Display

The display is a thin-film transistor display capable of supporting WVGA graphics modes. Display size is 800 x 480 pixels. The
display covering is designed to resist stains. The touchscreen allows signature capture and touch input. The display supports
screen blanking to eliminate driver distraction when the vehicle is in motion.

Touchscreen

The touchscreen 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. A right
mouse click is simulated by touching and holding the screen for the appropriate time interval.
Always use the point of the stylus for tapping or making strokes on the display. Never use an actual pen, pencil, sharp or
abrasive object to write on the touchscreen.
An extra or replacement stylus may be ordered.
A replaceable touchscreen protective film is available when the Thor VM1 is used in an abrasive environment. Contact your
representative for availability.
Note: If the touch screen is disabled or looses calibration on a Thor VM1 with the 12 key keypad, you must
use a USB mouse or keyboard attached to the Thor VM1 to access the control panel ro re-enable or
recalibrate the touch screen.
