The monitor has been designed to provide years of trouble-free operation
even in the harshest environments. However, occasionally you need to
perform routine maintenance on some of the monitor’s components.
This chapter provides instructions on monitor maintenance, as well as
steps for troubleshooting problems that may occur in operation.
Cleaning the Screen
Occasionally, you may need to clean the monitor’s screen. Clean the
screen using warm, soapy water and a cloth. You can also use any non-
abrasive cleaner. See Faceplate Chemical Resistance on page A-4, for a list
of substances the screen can resist with no visible effect.
Do not use any harsh material or powder, such as steel wool or abrasive
cleansers, to clean the screen surface. The surface is sensitive to scraping,
sharp blows, or punctures. Therefore, keep screwdrivers or other sharp
objects away from the screen surface.
Warning
Do not clean the unit while it is running. Turn off the
monitor before cleaning it in order to avoid inadvertently
activating the touchscreen.
Recalibrating the Touchscreen
Your touchscreen was calibrated by Parker before your monitor was
shipped. However, you may need to recalibrate the touchscreen when you
begin using the monitor for the first time, when you connect the monitor to
a new computer, or whenever the cursor location and the place on the
screen where the user touches do not match. See Step 2: Calibrating the
Touchscreen in Chapter 3, for instructions on how to recalibrate your
touchscreen.
