INFORMATION
This equipment generates and uses radio frequency energy
and if not installed and used properly, that is, in strict
accordance with the manufacturer's instructions, may cause
interference to radio and television reception. It has been
type tested and found to comply with the limits for a Class B
computing device in accordance with the specifications in
Subpart J of Part 15 of FCC Rules, which are designed to
provide reasonable protection against such interference in a
residential installation. However, there is no guarantee that
interference will not occur in a particular installation. If this
equipment does cause interference to radio or television
reception, which can be determined by turning the
equipment off and on, the user is encouraged to try to
correct the interference by one or more of the following
measures:
Reorient the receiving antenna
Relocate the equipment with respect to the receiver
Mave the equipment away from the receiver
Plug the equipment into a different outlet so that
equipment and receiver are on different branch circuits.
If necessary, the user should consult the dealer or an
experienced radio/television technician for additional
suggestions. The user may find the following booklet
prepared by the Federal Communications Commission
helpful:
“How to Identify and Resolve Radio-TV Interference
Problems”.

Precautions
Installation
On safety
+ Operate the unit only on 120 V AC, 60Hz.
+ Before operating the unit, be sure that the operating
voltage of your unit is identical with that of your local power
supply
* Should any solid object or liquid fall into the cabinet,
unplug the unit and have it checked by qualified personnel
before operating it any further.
« Unplug the unit from the wall outlet if it will not be used for
a long time. To disconnect the cord, pull it out by grasping
the plug. Never pull the cord itself.
On operation
* When the unit is not used, turn the power off to conserve
energy and to extend the useful life of your unit.
» Because of a safety mechanism, the function buttons will
not operate if the cassette holder is not completely closed,
if there is no cassette in the cassette holder, or if a
cassette has been incorrectly inserted into the cassette
holder.
On head cleaning
The head and tape path should be cleaned after every ten
hours of operation. Dirty heads and a dirty tape path may
cause;
— loss of high-frequency response
— loss of sound volume
— sound drop-out
If you have any questions or problems concerning your unit,
please contact your nearest Sony dealer.
For detailed safety precautions, see the leaflet
“IMPORTANT SAFEGUARDS".
Notes on Installation
* Place the unit with the front panel facing you in a location
with adequate air circulation to prevent overheating of the
unit.
* Do not place the unit:
— near heat sources such as radiators or air ducts.
— in places subject to direct sunlight, excessive dust,
mechanical vibration or shock.
— in an inclined position.
— on a rug or other soft surfaces that would block the
ventilation holes on the bottom of the unit.
Do not throw away the carton and the packing material
They will come in handy when transporting the unit or shipping it for
servicing.
Connections
Notes on Connections
* Turn off the power to all equipment to be connected before
making any connection.
* Note that the red plug of the supplied connecting cord is
for right-channel (R) connection and the white plug for left-
channel (L) connection.
* The connecting cords should be fully inserted into the
jacks. A loose connection may cause hum pickup.

Tips on recording level adjustment
* If the recording level setting is too high, the recording will
be distorted; if it is too low, the tape will produce a hissing
sound. Therefore, the recording level should be set as high
as possible without causing distortion.
* If the program source to be recorded has many high
frequency signals, set the level to a relatively low position.
What is the Dolby HX PRO system?
The Dolby HX PRO system provides linearity in high-range
frequency response during recording. Tapes recorded with
this system retain the same high quality even when played
back on other tape decks.

Bias current — High
Established bias current
As shown above, characteristics such as output level and
distortion differ widely according to the bias (high-
frequency) current. In conventional systems, the bias
current is susceptible to variations in certain recording
signals (see diagram below) which may cause fluctuations
in frequency response, distortion, or other unwanted
characteristics,
High
| Fluctuation
Output
Frequency —— High
With the Dolby HX PRO system, the effective bias amount
added to the bias current is controlled in millisecond units to
greatly reduce distortion, improving linearity in high-range
response and ensuring high-intensity recording with minimal
distortion and noise.

Cassette Care
* Avoid touching the tape surface of a cassette to prevent
contamination of the heads by dirt, dust, or oil on the skin.
» Keep cassettes away from equipment with magnets, such
as speakers and amplifiers, as erasure or distortion of the
recorded tape could occur.
» Do not expose cassettes to direct sunlight, extremely cold
temperatures, or moisture.
Note on cassettes longer than 90 minutes
The use of cassettes longer than 90 minutes is not
recommended except for long continuous playback.

If the NORMAL or HIGH SPEED indicator blinks three times
Either ane or both tabs of the cassette inserted into deck B have

slot(s) with tape (see page 13).
Is it necessary to adjust the recording level and select the
Dolby NR system?
It is unnecessary since the tape in deck B is automatically recorded
with the same recording level and Dolby noise reduction system as
the origina! in deck A.
The Dolby system must, however, be set to match the tape in deck
A when the sound is monitored during normal-speed dubbing .
Using the Blank Skip function during tape dubbing
Pressing the BLANK SKIP button will activate the Blank Skip
function and turn on the BLANK SKIP indicator. When a blank of ten
seconds or more is encountered, dubbing will stop while the unit
fast winds to the next recorded portion, When one is found, dubbing
resumes.
Notes on tape dubbing
* Do not change the dubbing speed setting during tape dubbing.
« If the sound is affected by the proximity of a television set during
high-speed dubbing, turn the television set off or move it away
from the deck.

Maintenance
Cleaning the Heads and Tape Path
Clean all surfaces over which the tape travels after every
ten hours of operation to guard against:
— low-quality sound
— a decrease in sound level
— excessive wow, flutter or drop-out
— incomplete erasure
— impairment of recording function
To obtain high-quality recorded sound, cleaning before
every recording is recommended.
1 Press the 4 button to open the cassette holder. Grasp
the front holder on both sides and gently lift to remove it.
2 With the unit turned off, wipe the heads, the pinch rollers
and the capstans with a cotton swab slightly moistened
with alcohol or a commercially available cleaning fluid for
tape decks.

Demagnetizing the Heads
After 20 to 30 hours of use, or when you notice hiss and/or
loss of high trequencies, the residual magnetism built up on
the heads shouid be removed.
1 Turn off the power.
2 Demagnetize the heads with any commercially available
demagnetizer.
Refer to the instruction manual of the demagnetizer for
detailed instructions.
Cleaning the Cabinet
Clean the cabinet, panel and controls with a soft cloth
slightly moistened with a mild detergent solution.
Do not use any type of abrasive pad, scouring powder or
solvents such as alcohol or benzine.
