REMOVE COVER (OR BACK). NO USER SERVICEABLE PARTS
INSIDE.
REFER SERVICING TO QUALIFIED SERVICE PERSONNEL.
THIS SYMBOL IS INTENDED TO ALERT THE USER TO THE
PRESENCE OF UNINSULTED "DANGEROUS VOLTAGE"
WITHIN THE PRODUCT S ENCLOSURE THAT MAY BE
SUFFICIENT MAGNITUDE TO CONSTITUTE A RISK OF

Important Safety Instructions
- All the safety and operating instructions should be read before
the appliance is operated.
- The safety and operating instructions should be retained for
future reference.
- All warnings on the appliance and in the operating instructions
should be adhered to.
- All operating and use instructions should be followed.
1. 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,
and the like.
2. Carts and Stands - The appliance
should be used only with a cart or
stand that is recommended by th
manufacturer.
3. 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.
4. Wall or Ceiling Mounting - The appli-
ance should be mounted to a wall or
ceiling only as recommended by the manufacturer.
5. 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.
6. Heat - The appliance should be situated away from heat
sources such as radiators, heat registers, stoves, or other
appliances (including amplifiers) that produce heat.
7. 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.
8. Grounding or Polarization - The precautions that should be
taken so that the grounding or polarization means of an
appliance is not defeated.
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.Protective Attachment Plug - If the appliance is equipped with
an attachment plug having overload protection. This is a
safety feature. See Instruction Manual for replacement or
resetting of protective device. If replacement of the plug is
required, be sure the service technician has used a
replacement plug specified by the manufacturer that has the
same overload protection as the original plug.
11.Cleaning - The appliance should be cleaned only as
recommended by the manufacturer.
12.Power Lines - An outdoor antenna should be located away
from power lines.

Safety Precautions
13.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. Article 810 of the National
Electrical Code, ANSI/NFPA 70, provides information with
regard 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,location of antenna-
discharge unit, connection to grounding electrodes and
requirements for the grounding electrode. See Figure 1.
14.Non-use Periods - The power cord of the appliance should be
unplugged from the outlet when left unused for a long period
of time.
15.Object and Liquid Entry - Care should be taken so that objects
do not fall and liquids are not spilled into the enclosure through
openings.
16.Damage Requiring Service - The appliance should be
serviced by qualified service personnel when:
a) The power-supply cord or the plug has been damaged; or
b) Objects have fallen, or liquid has been spilled into the
appliance; 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.
17.Servicing - The user should not attempt to service the
appliance beyond that described in the operating instructions.
All other servicing should be referred to qualified service
personnel.
