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 base-
ment, 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 manufacturer.
●
An appliance and cart combination should be moved with care.
Quick stops, excessive force, and uneven surfaces may cause
the appliance 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 operating 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 receptacles, and the
point where they exit from the appliance.
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, grounding of the lead-in wire to
an antenna discharge unit, size of grounding conductors, location of antenna-
discharge unit, connection to grounding electrodes, and requirements for the
grounding electrode.
