8-4 Inspection and Cleaning
Clean and inspect the NT600S regularly to ensure that it is always used in its opti-
mum condition.
Cleaning Method If the display is dirty the screen is difficult to see. Clean the screen from time to time
as follows.
In daily cleaning, wipe the display with a soft dry cloth.
If the soiling cannot be removed witha dry cloth, wet the cloth with diluted neutral
detergent (2%), wring it out well and wipe the display with it.
If rubber or vinyl products, tape, etc. are left stuck to the display for long periods
they will cause staining. If such items are stuck to the display, remove them dur-
ing cleaning.
Never use volatile solvents such as benzene or thinners, or chemical dusters.
These could cause degeneration of the coatings of the NT600S display and body.
Inspection Method In normal environments, inspect the NT600S at intervals of between 6 months and
a year. In environments that are extremely hot and humid, or very dusty environ-
ments, shorten the inspection interval.
