Troubleshooting
Introduction
This chapter includes instructions on cleaning and storing the device, and provides troubleshooting solutions
for potential problems during operation.
Maintaining the Device
For trouble-free service, observe the following tips when using the device:
• In order to avoid scratching the screen, use the supplied stylus or plastic-tipped pens intended for use with
a touch-sensitive screen. Never use an actual pen or pencil or other sharp object on the surface of the
device screen.
• The touch-sensitive screen of the device is glass. Do not drop the device or subject it to strong impact.
• Protect the device from temperature extremes. Do not leave it on the dashboard of a car on a hot day, and
keep it away from heat sources.
• Do not store the device in any location that is dusty, damp, or wet.
• Use a soft lens cloth to clean the device. If the surface of the device screen becomes soiled, clean it with a
soft cloth moistened with an approved cleanser. For a list of approved cleansers, see Approved Cleanser
Active Ingredients on page 181.
• Periodically replace the rechargeable battery to ensure maximum battery life and product performance.
Battery life depends on individual usage patterns.
Display Best Practices
Image Retention
Image retention may occur when a static image continuously displays for extended periods of time. A user may
see a faint remnant of the image even after a new image displays. To prevent image retention:
• set the display to turn off after a few minutes of idle time.
• rotate background images on a periodic basis.
• turn off the display when the device in not in use.
