Refer to the following paragraph for the proper setting of this
switch
AC voitage selection
This unit operates on 110-120 or 220-240 volts AC. The AC
i voltage selector switch Type A or Type B on the rear panel is
; set to the voltage that prevails in the area to which the unit
is shipped. Before connecting the power cord to your AC out-
let, make sure that the setting position of this switch matches
your line voltage. If not, it must be set to your voltage in ac-
cordance with the following direction

IMPORTANT SAFEGUARDS
A\ Caution : Read this page carefully to ensure
safe operation.
Please read all of the safety and operating instructions
before operating this unit. For best results, follow all
warnings placed on the unit and adhere to the operat-
ing and use instructions. These safety and operating in-
structions should be retained for future reference
1. Power sources — The unit should be connected
to a power supply only of the type described in the
Operating instructions or as marked on the appliance
2.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, pay particular attention to cords at
plugs, convenience receptacles, and the point where
they exit from the unit
Never pull or stretch
the cord
3.Grounding or polarization — The precautions
should be taken so that the grounding or polariza-
tion means of this unit is not defeated
4. Ventilation — The unit should be situated so that
its location or position does not interfere with its
proper ventilation.
To maintain good ventilation, do not put records or
a table-cloth on the unit. Place the unit at least
10 cm away from the wails.
Do not use the unit on a bed, sofa, rug or similar
surface that may block the ventilation openings
5. Water and moisture — The unit should not be
used near water — for example, near a bathtub,
washbowl, kitchen sink, laundry tub, in a wet base-
ment, or near a swimming pool, etc.
6. Temperature — The unit may not function pro-
perly if used at extremely low, or freezing tempera-
tures. The ideal ambient temperature is above + 5°C
(41°F).
7.Heat — The unit should be situated away from
heat sources such as radiators, heat registers,
stoves, or other units (including amplifiers) that
produce heat
8. Electric shock — Care should be taken so that ob-
jects do not fall and liquid is not spilled into the en-
closure through openings. If a metal object, such as
a hair pin or a needle, comes into contact with the
inside of this unit, a dangerous electric shock may
result. For families with children, never permit chil-
dren to put anything, especially metal, inside this
unit
=
al
9. Enclosure removal — Never remove the en-
closure. If the internal parts are touched accidentally,
8 serious electric shock might occur.
10. Magnetic fields — Keep the unit away from
sources of magnetic fields such as TV sets, speaker
systems, radios, motorized toys or magnetized
objects.
11. Cleaning — Do not use volatile solvents such as
alcohol, paint thinner, gasoline, or benzine, etc. to
clean the cabinet. Use a clean dry cloth.

A\ Caution : Read this page carefully to ensure
safe operation.
12. Carts and stands — An appliance and cart com- ductors, location of antenna-discharge unit, connec-
bination should be moved with care. Quick stops, tion to grounding electrodes, and requirements for
excessive force, and uneven surfaces may cause the the grounding electrode. See Figure.

to qualified service personnel
17. Outdoor antenna grounding — If an outside an-
tenna is connected to the receiver, be sure the an-
tenna 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 The maximum capacities indicated for the AC out-
with respect to proper grounding of the mast and lets on the rear panel of this unit are as follows.

Notes: -
1. To prevent possible problems, always disconnact the power plug
or turn off the POWER switch of the receiver before connect-
ing or disconnecting the audio cables.
2. When connecting audio cables, always insert the pin plugs se-
curely into the connecting jacks.

@ Connecting the speakers
Connect speakers rated at 4 chm or more to the SPEAKERS
terminals
1. Connect the left speaker to the L speaker terminals on the
rear of the receiver and the right speaker to the R terminals
2. Connect each cable as shown in the illustration, taking care
that the wires do not make contact with other terminals
Notes: wo — -
1. Take care so as not to short the positive { +) and negative (—)
speaker cords.
2. Hf the left and right speakers, or positive and negative cables,
are connected the wrong way, the reproduced sound may be
unclear, with ambiguous location of the musical instruments etc.
To avoid this, pay attention to the left and right and positive
and negative indications when connecting the speakers.
@ Setting the speaker IMPEDANCE SELECTOR
When connecting one pair of speakers to the SPEAKERS A or
B terminals, set the IMPEDANCE SELECTOR according to the
speaker impedance.
When two pairs ot speakers are connected to both the A and
B terminals, match the speaker impedance selector to the
speakers with the lowest impedance
Notes: —
1. During speaker system connection and operation of the speak-
er IMPEDANCE SELECTOR, set the POWER switch to OFF.
2. Check that the connected lead wires of the speaker systems
do not contact with other jacks or t inais.

AC outlets _ — —
The AC outlets on the rear panel may be used to supply pow- ! WARNING
er to other components in the system, such as turntables, tape
decks, etc. Never connect equipment whose power consump-
tion exceeds the maximum value shown at each outlet. (in Eu-
rope, do not connect a main amplifier or similar components
to any of the AC outlets.)
SWITCHED outlets:
These outlets supply power only when the unit is turned on
The maximum total capacity is 200 watts
Particular attention must be given to making good elec-
trical contact at the receiver output and speaker ter-
minals.
; Poor or loose connections can cause sparking or burn-
‘ing at the terminals because of the very high power that |
| the receiver can deliver.

from the unit.
AM outdoor antenna
In steel buildings or at a great distance frorn the transmitter,
it may be necessary to install an outside long wire antenna
The end of this wire should be stripped of insulation and con-

from the top of the ''T’’ horizontally and hold them against
convenient wall surfaces. Try several locations for best results
with frequently listened to stations. Tape the antenna in place
where the best compromise is found between listening results
and appearance.
® To minimize auto-ignition noise, locate the antenna as
far from heavy traffic as possible
@ Keep the feeder or coaxial cable as short as possible.
Do not bundle or roll up excess cable.
