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 cabinet
with the cloth. Use a clean cloth to dry the cabinet.
Cleaning the TV screen
Clean the screen with a soft, lint-free cloth.
