@® DOLBY NR switch
For recording and playback with Dolby NR* (Noise Reduction) pro-
cess, set this switch to ON. For recording and playback without
Dolby NR process, set it to OFF.
* Through the Dolby NR system, tape hiss is reduced and signal-to-noise ratio is improv-
ed.
During recording low-level high-frequency signals, which are either partially or totally con-
cealed by tape noise, are boosted ; thereby, allowing the recorded material to be heard
above the tape hiss level. When playing back this recording, the reproduction level is
fowered to the original input level. Simuitaneously, the noise tevel which was mixed with
the recorded material is also reduced in volume, eliminating much of the background
noise from these fow-level high-frequency passages.
“Dolby” and the double-D symbol are trade marks of Dolby Laboratories. Noise reduction
system manufactured under license from Dolby Laboratories.
@ INPUT SELECT switch
For recording through MIC jacks, set this switch to the MIC posi-
tion. For recording through LINE IN jacks, set it to the LINE posi-
tion.

; recording in your dissatisfied spot on a recorded tape.

RECORDING LEVEL ADJUSTMENT
A high recording level is recommended to reduce annoying tape
noise,
but
overloaded
and
distorted
tapes
could
result
if
the
level
is
too
high.
Recording
level
should
be
set
at
the
maximum
permissi-
ble for each type of tape. The higher the tape maximum output
level
is,
the
higher
the
recording
level
can
be
set,
which
provides
the full dynamic range of the tape and a better signal-to-noise ratio.
Note
the
general
points
on
adjusting
the
recording
level
as
follows.
Setting too high (distorted recording): The peak program meters
deflect continuously to full scale.

However, consideration has to be given to the fact that tape satur.
tion and distortion at higher frequencies occur at lower level
When recording programs containing strong, sharp pulses, such é
certain live programs, the level may be too high if adjusted in tr
way described, and distorted tapes could result. In such a cas
set the recording level lower than usual.
The peak program meters may indicate differently in recording ar
playback modes, but these small differences are not significant.

© Set the receiver controls for reproduction.
@ Set the timer for the desired time.
© Set the tape deck TIMER switch to ON.
@ Press and lock the forward button. The tape deck is now ready
for automatic start of playback at the timer-set time.
Notes
e@ Set the timer so that the tape deck is turned off after the locked
buttons are released by the automatic shut-off mechanism at the
tape end. For example, if a cassette giving 30 minutes of recor-
ding on one side is used on a program beginning at 8 : 00 a.m., the
locked buttons will be automatically released at 8:30 and there-
fore the timer should be set to turn off at about 8: 40 or 8: 45 to be
on the safe side. If the deck is turned off with buttons being lock-
ed, the pinch roller may be damaged.
@When not using a timer during recording or playback, do not set
the TIMER switch to ON. Otherwise, the tape will stop.

AUTO PLAY...
Auto-play is possible right after the tape is rewound to the tape
end.
When starting to rewind the tape, hold the rewind button pressed
and press the forward button. At end-of-tape only the rewind but-
ton is released and the tape is then played back automatically.

pressed. To record ona cassette whose tabs have been removed
simply cover the slot with plastic tape.
Do not stick any other material
To protect side A recording except on the portion marked.
Cassette care
@ Avoid touching the tape surface of a cassette, as any dirt or dus
may cause contamination of the heads.
@ Do not stick thick paper or tape into the cassette, as this may af
fect proper cassette alignment and prevent proper tape contac
with the head.
@ Protect cassettes from dust by storing them in their cases. Evel
minor dirt or dust could cause contamination of the heads resulting
in noise and sound drop-outs.
e@Keep cassettes away from magnetic equipment such a:
speakers, amplifiers, etc., as erasure or distortion on your recordec
tape could occur.
@Do not expose a cassette to direct sunlight, extremely cok
temperature or moisture.
@ Avoid fast-winding just before storing a cassette tape, as thi:
may cause stretching of the tape edge if the cassette is left unuse:
over a period of time.
Which cassette to use
This unit is preadjusted at the factory using the Sony FeC
Cassette, the Sony CD-@ Cassette and the Sony BHI
Cassette. All commercially available cassettes perform well witl
this unit. However, for optimum recording and playback results
we recommend Sony cassettes.
The letter A on the Sony cassette is embossed to help yo
distinguish that side of the cassette in a dimly lighted area.

| MAINTENANCE

@ Press the eject button to open the frame, and replace the lid.
@ After cleaning the heads and tape path, do not insert a cassette
until the cleaning fluid has dried completely.
Demagnetizing heads
Residual magnetism will gradually build up on the heads through
continuous use and cause erasure of high frequencies and hiss
build-up. The heads and metallic parts of the tape path should be
demagnetized after 20 to 30 hours of operation with the use of a
commercially available head demagnetizer.
Be sure the unit is turned off while demagnetizing the heads and
tape path.
Cleaning the cabinet
Clean the cabinet, panel and controls with a soft cloth lightly
moistened with mild detergent solution. Do not use any type of
abrasive pad, scouring powder or solvent such as alcohol or ben-
zine.
Inside check
Consult your nearest Sony service facility to maintain optimum per-
formance.
