■ [Except for U.K. and Europe models]:  
■ The openings on the cabinet assure proper ventilation of the unit.  
If these openings are obstructed, the temperature inside the  
cabinet will rise rapidly and eventually damage the circuits.  
Therefore, avoid placing objects against these openings and do  
not install the unit where the flow of air through the ventilation  
openings could be impeded.  
This system is equipped with the newly developed Active Servo  
Processing Speaker System. It is not designed for use with  
conventional speakers. Therefore, do not attempt to connect  
other speakers than the provided speaker system.  
■ Choose the installation location of this unit carefully. Avoid placing  
it in direct sunlight or close to a source of heat. Also avoid  
locations subject to vibration and excessive dust, heat, cold or  
moisture. Keep it away from sources of hum such as transformers

CAUTION 1  
■ Never allow metallic items (e.g. screwdrivers, tools, etc.) to come  
near the cassette deck’s record/playback head assembly in this  
unit. Doing so may not only scratch or damage the head’s mirror-  
smooth finish, it may change the magnetic characteristics of the  
heads, causing a deterioration in reproduction performance  
quality.  
Use of controls or adjustments or performance of procedures  
other than those specified herein may result in hazardous  
radiation exposure.  
CAUTION 2  
■ Although the cassette deck’s record/playback heads used in this  
unit are high quality heads with outstanding reproduction  
characteristics, they can become dirty through the use of old  
tapes or from dust accumulation over time. This can have a  
serious effect on reproduction quality. Clean the heads regularly  
with one of the commonly available head cleaners or with  
cleaning solutions.

In the event of a power failure or when the AC supply  
lead is disconnected.  
The time display will go out, however, the clock will function  
for about 30 minutes without power supply. So you do not  
have to reset the time if the AC power supply is resumed  
within about 30 minutes.  
When the AC power supply is resumed after more than 30  
minutes pass without power supply, the time display will flash  
on and off to indicate that the time must be reset.  
Note  
If this system is left for several minutes without setting the  
time after the AC power lead of this system is connected to  
the AC outlet, there may be a case that the display is turned  
into a demonstration mode. (This mode is virtually  
unnecessary for using this system.)  
In this case, first turn the power on by pressing the POWER  
switch to cancel the mode, and then set the time.

COMPACT DISC PLAYER OPERATION  
Care of compact discs  
Compact discs are fairly resistant to damage, however  
mistracking can occur due to an accumulation of dirt on the  
disc surface.  
Follow the guidelines below for maximum enjoyment from  
your CD collection and player.  
Do not write on either side of the disc, particularly the non-  
label side. Signals are read from the non-label side. Do  
not mark this surface.  
•
Keep your discs away from direct sunlight, heat and  
excessive moisture.  
•
Always hold the CDs by the edges. Fingerprints, dirt or  
•
water on the CDs can cause noise or mistracking. If a CD  
is dirty or does not play properly, clean it with a soft, dry  
cloth, wiping straight out from the center, along the radius.

COMPACT DISC PLAYER OPERATION  
Direct operation  
Even when an input source other than CD player is selected,  
pressing the play/pause button, a disc select button, a track  
number input button or the RANDOM play button, or pressing  
the front edge of the disc table gently will start playback  
directly. In this case, if the tape deck is playing back a tape,  
it will be stopped automatically.  
* These ways of playback can also be used to close the disc  
table. If the table is closed in these ways, playback will  
begin automatically, however, the display will not show the  
total number of tracks and the total playing time of the disc  
to be played.  
PLAYXCHANGE  
During playback, you can open the disc table by pressing the  
PLAYXCHANGE button without interrupting disc playback.  
However, in this case, pressing the DISC SKIP button on the  
remote control transmitter has no effect.  
Precautions  
If TV or radio interference occurs during CD player  
operation, move the unit away from the TV or radio.  
•
Subjecting the unit to shock or vibration can cause  
mistracking.  
•
Playing some compact discs at high volume can cause  
mistracking. In this case, listen at lower volume.  
•
Do not push the disc table while it is moving.  
If the power fails while the table is open, wait until the  
power supply returns or gently push the table manually to  
close it.  
•
•
The temperature range for playing compact discs is  
recommended to be 5°C (41°F) – 35°C (95°F).

TUNING OPERATION  
Automatic preset tuning  
You can also make use of an automatic preset tuning  
function. By this function, this unit performs automatic tuning  
and stores stations with strong signals sequentially. Up to 40  
stations are stored automatically in the same way as in the  
manual preset tuning method on the previous page.

