5-2 Cleaning and Inspecting
Clean and inspect the NSA-series Industrial PC regularly to ensure optimal
performance.
5-2-1 Cleaning
The display becomes difficult to read when it gets dirty. Be sure to clean it
regularly as described below.
Use a soft, dry cloth to wipe off the display every day. Do not use excessive force
to clean a display that is very dirty because you may damage the front panel.
Instead, moisten the cloth first to remove the dirt.
•
If wiping the display with a dry cloth fails to remove the dirt, moisten the cloth
with a highly diluted solution of mild detergent (2%) and then wring the cloth
well before using it to wipe off the display.
•
Adhering rubber, vinyl, or tape to the Unit for extended periods of time will
stain the NSA-series Industrial PC. Remove these items from the Unit each
time you clean it.
Note
Never use chemically treated cloth or volatile solvents, such as benzene or thinner, to
clean the product.
5-2-2 Inspecting
Inspect the NSA-series Industrial PC once or twice a year. Shorten the interval
between inspections if the operating environment is extremely warm, moist, or
dusty.
Inspection Items
Inspect the following items to make sure they are within acceptable levels
according to the judgment criteria. If the inspection results fall outside these levels,
improve the operating environment and re-tighten screws or take other measures
to bring the results back within the acceptable range.
