Chapter 4 - Maintenance and Troubleshooting
4.1 - Maintenance
Important
1. Make sure that the power cable is removed from the socket before cleaning the display.
2. Do not use volatile solvent (such as toluene, rosin and alcohol) to clean the display. Such chemicals may
damage the housing, screen glass and remote control, and cause the paint to peel.
Cleaning the Housing and the Remote Control
1. Use a soft cotton cloth for cleaning.
2. If the housing or remote control is seriously contaminated, use a soft cloth moistened with diluted neutral
cleaner to clean the display. Wring water out of the cloth before cleaning to prevent water from
penetrating into the housing. Wipe the display with a dry cloth after cleaning.
Cleaning the Screen
1. Use a soft cotton cloth to gently clean the screen.
2. The screen glass is very fragile. Do not scrape it with any sharp object. Do not press or tap the screen to
avoid cracking. When the screen is seriously contaminated, use a soft cloth moistened with diluted neutral
cleaner to clean the display. Wring water out of the cloth before cleaning to prevent water from
penetrating into the housing. Wipe the display with a dry cloth after cleaning.
