READ BEFORE OPERATING EQUIPMENT
This product was designed and manufactured to meet strict

stallation and operation precautions which you should be
particularly aware of.
1. Read Instructions — All the safety and operating in-
structions should be read before the appliance is oper-
ated.
2. Retain Instructions — The safety and operating instruc-
tions should be retained for future reference.
3. Heed Warnings — All warnings on the appliance and in
the operating instructions should be adhered to.
4. Follow Instructions — All operating and use instruc-
tions should be followed.
5. Water and Moisture — The appliance should not be
used near water — for example, near a bathtub, wash-
bowl, kitchen sink, laundry tub, in a wet basement, or
near a swimming pool, etc.
6. Carts and Stands — The appliance should be used
only with a cart or stand that is recommended by the
manufacturer.
7. An appliance and cart combination should be moved
with care. Quick stops, excessive force, and uneven
surfaces may cause the appliance and cart combina-
tion to overturn.
8. Wall or Ceiling Mounting — The appliance should be
mounted to a wall or ceiling only as recommended by
the manufacturer.
9. 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.
10. Heat — The appliance should be situated away from
heat sources such as radiators, heat registers, stoves,
or other appliances (including amplifiers) that produce
heat.
11. 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.
12. Grounding or Polarization — The precautions that
should be taken so that the grounding or polarization
means of an appliance is not defeated.

13. 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
appliance.
14. Cleaning — The appliance should be cleaned only as
recommended by the manufacturer.
15. Power Lines— An outdoor antenna should be located
away from power lines.
16. 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. See Fig. 1.
17. Nonuse Periods — The power cord of the appliance
should be unplugged from the outlet when left unused
for a long period of time.
18. Object and Liquid Entry — Care should be taken so that
objects do not fall and liquids are not spilled into the en-
closure through openings.
19. Damage Requiring Service — The appliance should be
serviced by qualified service personnel when:
A. The power-supply cord or the plug has been dam-
aged; or
B. Objects have fallen, or liquid has spilled into the ap-
pliance; or
C. The appliance has been exposed to rain; or
D. The appliance does not appear to operate normally
or exhibits a marked change in performance; or
E. The appliance has been dropped, or the enclosure
damaged.
20. Servicing — The user should not attempt to service the
appliance beyond that described in the operating in-
structions. All other servicing should be referred to
qualified service personnel.
