IMPORTANT SAFEGUARDS
CAUTION
All the safety and operating instructions should be read
before the appliance is operated, and should be retained
for future reference.
Electrical energy can perform many useful functions. This
unit has been engineered and manufactured to assure
your personal safety. Improper use can result in potential
electrical shock or fire hazards. In order not to defeat the
safeguards, observe the following basic rules for its
installation, use and servicing.
1 Heed Warnings - All warnings on the appliance and in
the operating instructions should be adhered to.
2 Follow Instructions - All operating and use instructions
should be followed.
3 Water and Moisture - The appliance 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, etc.
4 Carts and Stands - The appliance should be used only
with a cart or stand that is recommended by the manu-
facturer.
●
An appliance and cart combination
should be moved with care.
Quick stops, excessive force, and un-
even surfaces may cause the appli-
ance and cart combination to overturn.
5 Wall or Ceiling Mounting - The appliance should be
mounted to a wall or ceiling only as recommended by
the manufacturer.
6 Ventilation - The appliance should be situated so that
its location or position does not interfere with its proper
ventilation. For example, the appliance 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.
7 Heat - The appliance should be situated away from heat
sources such as radiators, heat registers, stoves, or
other appliances (including amplifiers) that produce
heat.
8 Power Sources - The appliance should be connected
to a power supply only of the type described in the op-
erating instructions or as marked on the appliance.
9 Power-Cord Protection - Power-supply cords should be
routed so that they are not likely to be walked on or
pinched by items placed upon or against them, paying
particular attention to cords at plugs, convenience re-
ceptacles, and the point where they exit from the appli-
ance.
10 Do not use liquid cleaners or aerosol cleaners. Use a
damp cloth for cleaning.
11 Power Lines - An outdoor antenna should be located
away from power lines.
12 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. Section 810
of the National Electrical Code, ANSI/NFPA No. 70-
1984, provides information with respect to proper
grounding of the mast and supporting structure, ground-
ing of the lead-in wire to an antenna discharge unit,
size of grounding conductors, location of antenna-dis-
charge unit, connection to grounding electrodes, and
requirements for the grounding electrode.
