Figure 2-12 Touch Screen Display
The MX5 Touch Screen Display is an Active Color LCD unit capable of supporting QVGA
graphics modes. Display size is 320 x 240 pixels in portrait orientation. The display covering is
designed to resist stains. The touch screen allows signature capture and touch input. A pen stylus
is included. The touch screen responds to an actuation force (touch) of 4 oz. of pressure (or
greater).
The color display has a CCFL (Cold-Cathode Fluorescent Lighting) front light. When the unit is
in Suspend mode, the reflective 256 color display appears to have a greenish hue.
The display is automatically turned off when the MX5 enters the Suspend state.
Display and Keypad Backlight Timer
When the Backlight timer expires the display and keypad backlight is turned off. The default
value for the battery power and AC timer is 30 seconds.
See the section titled "Set the Display Backlight Timer" in Chapter 1 “Introduction”, section titled
"Quick Start."
When the display wakes up, the Backlight timers will begin the countdown again.
Cleaning the Glass Display/Scanner Aperture
Keep fingers and rough or sharp objects away from the scan aperture and display. If the glass
becomes soiled or smudged, clean only with a standard household cleaner such as Windex(R)
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.
