Cleaning the Display
Keep fingers and rough or sharp objects away from the display. If the glass becomes soiled or
smudged, clean only with a standard household cleaner such as Windex
®
without vinegar or use
Isopropyl Alcohol. Do not use paper towels or harsh-chemical-based cleaning fluids since they
may result in damage to the glass surface. Use a clean, damp, lint-free cloth. Do not scrub optical
surfaces. If possible, clean only those areas which are soiled. Lint/particulates can be removed
with clean, filtered canned air.
Disabling the Touchscreen
The touchscreen can be disabled, if desired. For more information, please refer to “Disabling the
Touchscreen” in the “VX3X Reference Guide”.
Calibrating the Touchscreen
Although the touch screen is installed and calibrated at the factory, users may make adjustments to
it. To calibrate the touchscreen, select Start | Settings and double tap the Stylus icon.
Figure 33 Touchscreen Calibration, Calibration Targets
The calibration utility displays a cross on the screen. Touch the center of the cross with the stylus
and hold for a few seconds. Release and repeat with the next cross. After all locations have been
touched, either press <Enter> or click the Calibration button.
Touchscreen Protective Film
LXE offers a replaceable touchscreen protective film to protect the touchscreen when the VX3X
is used in an abrasive environment. Installation and removal instructions can be found earlier in
this guide.
