Maintaining
• Do not use your TV in areas that are too hot or too
cold, because the cabinet may warp or the screen
may malfunction. Your TV works best in
temperatures that are comfortable to you.
• Storage temperatures are 32° to 122°F (0° to 50°C).
• Working temperatures are 41° to 104°F (5° to
40°C).
• Do not place your TV in direct sunlight or near a
heat source.
Cleaning the TV cabinet
Clean the cabinet with a soft, lint-free cloth. Do not
use the cleaning cloth that came with your TV to
clean the cabinet. If the cabinet is especially dirty,
moisten a soft, lint-free cloth in a weak detergent
solution, squeeze the excess moisture from the
cloth, then wipe the screen or cabinet with the
cloth. Use a clean cloth to dry the screen or cabinet.
Cleaning the TV screen
Clean the screen with the cleaning cloth or a soft,
lint-free cloth. Do not use the cleaning cloth to
clean other parts of your TV.
