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

dangerous voltage within the product’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 manufacturer’s 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 owners

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

shops 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.

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 installers 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.

2. “Where the mains plug or an appliance coupler is used as the

     disconnect device, the disconnection device shall remain readily 

     operable.”

3. “1A fuse is used to US market, voltage will be set to 115V before
