About the TOC
After any recording or editing function, "TOC" (Table Of
Contents) is displayed. To finalise the recording or editing
function, turn the power off. During this process "TOC"
will flash and "TOC EDIT!" will be displayed. During any
recording or editing function, the MiniDisc unit lid is
locked, and the MiniDisc cannot be removed until the
process is finalised.
Warning:
If the power is removed (Battery/AC adaptor) whilst
"TOC" is displayed, the MiniDisc unit lid will remain
locked until the battery/main power is restored and the
unit is turned on. Your new recordings or edited changes
will be lost and your MiniDisc may become unusable.
Caution:
Whilst "TOC" or "TOC EDIT!" is displayed, follow the
instructions below.
Otherwise, tracks may not be recorded properly.
 To prevent recorded MiniDiscs from
being erased accidentally
Slide the accidental erase prevention tab, located on the
side of the MiniDisc, in the direction indicated by the
arrow.
The MiniDisc will then be protected against accidental
erasure.
To add a recording to such a MiniDisc, slide the acciden-
tal erase prevention tab back to its original position.
 Helpful tip when attaching a label

to note the following. If the label is not attached properly,
the MiniDisc may jam inside the unit and you may not be
able to remove it.
- Do not jerk or bump the unit.
- Do not unplug the AC adaptor.
- Do not remove the battery.
- Do not subject the unit to shock.

If the label peels off or partially lifts
