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.

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.

The appliance should be used only with a cart or stand that is
recommended by themanufacturer.

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.

This equipment is not designed for use mounted on a wall or a
ceiling.

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 bookcase or cabinet that may
impede the flow of air through the ventilation openings.

The appliance should be situated away from heat sources
such as radiators, heat registers, stoves, or other appliances
(including amplifiers) that produce heat.

The appliance should be connected to a power supply only of
the type described in the operating instructions or as marked
on the appliance.

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

The appliance should be cleaned only as recommended by
themanufacturer.

The power cord of the appliance should be unplugged from the
outlet when left unused for a long period of time.

Care should be taken so that objects do not fall and liquids are
not spilled into the enclosure through openings.

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.

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 is

damaged.

(APPLIES TO TUNER AND RECEIVERS ONLY)

An outdoor antenna should be located away from power lines.

(APPLIES TO TUNER AND RECEIVERS ONLY)

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 Figure.
a) Use No. 10 AWG (5.3 mm ) copper, No. 8 AWG (8.4 mm )

aluminum, No. 17 AWG (1.0 mm ) copper-clad steel or
bronze wire, or larger, as a ground wire.

b) Secure antenna lead-in and ground wires to house with

stand-off insulators spaced from 4-6 feet (1.22-1.83 m)
apart.

c) Mount antenna discharge unit as close as possible to where

lead-in enters house.

d) Use jumper wire not smaller than No.6 AWG (13.3 mm )

copper, or the equivalent, when a separate antenna-
grounding electrode is used. See NEC Section 810-21(j).
