Using with the Alkaline Battery
Use one commercially available alkaline battery (LR6,
"AA" size). When using the alkaline battery, be sure to insert the
rechargeable battery also.
Caution:
While you are using the rechargeable battery and the
alkaline battery at the same time, do not remove either
of them. If you do, when the unit is in the play mode,
playback will stop. When in the recording mode, the
recorded contents will be erased, and the power may
be disconnected.
Do not replace the battery or the rechargeable battery
during operation.
Do not use a rechargeable battery (nickel-cad-
mium battery etc.) in the battery case.
If the unit is not used for a long period of time, remove
the battery. (Even if the power is turned off, the battery
will be drained slowly but continuously.)

MiniDisc System Limitations
The unit may have the following symptoms when recording or editing. The unit is not out of order.
SYMPTOM LIMITATIONS
"DISC FULL" or "TOC FULL" appears
even though the MiniDisc still has re-
cording time left.
More than 255 tracks (maximum) cannot be recorded regardless of
the recording time. If the MiniDisc is recorded or editedrepeatedly or
if it has scratches (recording skips scratched parts), you may not be
able to record the maximum tracks above.
The remaining recording time does not
increase even though you erased
tracks.
The unit does not count non-recorded portions that last 12 or fewer
seconds to display the remaining recording time. The time may not
increase even if you erase short tracks.
The total of the recorded time and the
remaining time does not match the max-
imum recordable time.
One cluster (approximately 2 seconds) is the minimum unit for re-
cording. For example, a 3-second track uses 2 clusters (approxi-
mately 4 seconds). Therefore, the actual recordable time may be
shorter than the displayed time.
(The number of seconds indicates that in the stereo recording mode
(SP). It varies depending on the recording mode.)
Combine function does not work. A MiniDisc on which recording and editing are repeated may not al-
low the combine function.
Sound skips in fast reverse/forward. If one track is divided and recorded in separate places on a repeat-
edly recorded or edited MiniDisc, sound may skip.
A track number is created in the middle
of a track. A track number may be created if there are scratches or dust on the
MiniDisc.
Troubleshooting
Many potential "problems" can beresolved by the owner without calling a service technician. If something seemsto be wrong
with this product, check the following before calling your authorized SHARP dealer or service center.
The unit does not turn on.
Is the AC adaptor disconnected?
Is the battery exhausted?
Is the unit in the hold mode?
Has condensation formed inside the unit?
Is the unit being influenced by mechanical shock or by
static electricity?
No sound is heard from the earphones.
Is the volume set too low?
Is the earphones plugged in?
Are youtrying to play a MiniDiscwith data onit instead
of a MiniDisc containing music?
When the operation buttons are pressed, the unit does
not respond.
Is the unit in the hold mode?
Is the battery exhausted?
Is the earphones plug inserted firmly?
Some sounds are skipped.
Is the battery exhausted?
Is the unit being subjected to excessive vibration?
The MiniDisc cannot be ejected.
Has the track number or character information been
written on the disc yet?
Is the unit in the recording or editing mode?
Recording and editing are impossible.
Is the MiniDisc protected against accidental erasure?
Is the unit connected properly to the other equipment?
Is the AC adaptor unplugged ordid a power failure oc-
cur when recording or editing?
Is the unit in the hold mode?
Is an optical signal being output from the stereo sys-
tem? Read the operation manual for the stereo sys-
tem.

and posture correction are perfomed.
12. EEPROM Mode • Factors of digital servo are changed manually.
(Each servo is turned on individually.)
• Cut-off frequency of BASS1, BASS2 and BASS3
is selected manually.
• Temperature detection terminal voltage is
measured, and the reference value is set.

(4) Once press FAST FORWARD , and determine
the displayed microcomputer TEMP input AD value.
• 'TPin##' is displayed. (## = TEMP input AD value)
(5) At the ambient temperature, determine the tempera-
ture corrected value from the temperature measure-