1 Press the TUNER input selector button.  
Receiver  
2 Press and hold the AUTO MEMORY button for about 2  
seconds.  
* The MEMORY and AUTO TUNING indicators will flash.  
This unit performs automatic tuning and received stations are  
programmed to A1, A2 ... A8 sequentially.  
After the automatic preset tuning is completed  
The display shows the frequencies of the first preset station  
(stored to A1).  
Check the contents and the number of preset stations by  
following the procedure of the section “To recall a preset  
station” on the previous page.  
2
To recall a preset station  
Simply follow the procedure of the section “To recall a preset  
station” on the previous page.  
Notes  
The automatic preset tuning search will be performed  
•
through all frequencies until 40 stations are stored. If the  
number of received stations is less than 40, the search will  
stop after searching through all frequencies.  
With this function, only stations with sufficient signal  
•
strength are stored automatically. If the station you want  
to program is weak in signal strength, tune to it in  
monaural manually and program it by following the  
procedure of the section “To store stations” on the  
previous page.  
You can replace a preset station by another FM or AM  
•
(MW or LW) station manually by simply following the  
procedure of the section “To store stations” on the  
previous page.  
Fundamental rules of internal automatic preset tuning  
operation  
Basically, FM stations are programmed onto area A, B and C,  
and AM stations are programmed onto area D and E (MW  
stations are onto D and LW stations are onto E) in that order  
automatically.  
* If, for example, the number of received FM stations is not  
enough to fill up three areas (A, B and C), AM (MW or LW)  
stations are programmed closely from the preceeding  
empty areas. In such a case, AM (MW) stations are  
programmed from area B or C (and LW stations are from  
area C or D.)  
Memory back-up  
The memory back-up circuit prevents the programmed data  
from being lost even if the AC supply lead is disconnected  
from the AC outlet or the power is cut due to temporary  
power failure. If, however, the power is cut for more than one  
week, the memory may be erased. If so, it can be re-  
programmed by simply following the Preset tuning steps.  
* Moreover, one area is programmed with stations of the  
same band only. If, for example, the last FM station is  
programmed to B4, B5–B8 will be programmed with no  
station, and AM (MW) stations are programmed from area  
C.

Dolby B and C Type Noise Reduction  
•
DOLBY B.C NR  
With cassette tapes, the most noticeable form of noise is high  
frequency hiss. To reduce this hiss noise, this unit has been  
equipped with a newly developed Dolby C noise reduction  
system in addition to its conventional Dolby B NR. Either type  
of noise reduction may be selected with the switch provided.  
Dolby B NR has a noise reduction effect of about 10 dB in  
the high frequency range. The corresponding figure with  
Dolby C NR is about 20 dB, but this is over the entire range  
where the human ear is most sensitive to noise (2 kHz to 8  
kHz). Also, Dolby C NR has the same noise reduction effect  
at both high and low signal levels. In addition, Dolby C NR  
improves the tape’s MOL (Maximum Output Level).  
Dolby noise reduction is a 2 part process that acts both on  
recording and playback; be sure that the noise reduction  
button is set to the same position on record and play.  
* Noise in the source material cannot be reduced with the  
Dolby NR system.

When the tape playback nears the end of the side, the  
indicator at the left end flashes rapidly. However, when using  
a tape with large hubs, the tape may stop before the indicator  
flashes. This is because the error between the displayed time  
and the actual elapsed time becomes large when using these  
tapes.  
Dolby B and C Type Noise Reduction  
Dolby HX PRO Dynamic Bias Servo System  
This unit incorporates the Dolby HX Pro system which  
automatically controls the effective bias to reduce distortion  
and noise, improving high frequency response during  
recording. Tapes recorded with this system retain the same  
high quality even when played back on any other tape deck.  
With cassette tapes, the most noticeable form of noise is high  
frequency hiss. To reduce this hiss noise, this unit has been  
equipped with a newly developed Dolby C noise reduction  
system in addition to its conventional Dolby B NR. Either type  
of noise reduction may be selected with the switch provided.  
Dolby B NR has a noise reduction effect of about 10 dB in

Active Servo

Signals of low amplitude  
The theory of the Active Servo Technology is based upon two  
major factors, the Helmholtz resonator and negative-  
impedance drive. Active Servo Processing speakers  
reproduce the bass frequencies through an “air woofer”,  
which is a small port or opening in the speaker’s cabinet.  
This opening is used instead of, and performs the functions  
of, a woofer in a conventionally designed speaker system.  
Thus, signals of low amplitude within the cabinet can,  
according to the Helmholtz resonance theory, be output from  
this opening as waves of great amplitude if the design is such  
that the size of the opening and the volume of the cabinet are  
in the correct proportion to satisfy a certain ratio.  
Thus it is this problem that is resolved through the  
employment of a design in which the amplifier functions to  
supply the signals. If the electrical resistance of the voice coil  
is reduced to zero, the movement of the speaker unit would  
become linear with respect to signal voltage, and, to  
accomplish this, a special negative-impedance output-drive  
amplifier for subtracting output impedance of the amplifier is  
used.  
By employing negative-impedance drive circuits, the amplifier  
is able to generate precise, low-amplitude low-frequency  
waves with superior damping characteristics, and these  
waves are then radiated from the cabinet opening as high-  
amplitude signals. The system can, therefore, by employing  
the negative-impedance output drive amplifier and a speaker  
cabinet with the Helmholtz resonator, reproduce an extremely  
wide range of frequencies with amazing sound quality and  
less distortion.  
In order to accomplish this, moreover, the amplitudes within  
the cabinet must be both precise and of sufficient power  
because these amplitudes must overcome the “load”  
presented by the air that exists within the cabinet.  
The features described above are combined to be the  
fundamental structure of the Active Servo Technology.
