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.
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 household 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 solvents like
thinner, acetone or benzine for cleaning.
