Check
Check for looseness and rust.
Check the ground terminal is not
loosened or rusty and that the
ground wire is properly grounded.
Check antenna for damage.
Check the LCD surface for dust and
dirt. The LCD will, in time, accumu-
late a coating of dust which tends to
dim the picture.
Note: The life of the LCD is approx.
100,000 hour. When the LCD has
expired, the brilliance cannot be
raised.
NOTICE
Do not apply paint, anti-corrosive
sealant or contact spray to coating or
plastic parts of the equipment.
Those items contain organic solvents that
can damage coating and plastic parts,
especially plastic connectors.
• Refasten if necessary.
• Remove rust if necessary.
Replace the antenna if damaged.
Wipe the LCD carefully to prevent
scratching, using the cleaning cloth
provided and an LCD cleaner.
To remove dirt or salt deposits, use
an LCD cleaner, wiping slowly with
cleaning cloth so as to dissolve the
dirt or salt. Do not use solvents such
as thinner, acetone or benzene for
cleaning. Also, do not use degreaser
or antifog solution on the LCD, as
they can strip the coating on the
LCD.
