Safety Information
Caring for your unit
Case vent hole
A Gore-Tex membrane is used at the vent hole to equalize the atmospheric pressure within the unit
and to prevent dust, water, and so on. from entering. The vent must remain clear of any
obstruction. Damage to the touchscreen will occur if the vent is covered. Covering the vent with
stickers and labels may void the warranty.
Cleaning the unit
Use a soft, dampened cloth with either water or a diluted mild detergent. If a mild detergent is used,
ensure all soap residue is removed. Do not use any chemical cleaners and do not put the unit in the
dishwasher.
Care of the touchscreen
Use only the included stylus or other devices specifically designed for use with touchscreens.
The use of ballpoint pens, nails or other sharp objects to operate the touchscreen will scratch
and/or damage the unit. Keep the touchscreen clean by gently wiping the display, using a soft,
dampened cloth with either clean water or glass cleaner.
Do not use abrasive cleaners directly on the display. Doing so may void your warranty. Use the
screen protectors included with the unit to keep the touchscreen clean and protected, following the
instructions provided on the screen protector package.
Mechanical shock
The unit is designed to resist damage for drops up to 4 ft (1.22 meters). However, you should
protect the display from impact, pressure, or abrasive substances that can scratch it or crack it. The
unit should not be dropped unnecessarily.
