NEVERplug your TV into an outlet that is controlled by a wall switch.• Turn off the TV and/or device(s) before you connect or disconnect any cables.• Make sure all antennas and cables are properly grounded. Refer to the Important Safety Instructions atthe beginning of the User's Guide.Protect Against Power Surges• Don’t block ventilation holes on any of the devices. Arrange the devices so that air can circulate freely.• Don’t stack devices.• If you place devices in a stand, make sure you allow adequate ventilation.• If you connect an audio receiver or amplifier, place it on the top shelf so the heated air from it won’t flowaround other devices.Protect Devices from Overheating• Insert each cable firmly into the designated jack.• If you place devices above the TV, route all cables down the side of the back of the TV instead of straightdown the middle.• If your antenna uses 300-ohm twin lead cables, do not coil the cables. Also, keep the twin lead cablesaway from audio/video cables.Position Cables Properly to Avoid Audio InterferenceDon’t place the TV where sunlight or room lighting will be directed toward the screen.
