A plastic stylus is mounted on the rear panel for the convenience of signature capture or other touch
screen operations.
NOTE:
To prevent touch screen overlay damage, do not contact the exposed polarizer with
anything harder than a device stylus. To clean dust off the display surface, gently wipe it
with cotton, chamois, or any other soft material.
To decrease the wear of the touch screen overlay, specify your software application
architecture to use device keys to enable the most commonly used application functions.
