Sony TCM-450DV は、カセットテープに録音・再生ができるカセットレコーダーです。単三電池2本で駆動し、内蔵のモノラルマイクロフォンで録音できます。また、別売りの外部マイクを接続して録音することも可能です。録音レベルは固定ですが、再生速度は3段階に調整できます。VOR（音声検知録音）機能を搭載しており、音声を検知したときに自動的に録音を開始し、無音になると自動的に録音を一時停止します。これにより、テープや電池の節約になります。テープカウンターを搭載しており、テープの位置を確認できます。イヤホン端子を搭載しており、イヤホンを接続して録音・再生した音声を聴くことができます。
本体背面には録音防止用シールが付いており、これを剥がすことで誤ってテープを上書きすることを防げます。また、マイク端子とイヤホン端子には触点があり、視覚障がいのある方でも操作

1 Open the battery
compartment lid.
2 Insert two R03 (size AAA)
batteries (not supplied) with
correct polarity and close the
lid.
To take out the batteries
(see Fig.

When to replace the
batteries
Replace the batteries with new ones
of the same kind when the REC/
BATT lamp dims and the E lamp
flashes.
The REC/BATT and E lamps
change as illustrated. (see Fig.
A
-
(d))
Notes
• The unit will play back normally for
a while, even after the E lamp
flashes. However, replace the
batteries as soon as you can.
Otherwise, the built-in speaker may
emit a loud noise and recordings
may not be made correctly.
•In the following cases you do not
need to replace the batteries:
– if the E lamp flashes with the
playback sound when you turn up
the volume.
– if the E lamp lights momentarily
when the tape starts running or at
the end of the tape.
– if the E lamp flashes during FF/
REW or CUE/REVIEW.

recommend that you use alkaline
batteries.
BOperating the Unit
Recording
(see Fig.
B
-(a), (b))
You can record right away with the
built-in microphone.
Make sure that nothing is connected
to the MIC jack.
1 Press the reset button of the
TAPE COUNTER.
2 Insert a normal (TYPE I) tape
with the side start recording
facing the lid.
3 Set REC TIME/PLAY MODE
to the desired mode.
NORMAL (4.8cm/s): for
optimum sound.
Recommended for normal
recordings. There is a tactile
dot on this side.
DOUBLE (2.4cm/s): for
double recording time (for
example, 120 minutes using
both sides of a 60-minute
cassette). Suitable for
recording conferences,
dictations, etc. Not
recommended for recording
music.
4 Set VOR to OFF.
If you set VOR to ON, the
unit automatically starts
recording the sound and
pauses when there is no
sound (you can save tapes
and batteries).
When the sound is not loud
enough, set it to OFF, or the
unit may not start recording.
5 Press z REC.
N PLAY is pressed
simultaneously and
recording starts. While the
tape runs, the REC/BATT
lamp lights and flashes
depending on the strength of
the sound.
Recording level is fixed.
At the end of the tape, recording
stops and the unit turns off
automatically (Automatic shut-off
mechanism).

Release the button at
the point to start
playback.
Take out Press x STOP and open
a cassette the cassette
compartment lid by
hand.
* PAUSE . will also be
automatically released when
x STOP is pressed (stop-pause-
release function).
Notes
• Do not use a High-position (TYPE II)
or metal (TYPE IV) tape. If you do
so, the sound may be distorted when
you play back the tape, or the
previous recording may not be
erased completely.
• The SPEED CONTROL switch (see
reverse side) works in the playback
mode only. Recording will be made
independent of this control.
Notes on VOR (Voice Operated
Recording)
• The VOR system is affected by the
environmental recording conditions.
When you use the system in a noisy
place, the unit will stay in the
recording mode. If the sound is too
soft, on the contrary, the unit will
not start recording.
If you cannot get the results you
want, set it to OFF.
• The VOR system may not record the
beginning of the sound you want to
record because it starts recording
only after it catches the sound. For
an important recording, set it to
OFF.
To monitor the sound
Connect an earphone (not supplied)
firmly to the EAR jack. The monitor
volume cannot be adjusted by VOL.
To prevent a tape from
being accidentally recorded
over (see Fig. B-(c))
Break off and remove the cassette
tabs. To reuse the cassette for
recording, cover the tab hole with
adhesive tape.

