Cleaning the Unit
The c320 is constructed of high quality materials and does not
require user maintenance other than cleaning. Clean the unit’s
outer casing (except for the touchscreen) using a cloth dampened
with a mild detergent solution and then wipe dry. Avoid chemical
cleaners and solvents that may damage plastic components.
Cleaning the Touchscreen
The touchscreen is intended primarily for finger operation.
Although a PDA stylus may also be used to operate the
touchscreen, never attempt this while operating a vehicle. Never
use a hard or sharp object to operate the touchscreen or damage
may result. Clean the touchscreen using a soft, clean, lint-free
cloth. Water, isopropyl alcohol, or eyeglass cleaner can be used
if needed. If these are used, apply the liquid to the cloth and then
gently wipe the touchscreen with the moistened cloth.
Storing your c320
Do not store the c320 where prolonged exposure to temperature
extremes may occur (such as in the trunk of a car), as permanent
damage may result.
Your c320 is not Waterproof
Do not position the c320 in places where it may be exposed to
water. Contact with water can cause this unit to malfunction.
Calibrating the Touchscreen
In the rare event you sense that the touchscreen is not responding
properly to touch commands, you can calibrate it. Press and hold
the
Power
button until the Calibration screen appears. Follow the
on-screen instructions.
