11. Cleaning and Simple Troubleshooting
11.1 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.
11.2 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.
11.3 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.
11.4 Simple Troubleshooting
If the display fails or the performance changes dramatically, check the display in
accordance with the following instructions. Remember to check the peripherals to pinpoint
the source of the failure. If the display still fails to perform as expected, contact the dealer
for assistance.
