Maintaining the ES400
For trouble-free service, observe the following tips when using the ES400:
• Do not scratch the screen of the ES400. When working with the ES400, 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 ES400 screen.

• The touch-sensitive screen of the ES400 is polycarbonate. Do not to drop the ES400 or subject it to strong
impact.
• Protect the ES400 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 ES400 in any location that is dusty, damp or wet.
• Use a soft lens cloth to clean the ES400. If the surface of the ES400 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.
