Maintenance and 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:
• 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.
• Periodically replace the rechargeable battery to ensure maximum battery life and product performance.
Battery life depends on individual usage patterns.
Battery Safety Guidelines
• The area in which the units are charged should be clear of debris and combustible materials or
chemicals. Particular care should be taken where the device is charged in a non commercial
environment.
• Follow battery usage, storage, and charging guidelines found in this guide.
• Improper battery use may result in a fire, explosion, or other hazard.
• To charge the mobile device battery, the ambient battery and charger temperatures must be between
+32ºF and +104ºF (0ºC and +40ºC).
• Do not use incompatible batteries and chargers, including non-Zebra batteries and chargers. Use of an
incompatible battery or charger may present a risk of fire, explosion, leakage, or other hazard. If you
have any questions about the compatibility of a battery or a charger, contact the Global Customer
Support Center.
