be
avoided in cleaning the LCD.
Such action may cause scratches and deterioration.
