Warning: To reduce the risk of fire or electric shock, do not
expose this unit to rain or moisture.

The lightning flash with an arrowhead symbol within an equilateral
triangle, is intended to alert the user to the presence of uninsulated
ìdangerous voltageî within the productí s enclosure that may be of
sufficient magnitude to constitute a risk of electric shock to persons.

The exclamation point within an equilateral triangle is intended to
alert the user to the presence of important operating and
maintenance (servicing) instructions in the literature accompanying
the product.

Do not place this unit on an unstable cart, stand or tripod, bracket
or table. The unit may fall, causing serious injury to a child or adult
and serious damage to the unit. Use only with a cart, stand, tripod,
bracket or table recommended by the manufacturer or sold with
the unit. Any mounting of the device on a wall or ceiling should
follow the manufacturerís instructions and should use a mounting
accessory 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.

Read and follow all the safety and operating instructions before
connecting or using this unit. Retain this notice and the ownerís
manual for future reference.

All warnings on the unit and in its operating instructions should be
adhered to.

Do not use this unit near water; for example, near a bath tub,
washbowl, kitchen sink, laundry tub, in a wet basement or near a
swimming pool.

The unit should be installed so that its location or position does not
interfere with its proper ventilation. For example, it 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 its
ventilation openings.

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

The unit should be connected to a power supply outlet only of the
voltage and frequency marked on its rear panel.

The power supply cord should be routed so that it is not likely to be
walked on or pinched, especially near the plug, convenience
receptacles, or where the cord exits from the unit.

Unplug the unit from the wall outlet before cleaning. Never use
benzine, thinner or other solvents for cleaning. Use only a soft
damp cloth.

The power supply cord of the unit should be unplugged from the
wall outlet when  it is to be 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 any openings.

This unit should be serviced by qualified service personnel when:

A. The power cord or the plug has been damaged; or
B. Objects have fallen, or liquid has been spilled into the unit; or
C. The unit has been exposed to rain or liquids of any kind; or
D. The unit does not appear to operate normally or exhibits a

marked change in performance; or

E. The device has been dropped or the enclosure damaged.

DO NOT ATTEMPT SERVICING OF THIS UNIT

YOURSELF. REFER SERVICING TO QUALIFIED

SERVICE PERSONNEL

Upon completion of any servicing or repairs, request the service
shopís assurance that only Factory Authorized Replacement Parts
with the same characteristics as the original parts have been used,
and that the routine safety  checks have been performed to
guarantee that the equipment is in safe operating condition.
REPLACEMENT WITH UNAUTHORIZED PARTS MAY RESULT IN FIRE,
ELECTRIC SHOCK OR OTHER HAZARDS.

CAUTION

TO PREVENT ELECTRIC SHOCK, MATCH WIDE BLADE OF
PLUG TO WIDE SLOT FULLY INSERT.

If an indoor antenna is used (either built into the set or installed
separately), never allow any part of the antenna to touch the metal
parts of other electrical appliances such as a lamp, TV set etc.

CAUTION

POWER LINES

Any outdoor antenna must be located away from all power lines.

OUTDOOR ANTENNA GROUNDING

If an outside antenna is connected to your tuner or tuner-
preamplifier, 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 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.

a. Use No. 10 AWG (5.3mm2) copper, No. 8 AWG (8.4mm2)

aluminium, No. 17 AWG (1.0mm2) 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 (13.3mm2) copper,

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

EXAMPLE OF ANTENNA GROUNDING AS PER NATIONAL ELECTRICAL
CODE INSTRUCTIONS CONTAINED IN ARTICLE 810 - RADIO AND
TELEVISION EQUIPMENT.

NOTE TO CATV SYSTEM INSTALLER:

This reminder is

provided to call the CATV system installerís attention to
Article 820-40 of the National Electrical Code that provides
guidelines for proper grounding and, in particular, specifies
that the ground cable ground shall be connected to the
grounding system of the building, as close to the point of
cable entry as practical.
