Inspection And Cleaning - Omron NS7 Series Setup Manual

7-2 Inspection and Cleaning

Clean and inspect the PT periodically to maintain it in optimum condition for use.
@ Cleaning Methods
The screen visibility will be impaired if the display becomes dirty. Clean the display periodi-
cally using the following methods:
• For daily cleaning, wipe with a soft, dry cloth. Attempting to remove heavy dirt with the
cloth may scratch the front panel sheet. Use a damp cloth and wipe the surface again to
remove dirt.
• If dirt cannot be removed using a dry cloth, dampen the cloth sufficiently with a neutral
cleaning agent solution (approximately 2%), squeeze the cloth out, and then wipe the sur-
face.
• Materials such as rubber, vinyl, or tape that are attached to the Unit will leave stains if left
for a long time. If such material is attached to the Unit, remove when cleaning.
Note
Never use benzene, thinner, or other volatile solvents, or chemical cloths to clean the PT.
@ Inspection Methods
Inspect the PT once every six to twelve months. Shorten the interval between inspections
when using the PT in extreme conditions, such as under high temperatures, high humidity, or
environments subject to large quantities of dust.
