LINE VOLTAGE SELECTOR SWITCH
Only multi-voltage models are provided with this
switch. U.S., Canadian, European, U.K., and Australian
models are not provided with this switch.
The line voltage selector switch is on the rear panel. Before
your model is shipped from the factory, this switch is set to
the power requirements of the destination. Check that it isset
properly before plugging the power cord into the AC outlet. If
the voltage is not properly set or if you move to an area where
the voltage requirements differ, adjust the selector switch as
follows.
1. Use a medium-size screwdriver.
2. Insert the screwdriver into the groove on the voltage seec-
tor, and adjust so that the tip of the arrow points to the
voltage value of your area.

READ INSTRUCTIONS — All the safety and
Operating instructions should be read before the
appliance is operated.
RETAIN INSTRUCTIONS — The operating instruc-
ttons should be retained for future reference.
HEED WARNING — All warnings on the appliance
and in the operating instructions should be
adhered to.
FOLLOW INSTRUCTIONS — All operating and use
instructions should be followed.
WATER AND MOISTURE — The appliance should
not be used near water — for example, near a
bathtub, washbow/l, kitchen sink, laundry tub, ina
wet basement, or near a swimming pool, etc.
LOCATION — The appliance should be installed in a
stable location.
WALL OR CEILING MOUNTING — The appliance
should not be mounted to a wail or ceiling.
VENTILATION — The appliance should be situated
so that its !ocation or position does not interfere
with its proper ventilation. For example, the ap-
pliance 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 the ventilation openings.
HEAT — The appliance should be situated away from
heat sources such as radiators, heat registers,
stoves, or other appliances (including amplifiers)
that produce heat.
POWER SOURCES —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-CORD PROTECTION — 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.
POLARIZATION — If your purchased product is
provided with a polarized power plug, please read
the following instructions. This product is
equipped with a polarized alternating current line
plug (a plug having one blade wider than the
other). This piug will fit into the power outlet only
one way. This is a safety feature. If you are unable
to insert the plug fully into the outlet, try reversing
the plug. If the plug should still fai! to fit, contact
your electrician to replace your obsolete outlet.
Do not defeat the safety purpose of the polarized
plug.
CLEANING — The appliance should be cleaned only
with a polishing cloth or a soft dry cloth. Never
clean with furniture wax, benzine, insecticides or
other volatile liquids since they may corrode the
cabinet.
IMPORTANT 1
The tightning flash with arrowhead, within an equi-
jateral triangle, is intended to alert the user of 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.
IMPORTANT 2
tf the apparatus is fitted with AC mains power out-
let(s), see REAR PANEL FACILITIES for convenient
connection of additional Hi-Fi component(s). Make
all connections to the AC outlet(s) and the signal
terminals first. Connect the plug to the wali socket
last, make sure that the power switch is off. Discon-
Nect the wall plug when the equipment is not in
(regular) use, e.g. when on vacation.

SAFETY INSTRUCTIONS
OUTDOOR ANTENNA GROUNDING — If an out-
side antenna is connected to the antenna termi-
nai, be sure the antenna system is grounded so as
to provide some protection against voltage surges
and built up static charges.
In the U.S.A. section 810 of the National Elec-
trical Code, ANS!I/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 elec-
trodes, and requirements for the grounding elec-
trode. See Fig. A.
Use No. 10 AWG (5.3mm?%) cop-
per. No. 8 AWG (8.4 mm?) alu-
minum, No. 17 AWG (1.0 mm?)
copperclad steel, bronze wire, or
larger as ground wire.
Secure antenna lead-in and
ground wires to house with
stand-off insulators spaced from
4 feet (1.22 meters) to 6 feet
(1.83 meters) apart.
Mount antenna discharge unit as
closely as possible to where lead-
in enters house.
Use jumper wire not smaller than
No.6 AWG (13.3 mm?) copper,
or the equivalent, when a sepa-
rate antenna-grounding electrode
is used.

POWER switch
When this switch is set to the on position, power is supplied to the
tuner’s main circuits. The POWER unit’s switch is geared to selec-
| ting the transformer’s secondary so that even in stand-by position,
| the unit's circuitry will work as long as the power cord is connected
’ to a power outlet. Disconnect the power cord from the power outlet
when you do not plan to use the unit for a jong period of time.
FM MONO switch
Normally, when receiving an FM stereo broadcast, leave this switch
OFF. If the broadcast station is distant, or if you are in a poor recep-
tion area, the input signals will be weak, and during stereo recep-
tion, noise will be prominent, making the broadcast difficult to hear.
in such a case, press ON this switch. The broadcast will be
reproduced in monaural, however noise will be reduced, enabling
NOTE: the broadcast to be heard more clearly.

HINTS FOR BETTER RECEPTION
EXTERNAL FM ANTENNA
The main advantage of FM over AM is the quality of the
broadcast signal. In order to benefit fully from the high signal
quality of FM broadcasts, it is recommended that a special-
purpose FM antenna be installed. In weak signal areas, a
multi-element (3 element, 5 element, 7 elerhent) antenna
should be used.
NOTE:
Consult your dealer as to the selection and actual installation of the
FM antenna.
FM ANTENNA CONNECTIONS
There are two ways of connecting the FM antenna to the
antenna input terminals: with a 300-ohm twin-lead feeder or
with a 75-ohm coaxial cable. If full justice is to be done to the
tuner’s performance, a 75-ohm coaxial cable is recommended
since itis more immune than the twin-lead feeder to noise and
interference from external sources. If an FM antenna has
already been erected outdoors, connect it, referring to the
figure.
GROUNDING
Grounding is recommended if reception of FM programs is im-
paired by noise. To ground, connect a thick polyvinyl wire to
the GND terminal and attach the other end to a metal water
pipe or grounding bar or wind it around a copper plate and
bury it.
NOTE:
Never connect a wire to a gas pipe for grounding since sparks may
ignite the gas.
OUTDOOR AM ANTENNAS
If it is not possible to obtain adequate AM reception even by
changing the orientation of the AM loop antenna, a separate
indoor antenna, or an outdoor antenna should be installed.
INDOOR AM ANTENNA
Use a vinyl insulated wire (5 — 6 m) and connect one end to
the AM antenna terminal and affix the other end to the wall or
ceiling, as high as possible.
OUTDOOR AM ANTENNA
If reception quality is not improved sufficiently even when an
indoor antenna is used, a vinyl insulated wire should be
installed outside and fixed in place.
NOTE:
Do not detach the AM loop antenna when using an indoor or an out-
door AM antenna.

TROUBLESHOOTING
Incorrect operations are often mistaken for trouble and malfunctions. If you think that there is something wrong with this compo-
nent, check the points below. Sometimes the trouble may lie in another component. Investigate the other components and elec-
