recorder to a CD player or a cassette recorder using either digital (optical) input or analog  
(line) input. To record, see Recording an MD right away!(page 10) to record using  
record using analog (line) input.

When you record in LP4 stereo mode,  
momentary noise may be produced on very  
rare occasions with certain sound sources.  
This is because of the special digital audio  
compression technology that enables a  
recording time 4 times longer than normal. If  
noise is produced, it is recommended that you  
record in normal stereo or LP2 stereo mode to  
obtain better sound quality.  
1) For better sound quality, record in normal  
stereo or LP2 stereo mode.

sounds from left and right will be mixed.

You can achieve high sound quality and rich  
tones when recording in normal stereo (or

Acoustic Coding).  
What is the newly developed DSP  
TYPE-R for ATRAC?  
TYPE-Ris a high-level Sony specification  
used in the Digital Signal Processor (DSP),  
which is heart of the MiniDisc sound. This  
technology gives the MiniDisc recorder twice  
the signal processing capability as previous  
MiniDisc Walkman models, producing a  
sound quality close to that of MiniDisc decks.

Additional information  
Preventing hearing damage  
Avoid using headphones/earphones at high  
volume. Hearing experts advise against  
continuous, loud and extended play. If you  
experience a ringing in your ears, reduce the  
volume or discontinue use.  
Precautions  
On safety  
Do not put any foreign objects in the DC IN 3V  
jack.  
Caring for others  
On power sources  
Keep the volume at a moderate level. This will  
allow you to hear outside sounds and to be  
considerate of the people around you.  
Use house current or LR6 (size AA) battery.  
For use in your house: Use the AC power  
adaptor. Do not use any other AC power  
adaptor than the ones designated for this  
recorder since it may cause the recorder to  
malfunction.  
On the MiniDisc cartridge  
When carrying or storing the MiniDisc, keep  
it in its case.  
Do not break open the shutter.  
Do not place the cartridge where it will be  
subject to light, extreme temperatures,  
moisture or dust.  
Attach the supplied MD label only in the  
space designated for it on the disc. Do not  
stick it on any other disc surface.  
Polarity of the  
plug  
The recorder is not disconnected from the AC  
power source (mains) as long as it is  
connected to the wall outlet, even if the  
recorder itself has been turned off.  
If you are not going to use this recorder for a  
long time, be sure to disconnect the power  
supply (AC power adaptor or dry battery). To  
remove the AC power adaptor from the wall  
outlet, grasp the adaptor plug itself; never pull  
the cord.  
On cleaning  
Clean the recorder casing with a soft cloth  
slightly moistened with water or a mild  
detergent solution. Do not use any type of  
abrasive pad, scouring powder or solvent such  
as alcohol or benzene as it may mar the finish  
of the casing.  
On heat build-up  
Heat may build up in the recorder if it is used  
for an extended period of time. In this case,  
leave the recorder turned off until it cools down.  
Wipe the disc cartridge with a dry cloth to  
remove dirt.  
Dust on the lens may prevent the unit from  
operating properly. Be sure to close the disc  
compartment lid after inserting or ejecting an  
MD.  
To obtain the best sound quality, use a dry  
cloth to wipe the plugs of the headphones/  
earphones. Dirty plugs may cause sound  
distortion or intermittent breaks in the sound.  
On installation  
Never use the recorder where it will be  
subjected to extremes of light, temperature,  
moisture or vibration.  
Never wrap the recorder in anything when it is  
being used with the AC power adaptor. Heat  
build-up in the recorder may cause  
malfunction or damage.  
Notes on battery  
Incorrect battery usage may lead to leakage of  
battery fluid or bursting battery. To prevent  
such accidents, observe the following  
precautions:  
On the headphones/earphones  
Road safety  
Do not use headphones/earphones while  
driving, cycling, or operating any motorized  
vehicle. It may create a traffic hazard and is  
illegal in many areas. It can also be potentially  
dangerous to play your recorder at high volume  
while walking, especially at pedestrian  
crossings. You should exercise extreme caution  
or discontinue use in potentially hazardous  
situations.  
Install the + and poles of the battery  
correctly.  
Do not try to recharge dry battery.  
When the recorder is not to be used for a long  
time, be sure to remove the battery.  
If a battery leak should develop, carefully and  
thoroughly wipe away battery fluid from the  
battery compartment before inserting new  
ones.

Note on mechanical noise  
The recorder gives off mechanical noise while  
operating, which is caused by the power-saving  
system of the recorder and it is not a problem.

This recorder uses the Serial Copy  
Management System, which allows only first-  
generation digital copies to be made from  
premastered software. You can only make  
copies from a home-recorded MD by using the  
analog connections.  
If you have any questions or problems  
concerning your recorder, please consult your  
nearest Sony dealer. (If a trouble occurred when  
the disc was in the recorder, we recommend that  
the disc be left in the recorder when you consult  
your Sony dealer so that the cause of trouble  
may be better understood.)

System limitations  
The recording system in your MiniDisc recorder is radically different from those used in  
cassette and DAT decks and is characterized by the limitations described below. Note,  
however, that these limitations are due to the inherent nature of the MD recording system  
itself and not to mechanical causes.  
Symptom  
Cause  
TrFULLappears  
even before the disc  
has reached the  
maximum recording  
time (60, 74, or 80  
minutes).  
When 254 tracks have been recorded on the disc, TrFULL”  
appears regardless of the total recorded time. More than 254  
tracks cannot be recorded on the disc. To continue recording,  
erase unnecessary tracks.  
TrFULLappears  
even before the disc

time.  
Repeated recording and erasing may cause fragmentation and  
scattering of data. Although those scattered data can be read,  
each fragment is counted as a track. In this case, the number of  
tracks may reach 254 and further recording is not possible. To  
continue recording, erase unnecessary tracks.  
Track marks cannot be When the data of a track is fragmented, the track mark of a

fragment under 12 seconds long (recorded in stereo), 24 seconds  
long (recorded in LP2 stereo mode or monaural mode), or 48  
seconds long (recorded in LP4 stereo mode) cannot be erased.  
You cannot combine tracks recorded in different recording  
modes, e.g., a track recorded in stereo and a track recorded in  
monaural; nor can you combine a track recorded with digital  
connection and a track recorded with analog connection.  
Tracks of under 12 seconds, 24 seconds, or 48 seconds in length  
are not counted and so erasing them may not lead to an increase  
in the recording time.

recorder will automatically insert a blank space amounting to 2  
seconds, 4 seconds, or 8 seconds before the next recording.  
(This is to prevent accidental erasing of a previous track  
whenever a new recording is started). Therefore, the actual  
recording time will decrease whenever a recording is stopped by

Explanations  
How the MiniDisc got so small  
The 2.5-inch MiniDisc, encased in a plastic  
cartridge that looks like a 3.5-inch diskette,  
uses a new digital audio compression  
technology called ATRAC (Adaptive  
TRansform Acoustic Coding). To store more  
sound in less space, ATRAC extracts and  
encodes only those frequency components  
actually audible to the human ear.  
Quick Random Access  
Like CDs, MDs offer instantaneous random  
access to the beginning of any music track.  
Premastered MDs are recorded with location  
addresses corresponding to each music  
selection.  
Recordable MDs are manufactured with a  
User TOC Areato contain the order of the  
music. The TOC (Table of Contents) system  
is similar to the directory management  
systemof floppy disks. In other words,  
starting and ending addresses for all music  
tracks recorded on the disc are stored in this  
area. This lets you randomly access the  
beginning of any track as soon as you enter  
the track number (AMS), as well as label the  
location with a track name as you would a  
file on a diskette.
