Dolby NR System
This cassettedeck providesa choice
betweenthe Dolby B-type and the Dotby
C-lype noise reductionsystems.The Dolby
B-type NR providesapproximately10 dB of

system,which achievesa S/N ratio
improvementof about 20 dB in the range
trom 2 kHz to 8 kHz, where noise is most
readilyaudible,
For playbackof a tape which was recorded
with the B-type NR, set the Dolby NR
switch to "B". For playbackof a tape
recordedwith Dolby C{ype NR, set the
switch to "C".
Precautions
BeforeOperation
(1) This deck incorporatesa muting circuit
which is active for about 4 seconds after
the power was switched on, until all
circuits have becomestable.
(2) lf the power is switched on while the
Timer switch is set to "Rec" or "Play",
recordingor playback will start
automatically.In order to prevent
accidentalerasureof a tape, be sure to
set the Timer switch to "Off" when the
timer function is not desired.
(3) lf during playback or recordingthe power'
to the deck was switched off by an
externaltimer or the like, it may
afterwardsnot be possibleto depress the
Eject button.Do not apply excessiveforce
in such a case. Set the Timer switch of
the deck to "Oft", and then switch the
power to the deck back on. The cassette
can now be removed.
(4) This cassettedeck incorporatesa special
circuit design€dto take up any tape slack
when a cassetteis inserted.Upon closing
the cassettecompartmentor switchingon
the power,the left spindle will rotate and
the tape counter indicationmay change
slightly.This behavioris normaland not a
fault with the deck.
(5)Voltage Selector
AC voltageis factory-setfor the country
in which you purchasedyour cassette
deck. The voltageselector permits
re-settingof mains voltagein case the
deck is to be used in a different country.
Note:
Safety regulationsin certain countries
prohibit inclusionof a voltageselector.
This feature,therefore,may be absent
trom your deck.

Record Level Setting
For goodrecordings,it is essentialto maintain
a high signal-to-noise
ratio.lf the recordlevel

I Bias Tune Control
This deck providesa Bias Tune control which
permitsfine adjustmentol the bias current
after the standardvalues have been set with
the Tape Selectorswitches.Reducingthe bias
current extendshigh-frequencyresponse,but
distortiontends to increase.Reversely,
increasingthe bias current reduces distortion
but curtails high-freguencyresponse.
When using tapes from the above list, the bias
tune controlshouldbe left in the center
click-stop position.When using other tapes,
adjustthe bias while comparingthe soundof
the inputsignaland the recordedsignal.This
comparisoncan best be done by recording FM
interstationnoiseor a similarsignalat about
- 30 dB to - 20 dB and switchingthe Monitor
switch back and forth between"Source" and
"Taoe".
(1) lf the recordedsignal sounds brighter than
the originalsource,turn the Bias Tune
This cassettedeck was calibratedat the

controlto the lelt (-).
(3) By repeatingsteps (1) and (2) and
monitoringthe results,adjust the Bias Tune
controlto minimizeany sound quality
differences.
Maintenance
Be careful that the cotton tip does not get
caught betweenthe roller and the capstan.
(3) Press the Pausebutton to releasethe
pressurerollers from the capstans.Now
clean the capstansand the surfaces of the
headsand tape guideswilh a cotton-tipped
stick. Be careful not to apply too much
force.Take special care not to damagethe
tape and preloadingguides and the tape-pad
lifter.
o After cleaning,make sure that no cotton
'
strands are lelt on any of the cleaned
pans.
. In case of severe contaminalion,
moistenthe cottontio with a small
amountof commercially
available
cleaningfluid designedespeciallyfor
this purpose.Alter cleaningwith a
cleaningfluid,wait untilany residuehas

Cleaning
It is very importantto regularlyclean the head
surfaces and transport section,etc.
Contaminationcaused by tiny particles
sheddedfrom the tape onto these parts can
becomethe cause of drop-outs and severely
degradehighJrequency responseand
wow-andJluttercharacteristics.Perform
cleaningabout once every 10 hours of use.
(1) Removethe cassette holder cover and push
the cassette holder back in.
Demagnetizing
Alter a longerperiodof use,there can be a
build-upof residualmagnetismin the heads
and capstans.Such residual magnetismcan
inducenoiseand partiallyerasethe high
