Maintenance and Troubleshooting
This chapter includes instructions on cleaning and storing the device, and provides troubleshooting solutions for
potential problems during operation.
Maintaining the ET1
For trouble-free service, observe the following tips when using the ET1:
• Do not scratch the screen of the ET1. When working with the ET1, use a finger or approved stylus or pen intended
for use with a capacitive touch-sensitive screen. Never use an actual pen or pencil or other sharp object on the
surface of the ET1 screen.
• The touch-sensitive screen of the ET1 is glass. Do not to drop the ET1 or subject it to strong impact.
• Protect the ET1 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 or use the ET1 in any location that is dusty, damp, or wet.
• Use a soft lens cloth to clean the ET1. If the surface of the ET1 screen becomes soiled, clean it with a soft cloth
moistened with a diluted window-cleaning solution.
• 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 battery and charger temperatures must be between +32 ºF and +104 ºF (0
ºC and +40 ºC)
• Do not use incompatible 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.
• For devices that utilize a USB port as a charging source, the device shall only be connected to products that bear
the USB-IF logo or have completed the USB-IF compliance program.
• To enable authentication of an approved battery, as required by IEEE1725 clause 10.2.1, all batteries will carry a
hologram. Do not fit any battery without checking it has the authentication hologram.
• Do not disassemble or open, crush, bend or deform, puncture, or shred.
• Severe impact from dropping any battery-operated device on a hard surface could cause the battery to overheat.
• Do not short circuit a battery or allow metallic or conductive objects to contact the battery terminals.
• Do not modify or remanufacture, attempt to insert foreign objects into the battery, immerse or expose to water or
other liquids, or expose to fire, explosion, or other hazard.
