This chapter tells you how to keep your
radar in good working order. Before
reviewing this chapter please read the
safety information which follows.

                Only qualified personnel should 
                work inside the equipment.

                  The radar antenna emits high 

                  frequency radio radiation which 

can be harmful, particularly to your eyes. 

Never look directly into the antenna from a 

distance of less than 1 m when the radar is 

in operation as you could injure the cornea 

of your eyes. Always make sure the radar is 

set to stand-by or is turned off before 

starting work on the antenna unit.

Regular maintenance is important for good
performance. Always keep the equipment
as free as possible from dirt, dust, and
water splashes. Make sure all screws
securing the components are properly
tightened.

A maintenance program should be
established and should at least include the
items listed in Table 4-1.

Check for corrorded or loosened nuts 
and bolts. If necessary, clean and 
repaint them thickly. Replace them if 
heavily corroded.

Check for dirt and cracks on radiator 
surface. thick dirt should be wiped off 
with soft cloth dampened with fresh 
water. If a crack is found, apply a slight 
amount of sealing compound or 
adhesive as a temporary remedy, then 
call for repair.

Open antenna cover to check terminal 
strip and plug connections inside. Also 
check the rubber gasket of antenna 
covers for deterioration.

The LCD will, in time, accumulate a 
coating of dust which tends to dim the 
picture. Wipe LCD lightly with a soft 
cloth.

Check for tight connection and 
corrosion.

Sealing compound may be used 
instead of paint. Apply a small 
amount of grease between nuts 
and bolts for easy removal in future.

Do not use plastic solvent (acetone) 
for cleaning. If you need to remove 
ice from antenna unit, use a 
wooden hammer or plastic head 
hammer. Crack on the unit may 
cause water ingress, causing 
serious damages to internal circuits.

When closing antenna covers in 
position, be careful not to catch 
loose wires between covers and 
unit.

Do not use chemical cleaners to 
clean any part of the display unit; 
they can remove paint and 
markings.

If corroded, contact your dealer
for replacement.
