0 Some of the troubles which seem to result from a malfunction of the
set-including the complete absence of sound from your speaker sys-
tems-are caused by wrong operation and the negligence of simple
maintenance, and can bequickly corrected by making a simple invesiga-
tion and providing simple cures. If, after making all the preparations
and operating the set as required, no sound is heard from your speaker
systems, go over the following check list once to make sure you havent

made any simple mistake.

CONNECTIONS

1. Have you connected the power cord to a wall AC
outlet?

2. Are the connecting cables for the turntable and tape
deck not loose?

3. Are the speaker cables not loose from the sets or
the speaker systems?

4. Are the left-right and plus-minus connections of
speaker systems; the input cables wrong?

OPERATING PROCEDURE

1. Have you turned on the POWER switch?

2. Is the SPEAKERS switch set the correct position?

3. Are the TAPE MONITOR switches not push to ON
position; though you dont want to reproduce a tape?
4. Is the SELECTOR switch set to the correct position?

HINTS FOR QUICK CHECKING

1. If absolutely no sound is heard from the speaker sys-
tems, check the program source components tape deck
turntable, etc.), set and speaker systems in that order
and see if they are connected and operated correctly.
The most common causes are, believe it or not, the
power cord unplugged from the wall AC outlet and the
connecting cables unplugged from the jacks.

2. If the set receives a broadcast normally, it is not
faulty. Check other components and their connections.
3. If hum noise is of a constant level,it may be stopped
simply by connecting the grounding lead of the program
source component(s) to the sets GND terminal.

ABOUT THE FM DE-EMPHASIS SWITCH

Use this switch insidethe set only if you move to an
area where the FM de-emphasis characteristic is differ-
ent. It is adjusted to the correct de-emphasis charac-
teristic of your area in our factory prior to shipment, so
there is normally no need to touch it. The correct
de-emphasis is 50 ,usec. for Japan and Europe, and
75 ysec. for the USA. and southeast Asia.

HOWLING AND HUM

Take care never to place a turntable on or too near
a speaker system, or the vibration produced by the
speaker system is transmitted and causes an oscillating
phenomenon called howling. it is best to keep these
components completely separated, but if this is impos-
sible, place a thick cushion between them. Humming,
in contrast, is a phenomenon caused by incomplete or
incorrect turntable-amplifier connections. Should this
occur, check to see if all connections are completely
made and if the connecting cables are sufficiently thick.
Hum noise may sometimes be eliminated by connect-
ing the grounding lead of the turntable to the GND ter-
minal on the rear panel.

ABOUT THE QUICK-ACTING FUSES

When a Selector Indicator is glowing, if no sound
comes out of one or more of the four speaker systems,
examine their connections and operation once. If
nothing is wrong with them, it is possible that the
quick-acting fuse or fuses protecting the power transis-
tor have blown.

If this should happen, disconnect the power cord
from the wall AC outlet immediately and check the four
quick-acting fuses inside the set. To reach them, re-
move the wood case from the set. If you find any of
them blown, discover and eliminate the cause of the
blowout, and replace it with a 3.5-ampere quick-acting
fuse supplied. Probable causes of the blowout include
excessively large input signals and a short-circuit at the
speaker terminals.

SHOULD THE POWER FUSE BLOW

If no Function Indicator sould glow and the set
simply remains dead even after you have turned on its
POWER Switch, it is possible that its power fuse has
blown.

If this happens, disconnect the power cord from the
wall AC outlet at once and examine the power fuse on
the rear panel. lfyou find it blown, replace it with a
new glass-tubed fuse of the rated capacity (6-ampere
for 100 to 117 volts, 3.5-ampere for 220 to 240 volts).

Never use a fuse of a different capacity or a piece of
wire, even as a stop-gap measure, or serious danger
could result.

ABOUT THE VOLTAGE ADJUSTMENT

Your set is adjusted to operate at the correct power
supply voltage of your area prior to shipment from our
factory.

If you move after purchasing it or send it as a gift to a
friend living in an area where the voltage is different, it
may be necessary to adjust its Voltage Selector.

To adjust it, remove the two screws securing the
name plate on the rear panel, then set the arrow mark
on the Voltage Selector Plug to the correct voltage
indication (100, 117, 220 or 240 volts). It may be neces-
sary to replace the power fuse as well whenever the
voltage has changed. For operation at 100 to 117 volts,
use a 6-ampere fuse. For operation at 220 to 240 volts,
use a 3.5-ampere one.
