Before using this unit, be sure to read applicable items of the
operating
instructions and these safety suggestions
carefully.
Afterwards keep them handy for future reference. Take special
care to follow the warnings indicated on the unit itself as well as in
the operating instructions.
1. Water and Moisture -- The unit should not be used near
water -- for example,
near a bathtub, washbowl,
kitchen
sink, laundry tub, in a wet basement, or near a swimming
pool, and the like.
ad
Object and Liquid Entry -- Care should be taken so that
objects do not fall and liquids are not spilled into the
enclosure through openings.
3. Ventilation -- The unit should be situated so that its
location or position does
not interfere with its proper
ventilation. For example, the unit 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 the ventilation openings.
4. Heat -- The unit should be situated away from heat sources
such as radiators, heat registers, stoves, or other units that
produce heat.
a
Polarization -- If the unit is equipped with a polarized AC
power plug (a plug having one blade wider than the other),
that plug will fit into the AC outlet only one way. This is a
safety feature. If you are unable to insert the plug fully into
the outlet, try reversing the plug. If the plug should still fail to
fit, contact your electrician to replace your obsolete outlet.
Do not defeat the safety purpose of the polarized plug.
ad
with care. Quick stops, excessive force,
and cart combination to overturn.
9. wall or Ceiling Mounting
-- The unit should be
mounted to a wall or ceiling only as recommended by the
manufacturer.
10
Cleaning -- The unit should be cleaned only as rec-
ommended by the manufacturer.
11. Outdoor Antenna Grounding -- If an outside antenna
is connected to the receiver, be sure the antenna system is
grounded so as to provide some protection against voltage
surges and built-up static charges.
