LCD monitor and
processor unit
3 to 6 months Cabling
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.
Check and measures
Dust or dirt may be removed from the cabinet
with a soft cloth. Water-diluted mild detergent
may be used if desired. DO NOT use chemical
cleaners to clean the display unit; they may
remove paint and markings. To clean the LCD,
wipe the LCD carefully to prevent scratching,
using tissue paper and an LCD cleaner. 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 frequently so the
salt or dirt will not scratch the LCD. Do not use
solvents such as thinner, acetone or benzene for
cleaning. Also, do not use a degreaser or an
antifog solution, as they can strip the coating
from the LCD.
Check that all cabling is firmly connected and is
not damaged.
NOTICE
Do not use chemical-
based cleaners to clean
either unit. They can
remove paint and
markings.
