1 – Introduction  
Additional information is presented as necessary in sec-  
tions with “TIP,” NOTE” and “CAUTION” labels.  
Cleaning the cassette recorder head section  
If the cassette recorder head becomes dirty, the quality of  
playback and recording could be degraded and the sound  
could even be interrupted.  
Tips suggest ways that the unit can be used.  
Moreover, if the tape transport becomes dirty, the tape  
could become entangled, for example. Clean the cassette  
recorder’s head, pinch roller and capstan using a cotton  
swab moistened with a commercially available cleaning  
fluid after about every 10 hours of use.  
Notes provide additional explanation and describe spe-  
cial cases, for example.  
CAUTION  
Cautions are instructions that must be followed to avoid  
possible injury, equipment malfunction or damage to  
CDs or cassette tapes.  
CAUTION  
Do not play or record a tape until the cleaning fluid has  
dried.

About compact discs (CDs)  
In addition to commercially-available music CDs, this unit  
can play CD-R and CD-RW discs that have been recorded  
in audio CD (CD-DA) format, as well as CD-R and CD-RW  
discs that have MP3 audio and WAV audio files recorded on  
them. This unit can also play 8-cm CDs.  
Precautions for placement  
The guaranteed operating temperature of this unit is  
between 5º and 40º C.  
Install the unit in a level position.  
To improve dissipation of heat, do not place other items  
on top of this unit.  
Precautions for CD use  
Do not place this unit on top of a powered amplifier or  
other equipment that generates much heat.  
Always place compact discs in the tray with their labels  
facing upward.  
To remove a disc from its case, press down on the center  
of the disc holder and lift the disc out by its outer edge.  
Beware of condensation  
Do not touch the signal side (the unlabeled side).  
Fingerprints, oils and other substances can cause errors  
during playback.  
Condensation could occur if the unit is moved from a cold  
place to a warm place, used in a room that has just been  
heated or subject to other sudden temperature change. To  
prevent this, let the unit sit for one or two hours before  
turning the power on in such situations.  
If there are fingerprints or dust on the signal side, use  
a soft cloth to wipe it gently from the center outwards.  
Dirt on discs can lower the sound quality, so clean them  
and always store them in a clean state.  
Never use record cleaner, antistatic solutions, benzene,  
thinner or other chemical substances to clean a disc.  
Doing so could damage the surface and make the CD  
unplayable.  
Cleaning the unit  
To clean the unit, wipe it gently with a soft dry cloth. Do  
not use chemical cleaning cloths, benzene, paint thinner,  
alcohol or other chemical agents to clean the unit as they  
could damage the surface or cause fading.  
Do not apply labels or other materials to discs. Do not  
use discs that have had tape, stickers or other materi-  
als applied to their surface. Do not use discs that have

sticky residue from stickers, etc. Such discs could  
become stuck in the unit or cause it to malfunction.  
movement or that make unusual noises during fast-  
forwarding and rewinding should not be used.  
Never use commercially available CD stabilizers. Their  
use could make disc playback impossible or cause the  
unit to malfunction.  
Long-play tapes  
Tapes that are longer than 90 minutes are very thin and  
easily stretched, which can result in warbling or flutter.  
Moreover, these tapes can become entangled in the  
equipment, so their use should be avoided.  
Do not use cracked discs.  
Do not use specially shaped discs, including heart-  
shaped, business card-shaped or octagonal discs. Using  
such discs could damage the unit.  
Precautions for cassette use  
Do not open cassettes or pull out their tape.  
Do not touch the side of the tape that has the magnetic  
coating with bare hands.  
With the intention of protecting copyrights, several  
record companies sell discs with a “copy control CD”  
designation. Some of these discs do not comply with CD  
specifications and might not be playable in this unit.  
Do not leave them in places with lots of garbage or dust.  
Do not use or store them in hot or humid places.  
Avoid using or storing them in places with strong mag-  
netic fields. Doing so could cause noise or the erasure of  
recorded contents.  
About cassette tapes  
Dolby NR  
Usable types of tapes  
Dolby NR reduces tape hiss during recording. This unit has  
Dolby B Type noise reduction.  
Recordable tapes:Type I (normal)  
Type II (high position/chrome)  
Playable tapes: Type I (normal)  
Type II (high position/chrome)  
Dolby NR affects both recording and playback, so you  
should set NR ON or OFF, using the same setting during  
playback as used during recording.  
On cassettes that have been recorded with Dolby NR  
make a note that Dolby B NR is ON.  
Type IV (metal)  
Write-protection tabs for preventing unintentional  
recording  
Cassettes have write-protection tabs to prevent the  
unintentional erasure of recordings. There are tabs for  
cassette sides A (1) and B (2). Use the tip of a screwdriver  
or similar tool to remove these tabs to prevent future  
recording. Put adhesive tape over the hole to allow  
recording again.  
Tape slack  
Before using a cassette confirm that the tape is not slack.  
Slack tape could become entangled in the capstan or other  
parts. Use a pencil or the like to wind the tape until it is no  
longer slack.  
Automatic tape type detection holes  
Cassettes have automatic tape detection holes that allow this  
unit to automatically determine the type of tape inserted.  
Types of cassette tapes that are not recommended  
for use with this unit  
Use of the following types of cassette tapes might prevent  
normal operation or performance. Moreover, use of these  
types of tapes should be avoided because they could become  
entangled in the unit and result in unexpected malfunction.  
Irregular cassette tapes  
Cassettes that are deformed, have irregular tape