Recording from
Various Sound
Sources
Notes
• When you are going to record
something that you may not have an
opportunity to record again, test the
unit first before you actually start
recording.
• When recording with an external
microphone, the VOR system may
not work properly because of the
difference in sensitivity.
Recording with an
External Microphone (see
Fig. C)
Connect a microphone firmly to the
MIC jack.
Use a microphone of low
impedance (less than 3 kΩ). When
using a plug-in-power system
microphone, the power to the
microphone is supplied from this
unit.
Recording from Another
Equipment
Connect another equipment firmly
to the MIC jack using the
connecting cord (not supplied).
Set this unit to the recording mode
and another equipment to the
playback mode.
Playing a Tape (see
Fig. D)
1 Insert a normal (TYPE I) tape
with the side to start playing
facing the lid
2 Set REC TIME/PLAY MODE
to the same position as that
used for recording.
To playback commercially
available music tape, etc.,
select NORMAL.
3 Press N PLAY and then
adjust the volume.
There is a tactile dot beside VOL
on to show the direction to turn
up the volume.
4 Adjust the tape playback
speed.
Turn SPEED CONTROL to:
SLOW (slow) to play back at
a slower speed.
Center position to play back
at normal speed.
FAST (fast) to play back at a
faster speed.
At the end of the tape, playback
stops and the unit turns off
automatically (Automatic shut-off
mechanism). After the tape has
been wound or rewound, be sure to
press x STOP.
If you plug in headphones (not
supplied) to the EAR jack, you will
get monaural output from both left
and right channels.

B Additional
Information
Precautions
On power
• Operate the unit only on 3 V DC. For
battery operation, use two R03 (size
AAA) batteries.
On the unit
• Do not leave the unit in a location
near heat sources, or in a place
subject to direct sunlight, excessive
dust or mechanical shock.
• Should any solid object or liquid fall
into the unit, remove the batteries
and have the unit checked by
qualified personnel before operating
it any further.
• Keep personal credit cards using
magnetic coding or spring-wound
watches, etc. away from the unit to
prevent possible damage from the
magnet used in the speaker.
• When you do not use the unit for
long, remove the batteries to avoid
damage caused by battery leakage
and subsequent corrosion.
•If the unit has not been used for
long, set it in the playback mode and
warm it up for a few minutes before
inserting a cassette.
On tapes longer than 90
minutes
We do not recommend the use of tape
longer than 90 minutes except for a
long continuous recording or
playback. They are very thin and tend
to be stretched easily. This may cause
malfunction of the unit or sound
deterioration.
If you have any questions or problems
concerning your unit, please consult
your nearest Sony dealer.
Troubleshooting
Should any problem persist after
you have made these checks,
consult your nearest Sony dealer.
You cannot insert a cassettte or
close the cassette compartment
lid.
• The cassette is being inserted in the
wrong way.
• N PLAY has been already pressed.
The unit does not operate.
• The batteries have been inserted
with incorrect polarity.
• The batteries are weak. Replace
both batteries with new ones.
• PAUSE . is slid in the direction
of the arrow.
Recording cannot be made.
• There is no cassette in the cassette
compartment.
• The tab on the tape has been
removed. To reuse the tape for
recording, cover the tab hole with
adhesive tape.
• The batteries are weak. Replace
both batteries with new ones.
Recording is interrupted.
• The VOR switch is set to ON. When
you do not use VOR, set it to OFF.
Recording cannot be erased
completely.
•The erase head is contaminated. See
“Maintenance.”
• You are using a High-position
(TYPE II) or metal (TYPE IV) tape.
Playback cannot be made.
• The tape has reached the end.
Rewind the tape.
No sound comes from the
speaker.
• The earphone is plugged in.
Unplug it.
• The volume is turned down
completely.
The sound drops out or comes
with excessive noise.
• The volume is turned down
completely.
• The batteries are weak. Replace
both batteries with new ones.
• The heads are contaminated. See
“Maintenance.”
• Direct placement of the cassette
tape on the speaker resulted in
magnetization and deteriorated
tonal quality.
• You are using a High-position
(TYPE II) or metal (TYPE IV) tape.
• Use the unit away from radiowave-
emitting devices such as cellular
phones.
Tape speed is too fast or too
slow or the sound is distorted in
the playback mode.
• SPEED CONTROL is set at a point
other than the center.
• Improper setting of the REC TIME/
PLAY MODE switch. Set it to the
same speed as that used for
recording.
• The batteries are weak. Replace
both batteries with new ones.
There is a clicking noise during
tape operation.
• The unit is not in the stop mode.
Press x STOP.
Maintenance
To clean the tape heads and
path (see Fig. E)
Press N PLAY and wipe the heads,
pinch roller and the capstan with a
cotton swab, moistened with
alcohol every 10 hours of use.
