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 func-
tions. This unit has been engineered and manufac-
tured to assure your personal safety. Improper use
can result in potential electrical shock or fire haz-
ards. 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 ad-
hered to.
2
Follow Instructions - All operating and use instruc-
tions should be followed.
3
Water and Moisture - The appliance should not
be used near water - for example, near a bath-
tub, 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 manufacturer.
An appliance and cart combina-
tion should be moved with care.
Quick stops, excessive force,
and uneven surfaces may cause
the appliance and cart combina-
tion to overturn.
5
Wall or Ceiling Mounting - The appliance should
be mounted to a wall or ceiling only as recom-
mended 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 regis-
ters, stoves, or other appliances (including am-
plifiers) that produce heat.
8
Power Sources - The appliance should be con-
nected to a power supply only of the type de-
scribed 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 an-
tenna 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 Na-
tional 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 dis-
charge unit, size of grounding conductors, lo-
cation of antenna-discharge unit, connection to
grounding electrodes, and requirements for the
grounding electrode.
