TELEVISION EQUIPMENT.
Do not use this unit near water; for example, near a bath tub,
washbowl, kitchen sink, laundry tub, in a wet basement or near a
swimming pool.
The unit should be installed so that its location or position does not
interfere with its proper ventilation. For example, it should not be
situated on a bed, sofa, rug or similar surface that may block the
ventilation openings; or placed in a built-in installation, such as a
bookcase or cabinet, that may impede the flow of air through its
ventilation openings.
The unit should be situated from heat sources such as radiators,
heat registers, stoves or other devices (including amplifiers) that
produce heat.
The unit should be connected to a power supply outlet only of the
voltage and frequency marked on its rear panel.
The power supply cord should be routed so that it is not likely to be
walked on or pinched, especially near the plug, convenience
receptacles, or where the cord exits from the unit.
Unplug the unit from the wall outlet before cleaning. Never use
benzine, thinner or other solvents for cleaning. Use only a soft
damp cloth.
The power supply cord of the unit should be unplugged from the
wall outlet when it is to be unused for a long period of time.
Care should be taken so that objects do not fall, and liquids are not
spilled into the enclosure through any openings.
This unit should be serviced by qualified service personnel when:
