Checks and measures
Wipe the LCD carefully to
prevent scratching, using
tissue paper and an LCD
cleaner. To remove stub-
born dirt, use an LCD clean-
er, wiping slowly with tissue
paper so as to dissolve the
dirt. Change paper fre-
quently so the dirt will not
scratch the LCD.
Dust and dirt may be re-
moved with a soft cloth.
Check for corroded or loos-
ened nuts and bolts. If nec-
essary, clean and repaint
them thickly.
Replace them if heavily cor-
roded.
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 adhe-
sive as a temporary reme-
dy, then call for repair.
Open antenna cover to
check terminal strip and
plug connections inside.
Also check the rubber gas-
ket of antenna covers for

tions. Check contacts and
