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 arrow point within a triangle 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
personnel should make any such attempt.
The graphic symbol of an exclamation point within an equilateral triangle warns
the 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 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 owner's manual for future reference.
All warnings on the unit and 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 open-
ings.
The unit should be situated away 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 fre-
quency 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. RE-
FER SERVICING TO QUALIFIED SERVICE PERSONNEL.
Upon compIetion 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 guar-
antee 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 or 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 or the National Electrical Code ANSl/NFPA NO.
70-1984, provides information with respect to proper grounding of the mast and support-
ing structure, grounding of the lead-in wire to an antenna discharge unit, size of ground-
ing conductors, location of antenna discharge unit, connection to grounding electrodes
and requirements for the grounding electrode.

(1) Use No.10 AWG (5.3mm ) copper, No. 8 AWG (8.4mm
2
(1.Omm ) 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 - 1.83m) 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
when a separate antenna-grounding electrode is used. See NEC Section 810-21 (j).

NOTE TO CATV SYSTEM INSTALLER: This reminder is provided to call the CATV
installer's attention to Article 820-22 of the National Electrical Code that provides guide-
lines for proper grounding and, in particular, specifies that the ground cable ground shall
be connected to the grounding system of the building, as close as possible to the point of
cable entry as practical.
