Calibrating the Screen

To calibrate the screen so the cursor on the touch screen aligns with the tip of the stylus:

1. Remove the stylus from its holder on the side of the MC55.

2. Carefully press and briefly hold the tip of stylus on the center of each target that appears on the screen.

3. Repeat as the target moves around the screen, then tap the screen to continue.

Resetting the MC55

There are three reset functions, warm boot, cold boot and clean boot. A warm boot restarts the MC55 by

closing all running programs. A cold boot also restarts the MC55, and also initializes some drivers. Data saved

in flash memory or a memory card is not lost.

If the MC55 is not functioning properly, perform a warm boot first. If the MC55 still does not respond, perform a

cold boot.

Performing a Warm Boot

Hold down the red Power button for approximately five seconds. As soon as the MC55 starts to boot release

the Power button.
