DO
Dust the screen and cabinet with a soft cloth.
Clean the screen with a soft cloth moistened with warm water. Dry with a soft cloth. (A
mild soap may be used if the screen is extremely dirty.)
Place the TV and remote control away from extreme heat, humidity and extremely dusty
places.
Remove the plug from the wall outlet if your television will not be used for a long period
of time, for instance, when you go on vacation
DO NOT
Do not clean your screen or cabinet with strong cleaners, polishes or a chemically
treated cloth.
Do not place rubber or vinyl products or cellophane tape on your set.
Do not touch the screen too often.
Do not subject the Remote Control to shocks such as dropping it on the floor, etc.
Physical damage to the precision parts may result.
Avoid placing the Remote Control in a high humidity place or getting it wet. Don't leave it
on or near a heater. Excessive heat or moisture may cause the unit to cease operation.
When the batteries run down, remote control operation will become erratic or possibly
stop altogether.
Replace the old batteries with fresh "AA" size batteries.
Exposure of the viewing screen to prolonged direct sunlight or heat may cause the
screen to permanently warp, resulting in a distorted picture.
