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. 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 a soft, lint-free cloth.
