12 TASCAM CD-RW4U
Power saving
The CD-RW4U provides a function that allows auto-
matic switching into standby mode after five minutes 
of inactivity (defined as no front panel or remote con-
trol unit control used, no commands received through 
the USB connection, and no disc playback or record-
ing).
To set this mode:
1Press the MENU key (E or 7) until the dis-
play shows: PWR SAVE>xxx, where 
xxx can be ON or OFF.
2Turn the MULTI DIAL (main unit) B or press 
the SKIP (remote control) I keys to change 
the value.
3Press the  MULTI DIAL (main unit) B or 
press the ENTER key (remote control unit) 8 
to return to the previous display.
When power saving is set on, every minute that the 
CD-RW4U is left on with no activity, the CD-RW4U 
shows a “countdown” message for a few seconds, 
Finalizing
Although audio data may be written on a CD-R or 
CD-RW disc, a standard CD player will not be able 
to read the data (i.e. play back the audio) until a final 
table of contents (TOC) has been written at the start 
of the disc.
The process of writing this table of contents is known 
as “finalizing”. Once this has been done, no further 
data can be written to the disc. See “Finalizing discs” 
on page 27 for details.
In the case of a CD-RW disc which has been final-
ized, the whole of the disc may be erased, or the disc 
may be “refreshed”, and the disc re-used. 
In addition, a CD-RW disc that has been finalized 
may be “unfinalized”, i.e. the TOC is removed. This 
allows further tracks to be recorded to the disc, pro-
vided that there is space on the disc.
