CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE COVER (OR BACK).
ATTENTION: AFIN DEVITER UN CHOC ELECTRIQUE, ET LES CONSEQUENCES GRAVES QUI
POURRAIENT EN RESULTER, TENTEZ PAS D'OUVRIR L'APPAREIL ET DE TOUCHER AUX
COMPOSANTS INTERNES SANS LA PRESENCE D'UNE SERVICE PERSONNEL.
WARNING: TO REDUCE THE RISK OF FIRE OR ELECTRIC
SHOCK, DO NOT EXPOSE THIS UNIT TO RAIN OR MOISTURE.
The graphic symbol of a lightning flash with an arrow point within a tri-
angle signifies that there is dangerous voltage within the unit and it
poses a hazard to anyone removing the cover to gain access to the
interior of the unit. Only qualified service personnel should
make any such attempt.
The graphic symbol of an exclamation point within an equilateral trian-
gle warns a user of the device that it is necessary to refer to the
instruction manual and its warnings for proper operation of the unit.
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 man-
ufacturer or sold with the unit. Any mounting of the device on a
wall or ceiling should follow the maufacturer's instructions and
should use a mounting accessory recommended by the manu-
facturer.
An appliance and cart combination should be moved with care. Quick stops,
excessive force and uneven surfaces may cause the appliance and cart combi-
nation to overturn.
Read and follow all the safety and operating instructions before connecting or
using this unit. Retain this notice and the owner's manual for future reference.
All warnings on the unit and in it's 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 pif laced in a
built-in installation, such as a bookcase or cabinet, that may impede the flow of
air through the ventilation openings, there should be at least 20cm (8 in.) of free
space behind the unit.
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:
(1) The power cord or the plug has been damaged; or
(2) Objects have fallen, or liquid has been spilled into the unit; or
(3) The unit has been exposed to rain or liquids of any kind; or
(4) The unit does not appear to operate normally or exhibits a marked change
in performance; or
(5) 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 shop's
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. 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.
2
(1) Use No. 10 AWG (5.3mm ) copper, No. 8 AWG (8.4mm
2
17 AWG (1.0mm ) copper-clad steel or bronze wire, or larger, as a ground wire.
(2) Secure antenna lead-in and ground wires to house with stand-off
insulators spaced from 4-6 feet (1.22 – 1.83 m) apart.
(3) Mount antenna discharge unit as close as possible to where lead-in
enters house.
(4) Use jumper wire not smaller than No.6 AWG (13.3mm
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 installer's attention to Article 820-22 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.
