Check and measures
To clean the LCD, wipe the LCD
carefully to prevent scratching, us-
ing tissue paper and an LCD clean-
er. To remove dirt or salt deposits,
use an LCD cleaner, wiping slowly
with tissue paper so as to dissolve
the dirt or salt. Change paper fre-
quently so the salt or dirt will not
scratch the LCD. Do not use sol-
vents such as thinner, acetone or
benzene for cleaning. Also, do not
use a degreaser or an antifog solu-
tion, as they can strip the coating
from the LCD.
Check that all cabling is firmly con-
nected and is not damaged.
NOTICE
Do not apply paint, anti-corrosive sealant
or contact spray to coating or plastic parts.
Those items contain organic solvents that can
damage coating and plastic parts, especially
plastic connectors.
Remarks
Do not use chemical-
based cleaners for

ings.
