INFORMATION
This equipment has been tested and
found to comply with the limits for a
Class B digital device, pursuant to Part
15 of the FCC Rules. These limits are
designed to provide reasonable
protection against harmful interference
in a residential installation. This
equipment generates, uses, and can
radiate radio frequency energy and, if
not installed and used in accordance
with the instructions, may cause
harmful interference to radio
communications. However, there is no
guarantee that interference will not
occur in a particular installation. If this
equipment does cause harmful
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 or relocate the receiving
antenna.
– Increase the separation between the
equipment and receiver.
– Connect the equipment into an outlet
on a circuit different from that to
which the receiver is connected.
– Consult the dealer or an experienced
radio/TV technician for help.
CAUTION
You are cautioned that any changes or
modifications not expressly approved in
this manual could void your authority
to operate this equipment.

—The recording level cannot be adjusted properly due
to excessive noise in the program source.
—The program source level is too low and the recording
level does not increase.
During a quiet passage in a program source such as
classical music, the recording level may not increase
for some time. If a high sound level is expected later
on in the track, play that portion first so that the right
adjustment can be obtained.

z To record with the optimum recording level
• To prevent changes in the recording level after
recording starts, press REC r while playing the
highest sound level portion of the program source to
be recorded. The result is a more natural-sounding
recording.
• If you play the entire program source after the AUTO
indicator has stopped flashing and is lit continuously,
the deck will set the recording level for the portion of
the program source with the highest signal level.
z Recording level setting remains even after the
recording has ended
After you have finished recording with the Auto Rec
Level function, the AUTO indicator remains on and the
recording level setting remains the same. To cancel the
setting, do one of the following:
• Press ARL to turn off the AUTO indicator
• Turn REC LEVEL
• Turn the deck off.
z What is the Auto Rec Level function?
The Auto Rec Level function automatically sets the
recording level according to the peak signal level of the
program source. While the AUTO indicator is flashing,
the deck sets the recording level as high as possible
without causing distortion. If the signal level rises
excessively after the start of recording, the deck
gradually decreases the recording level.

Tracks on a CD differ in length. Classical music CDs
and others often have tracks that exceed the recording

z When recording from the middle of the tape
A tape that is inserted and has not been played or

Precautions
On safety
• Do not disassemble the cabinet — this may result in an
electrical shock. Refer servicing to qualified personnel
only.
• Should any solid object or liquid fall into the cabinet,
unplug the tape deck and have it checked by qualified
personnel before operating it any further.
On power sources
• Before operating the tape deck, check that the operating
voltage of the tape deck is identical with your local power
supply. The operating voltage is indicated on the
nameplate at the rear of the tape deck.
• The unit is not disconnected from the AC power source
(mains) as long as it is connected to the wall outlet, even if
the unit itself has been turned off.
• If you are not going to use the tape deck for a long time,
be sure to disconnect the tape deck from the wall outlet.
To disconnect the AC power cord, grasp the plug itself;
never pull the cord.
• AC power cord must be changed only at the qualified
service shop.
On operation
• 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.
• Be sure to stop the tape before turning off the tape deck.
Otherwise, the tape may be damaged.
Notes on Cassette Tapes
To protect a recording on side A or B
Break out the respective tab.
Side A
Tab for side B
To record on a tape with a missing record-protect tab
Cover the respective tab hole with adhesive tape.
When you are using a type II or type IV tape, be careful not
to cover the detector slots that the deck uses to determine
the tape type.
Type II
Tab for side A
Type IV
On placement
• Place the tape deck in a location with adequate ventilation
to prevent heat build-up in the tape deck.
• Do not place the tape deck:
— on a soft surface such as a rug that might block the
ventilation holes on the bottom.
— in a location near heat sources.
— in a place subject to direct sunlight.
— in an inclined position.
— in a place subject to excessive dust or mechanical shock.
On cleaning the tape deck
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 solvent
such as alcohol or benzine.
If you have any questions or problems concerning your
tape deck, please consult your nearest Sony dealer.
Detector slots
Detector slots
On tapes longer than 90 minutes
We do not recommend the use of tapes longer than
90 minutes except for a long continuous recording or
playback. They are very thin and tend to stretch easily.
On handling cassettes
• To prevent the heads and tape path from getting dirty,
avoid touching the tape surface of a cassette.
• Place cassettes away from equipment with magnets, such
as speakers and amplifiers, which may cause tape
distortion or erase the recordings.
• Do not expose cassettes to direct sunlight, extremely cold
temperature, or moisture.

Cleaning the heads and tape path
Clean the heads and tape path of the tape deck after
every 10 hours of operation to guard against:
• low-quality sound
• a decrease in sound level
• excessive wow or flutter
• sound dropout
• incomplete erasure
• impairment of recording function
To ensure better recording, we recommend that you
clean the heads and tape path before every recording.
1 Press § to open the cassette holder. Grasp the
front cover on both sides and gently lift to remove
it.

Troubleshooting
If you’ve experienced any of the following difficulties
while using the tape deck, use this troubleshooting
guide to help you remedy the problem. Should the
problem persist, consult your nearest Sony dealer.
The function buttons do not work.
/ The tape deck has been just turned on and does
not operate for about 3 seconds. Wait until P
stops flashing.
/ Check that the cassette is inserted correctly and
the cassette holder is closed completely.
The tape deck does not play or record.
/ There is no cassette in the cassette holder.
/ The tape has come to the end.
/ The tape is slack. Take up the tape slack.
/ The record-protect tab has been removed from
the cassette (see page 13).
/ Make sure the amplifier setting is correct.
/ Check that the tape deck connections are
secure.
