z Additional Information
Precautions
On power
Operate the unit only on 1.5V DC. For AC operation, use the AC
power adaptor recommended for the unit. Do not use any other
type. For battery operation, use two size AAA (R03) batteries.
On the unit
• Use only the y (standard microcassettes) with this
unit. Non-standard cassettes cannot be used because their “L”
dimension (see illustration) is different.
• 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 or disconnect the AC power adaptor, and have the unit
checked by qualified personnel before operating it any further.
• 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 a long time, set it in the playback
mode and warm it up for a few minutes before inserting a tape.
Keep personal credit cards using magnetic coding or spring-wound
watches etc. away from the unit to prevent possible damage from the
magnet used for the speaker.
If you have any questions or problems concerning your unit, please
consult your nearest Sony dealer.
Using Various Functions
To select the side to be recorded
To record on both sides continuously
1 Insert a cassette with the side to start recording facing the
lid.
2 Start recording on the upper side (9 FWD appears in the
display window). If REV ( is displayed, press p STOP for
more than 2 seconds to display 9 FWD.
When recording reaches the end of the upper side, it will
automatically continue on the reverse side.
Notes
• Make sure the tabs on both sides are not removed.
• Even if only the tab on the reverse side is removed, recording
cannot be made.
To Record on one side only
1 Insert a cassette with the side to start recording facing away
from the lid (reverse side).
2 Start recording on the reverse side (REV ( appears in the
display window). If 9 FWD is displayed, press p STOP for
more than 2 seconds to display REV (.
When recording reaches the end of the reverse side, it will
automatically stop.
Note
Make sure the tab on the reverse side is not removed.
VOR (Voice Operated Recording)
The VOR system works only while recording. Press VOR to
display VOR L or VOR H first and then press r REC. The unit
automatically starts recording the sound and pauses when there
is no sound (you can save tapes and batteries).
VOR L: To record for dictation in a noisy place.
VOR H: To record at meetings or in a quiet place.
When you use this system in a noisy place the unit stays in the
recording mode. If the sound is too soft, on the contrary, the unit
will not start recording. Press VOR to display VOR L (low) or
VOR H (high) depending on the conditions. When you do not
use this function, press VOR during recording until VOR L or
VOR H disappears in the display window.
Notes
• The VOR system depends on the environment conditions. If you
cannot get the desired results, record without the VOR system.
• When using the VOR system, the unit starts recording only when a
sound is detected, therefore, the beginning of the word may not be
recorded. For an important recording, we recommend to recording
without the VOR system.
• The VOR L or VOR H indicator appears during playback too.
