The Display

The Marathon display is capable of supporting WVGA graphics modes (800x480). The display covering is designed to resist
stains. The touch screen allows signature capture and touch input. A display optimized for outdoor viewing is available.
The touch screen is a Resistive Panel with a scratch resistant finish that can detect touches by a stylus, and translate them
into computer commands. In effect, it simulates a computer mouse. Only Delrin or plastic styluses should be used. An extra or
replacement stylus may be ordered.
Note: Always use the point of the stylus for tapping or making strokes on the display. Never use an actual pen, pencil or
sharp object to write on the touch screen.

Adjust Display Brightness

The display can be lightened or darkened by using the Fn key and the keypad:
1. Hold the Fn key down for a few seconds until the Fn key remains illuminated (sticky).
2. Press the 9 (brightness up) key to brighten the display.
3. Press the 3 (brightness down) key to darken the display.
The display brightness and darkness have nine levels. The display levels are managed by the Windows operating system. The
Fn key active sticky mode takes precedence if the NumLck key is illuminated (sticky) during this process.

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.
