User Manual Sony KDL-46XBR8 46" Class Bravia Xbr Series Lcd Television

The TV is designed with slots and openings for necessary ventilation. To ensure reliable operation and to protect it from overheating, these slots and openings must never be blocked or covered. As a general guideline, the rear of the TV should be 2 to 6 inches away from the wall and the sides of the TV should have about 4 inches of ventilation space.

A High Definition TV with 1080p resolution is composed of two million pixels (1920 x 1080), while a 4K TV (aka Ultra High Definition) has over eight million pixels (3840 x 2160). Therefore, 4K has around four times more resolution than 1080p and produces a clearer picture.

Follow these steps to ensure that you are maximizing the capability of the supplied remote control:
Install fresh batteries into the remote.
Make sure nothing is blocking the Infrared (IR) sensor on the TV. Some locations or TV stand designs can interfere with the IR signal from the remote control. Glass enclosures, as well as fluorescent or halogen lights, may prevent the IR signal from reaching the TV.
NOTE: While Sony does not manufacture or support the use of IR repeaters or IR extenders, these type of devices may be the solution when installing the device in a large room or custom home theater installations. Contact your home theater installer or visit your local retailer for additional information.

Under normal or moderate use, the batteries in a remote control should last up to 3-6 months.
IMPORTANT: If you do not use the remote control for an extended period of time, remove the batteries to avoid possible damage from battery leakage.
NOTES:
Do not use a fresh battery with an old one.
Do not use different types or brands of batteries together.