If you want to output the CD and tape signals to  
different devices (or different channels of a mixer,  
for example), set the COMMON OUT item to “TAPE.”  
By doing so, the CD signal will be output from the CD  
OUTPUT jacks, while the tape signal will be output  
from the TAPE COMMON OUTPUT jacks.  
Precautions for the use of batteries  
Misuse of batteries can cause them to leak or rupture, for  
example. Please read the battery caution indications and  
page 4 of this manual carefully.  
If you’re outputting the signal of this unit to one ex-  
ternal device, such as an amplifier, set the COMMON  
OUT item to AUTO” or “MIX.” By doing so, this unit  
outputs the signal of the CD and/or the tape depend-  
ing on their playback status.

5 – Playing Back CDs  
This chapter explains the playback functions of this unit’s  
CD player.  
Discs that can be played  
This unit’s CD player can play the following types of discs.  
• CD-DA (audio CD) format discs  
This unit can play commercially available audio CDs and  
CD-R and CD-RW discs that have been recorded in audio  
CD format. These discs are called “ audio CDs” in this  
manual.  
• CD-ROM (data CD) format discs  
This unit can play discs that contain MP3 and WAV files.  
These discs are called “data CDs” in this manual.  
MP3 files that can be played include files that have sam-  
pling frequencies of 32, 44.1 or 48 kHz, and bit rates of  
32 to 320 kbps or variable bit rate (VBR). WAV files that  
can be played include files that have sampling frequen-  
cies of 8 to 48 kHz and are 8-bit or 16-bit.  
Folder  
CAUTION  
MP3/WAV file  
MP3 files that use VBR compression  
Due to format limitations, positions in VBR files cannot  
be accurately detected. For this reason, when using the  
call function, the A–B repeat function or other functions  
that require points to be set in the middle of tracks, the  
points set and the actual playback starting points might  
be slightly different.  
An Example of Data CD Structure  
Loading a CD  
To load a CD, press the OPEN/CLOSE key on the main unit  
or the remote control to open the disc tray and place a disc  
on it with the label side up.  
Data CD folders and tracks  
This unit treats all the audio files (WAV and MP3) on data  
CDs as “tracks.” Some data CDs store files inside folders  
in the same way that ordinary computers do. In addition,  
multiple folders can be stored inside another folder creating  
a multilevel structure.  
Press the OPEN/CLOSE key again to close the disc tray.  
After a disc is loaded, this unit reads the disc information  
and shows on the display the total number of tracks and  
total playback time for an audio CD or the total number of  
tracks in the current folder or on the entire disc for a data  
CD.  
This unit assigns a folder number to each folder to manage  
them. Folder numbers are assigned sequentially starting  
with the first folder at the highest level followed by the  
folders (subfolders) inside it. Folders inside a higher-level  
folder are numbered in order before the next folder in the  
higher-level is numbered as shown in the illustration below.  
If the root folder of a data CD contains one or more audio  
files, it will be numbered as the first folder.  
Each audio file is also assigned a track number. Track  
numbers are assigned in order starting from those in the  
lowest numbered folder. During ordinary playback of data  
CDs, tracks are played back in the order of their assigned  
numbers just like the tracks on an audio CD. Folders that  
do not directly contain audio files are not given numbers.  
For example, in the illustration below the folder that  
contains folder 5 is not given a number.

(See “Recording” on page 39.)  
The tape automatically rewinds to the start of the A side,  
and the tape counter resets to “0000.” The CD pauses at  
the beginning of its first track. After the tape records about  
eight seconds of silence (to avoid the leader tape), dubbing  
starts with the CD beginning playback and the cassette  
recorder beginning recording at the same time. (The DUB  
indicator appears on the display.)  
Press the CD STOP key to stop the CD and the TAPE  
STOP key to take the unit out of record ready mode.

Using the TAPE EDIT function  
When the CD playback stops or the tape end is  
reached, the tape stops (the tape side end that it  
stops at depends on the reverse mode) and dubbing  
ends.  
Using the TAPE EDIT function, this unit can follow an  
automatically prepared program and dub a CD according to  
the tape length.  
With the TAPE EDIT function, starting with the first track,  
CD tracks that total less than the length of the tape side are  
recorded in order to the A side of the tape. Then, recording  
continues from the next track in order to the B side.  
When dubbing in two-side recording mode, if the  
last track being recorded to the first side of the tape  
is not recorded completely before the operation  
direction reverses, that track is recorded again from  
its beginning on the second side of the tape.

When CD playback is stopped, press the TAPE EDIT  
key on the remote control to enter TAPE EDIT  
mode. The main display appears as shown below.  
When dubbing in two-side recording mode, nothing  
is recorded for eight seconds after the operation  
direction is reversed. (CD playback pauses while the  
cassette recorder continues in record mode.)  
Press the TAPE or CD STOP key to stop dubbing at  
any time.  
Adjusting the record level when dubbing  
The recording level is automatically set when dubbing a  
CD to a tape by default, but the record level can be adjusted
