Check point(s)
Check that all cabling is secure-
ly fastened and free of all types
of corrosion.
Dust/grime on case.

buildup.
NOTICE
Do not apply paint, anti-corrosive
sealant or contact spray to coating

Those items contain organic solvents
that can damage coating and plastic
parts, especially plastic connectors.
Remedy
Reconnect if necessary.
Replace if necessary.
Remove dust with a soft, lint free cloth.
Where the dust is especially difficult to
remove, use a mild strength house-
hold detergent to dampen the cloth.
After cleaning, use a dry, soft lint free
cloth of wipe the unit dry.
Do not use acetone, thinners or other
chemicals as they may damage the
unit or remove markings.
Clean the LCD carefully to prevent
damage, with tissue paper and an
LCD cleaner. To remove dirt or salt
deposits, use an LCD cleaner and
wipe slowly with lens paper so as to
dissolve the dirt or salt. Change the
paper frequently so the salt or dirt will
not damage the LCD. Do not use sol-
vents like thinner, acetone or benzine
for cleaning.
