2
Insert an alkaline battery into the battery
case.
3
Attach the battery case to the portable MD.
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

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 recording time left.
The remaining recording time does not
increase even though you erased
tracks.
The total of the recorded time and the
remaining time does not match the maximum recordable time.
Combine function does not work.
Sound skips in fast reverse/forward.
A track number is created in the middle
of a track.
More than 255 tracks (maximum) cannot be recorded regardless of
the recording time. If the MiniDisc is recorded or edited repeatedly or
if it has scratches (recording skips scratched parts), you may not be
able to record the maximum tracks above.
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.
One cluster (approximately 2 seconds) is the minimum unit for recording. For example, a 3-second track uses 2 clusters (approximately 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.)
A MiniDisc on which recording and editing are repeated may not allow the combine function.
If one track is divided and recorded in separate places on a repeatedly recorded or edited MiniDisc, sound may skip.
A track number may be created if there are scratches or dust on the
MiniDisc.
Troubleshooting
Many potential "problems " can be resolved by the owner wit hout calling a service techn ician. If so mething seems to 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 unit in the hold mode?
Has condensation formed inside the unit?
●
Is the unit being influenced by mechanical shock or b y
●
static electricity?
No sound is heard from the earphones.
●
Is the volume set too low?
Is the earphones plugged in?
●
●
Are you trying to pl ay a MiniDisc with data on it 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 connect ed prope rly to the other equipment?
Is the AC adaptor unplug ged or did a power f ailure 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 system.

[1] Measurement, calculation and setting procedure
(1) Set the TEST mode.
• Set TEST 1, 0 = '01', and turn on power
(or set PLAY ON in standby state).
(2) Press the MENU button, ENTER button and Play
button to start the test mode.
(3) Start the EEPROM mode 'Temp' menu.
• Button operation in order of BASS, FAST REVERSE
x 3 times, PLAY , PLAY in the test mode

• 'TM§§ ' is displayed. (§§= Temperature code,
= Temperature reference)
(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 measurement value correction table.
(6) Determine the temperature reference, using the fol-
lowing formula.
• Temperature reference = Microcomputer TEMP
input AD value + Temperature corrected value
(7) Set the temperature reference value by button opera-
tion, and check whether the temperature code indication corresponds to "Temperature Code Identification
Table".
