and fingerprints, grease, etc. can cause errors in the 
recording process.
•CD-R discs are more sensitive to the effects of heat 
and ultraviolet rays than ordinary CDs. It is impor-
tant that they are not stored in a location where 
direct sunlight will fall on them, and which is away 
from sources of heat such as radiators or heat-gen-
erating electrical devices.
•Always store CD-R discs in their “jewel cases” to 
avoid dirt and dust accumulating on their surfaces.
•Do not put labels or protective sheets on the discs 
and do not use any protective coating spray.
•When labeling CD-R discs, always use a soft oil-
based felt-tipped pen to write the information. 
Never use a ball-point or hard-tipped pen, as this 
may cause damage to the recorded side.
•Dirty discs may be cleaned using a soft dry cloth 
and/or a commercial CD cleaning fluid or ethyl 
alcohol. Do not use thinner, gasoline, benzene or 
LP cleaning fluid, as these will damage the disc.
•If you are in any doubt as to the care and handling 
of a CD-R disc, read the precautions supplied with 
the disc, or contact the disc manufacturer directly.
Never use a stabilizer, printable discs or a single adapter
Using commercially available CD stabilizers or 
printable recordable discs with this player will dam-
age the mechanism and cause it to malfunction.
You should not use an 8cm (“single”) adapter when 
using the CD-RW4U.
NOTE
Never use a disc that has had a stabilizer mounted to it. 
The residual adhesive may cause the disc to stick to the 
mechanism of the CD-RW4U. If it sticks to the mechanism, 
you will need a technician to get it out.
Recommended media
An up-to-date list of manufacturers who produce 
media suitable for use in the CD-RW4U can be 
obtained from your TASCAM dealer, or found on the 
TASCAM Web site at http://www.tascam.com.
Switching to audio mode
To switch to the audio CD recorder mode, follow the 
instructions below. For details of how to switch into 
USB mode, consult the details provided in the CD-
RW4U USB Operation Guide:
1Press the MENU key (E or 7) to show 
MODE > XXX.
2Use the MULTI DIAL (main unit) B or press 
the SKIP keys (remote control) I to change 
the display to MODE > AUDIO.
3Press the  MULTI DIAL (main unit) B or 
press the ENTER key (remote control unit) 
8. The unit enters audio mode in standby, 
showing AUDIO MODE (dimmed).
4Press the POWER key to enter audio mode.
NOTE
When the unit is in USB mode, and a USB cable is con-
nected to a powered computer, the unit enters active USB 
mode. When in USB mode and an active USB connection 
is disconnected, the unit enters USB standby mode. Mak-
ing or breaking the USB connection when the unit is in 
audio mode (active or standby) has no effect.
Although the USB cable can be connected and discon-
nected from the CD-RW4U in USB mode as described 
above, this is not recommended, as it may cause the com-
puter system to become unstable.
In USB mode, no front panel controls are operational, 
except the power/standby switch and the tray open/close 
key.
Also note that if an audio CD is being played by the unit in 
USB mode using the computer’s CD player software, the 
audio will not be output from the unit’s analog or digital 
ports.
Menu operations
The CD-RW4U uses menus to set various parame-
ters. These are made using the MENU key on the 
main unit or the remote control unit (E or 7).
Repeated presses of the MENU key cycle through the 
available menus as shown below “Default settings” 
on page 11.
