The unit may have the following symptoms while recording or editing. The unit is not malfunctioning.
MiniDisc System Limitations
SYMPTOM
“DISC FULL” or “TOC FULL” appearseven though the MiniDisc still has re-cording time left.
The remaining recording time does notincrease even though you erased tracks.
The total of the recorded time and theremaining time does not match the maxi-mum recordable time.
Combine function does not work.
Sound skips in fast reverse/forward.
A track number is created in the middleof a track.
LIMITATIONS
More than 255 tracks (maximum) cannot be recorded regardless of the re-cording time.If the MiniDisc is recorded or edited repeatedly or if it has scratches (record-ing skips scratched parts), you may not be able to record the maximumtracks above.
The unit does not count non-recorded portions that last 12 or fewer secondsto display the remaining recording time. The time may not increase even ifyou 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 displayedtime.
A MiniDisc on which recording and editing are repeated may not allow thecombine function.
One track is divided and recorded in separate places on a repeatedly re-corded or edited MiniDisc.Sound may skip.
A track number may be created if there are scratches or dust on the MiniDisc.
TroubleshootingMany potential “problems” can be resolved by the owner without calling a service technician.If something seems to be wrong with this product, check the following before calling your authorized SHARP dealer orservice center.
The unit does not turn on.
No sound is heard from the head-phones.
When the operation buttons arepressed, the unit does not respond.
Some sounds are skipped.
The MiniDisc cannot be ejected.
Recording and editing are impossible.

EEPROM (IC402) writing procedure1. Procedure to replace EEPROM and write initial value of microcomputer in EEPROM
(1) Replace EEPROM.(2) Refer to the latest EEPROM data list.(3) Press the Display button, ENTER button and Play button to start the test mode.(4) Version display
[ V e r . ]
EEPROM version (b ~ Z)Microcomputer ROM version
(5) The whole LCD lights.(6) Test mode stop state.
[ T E S T ](7) Press the "BASS" button, and press twice the "SKIP DOWN" button.
[ E E P R O M ](8) Perform the operation to display "EEPROM SETTING MODE CHART", compare the EEPROM DATA LIST with the display,
and set according to the EEPROM DATA LIST with the VOL UP or VOL DOWN key. (9) Set the temperature reference. (Refer to the Temperature Reference Setting Method.) (10) Set according to the EEPROM DATA LIST. (11) Press the Stop button.
[ T E S T ] (12) Press the Stop button. (13) After data is written in EEPROM, turn off power . (14) Restore protection of EEPROM.
2. Temperature reference setting method[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) Start the EEPROM mode 'Temp' menu. • Key operation in order of BASS, SKIP-DOWN x 2 times, PLAY, PLAY in the test mode STOP state. • 'TM$$%%' is displayed. ($$= Temperature code, %% = Temperature reference)(3) Once press SKIP-UP, and determine the displayed microcomputer TEMP input AD value. • 'TPin##' is displayed. (## = TEMP input AD value)(4) At the ambient temperature, determine the temperature corrected value from the temperature measurement value
correction table.(5) Determine the temperature reference, using the following formula. • Temperature reference = Microcomputer TEMP input AD value + Temperature corrected value(6) Set the temperature reference value by button operation , and check whether the temperature code indication corresponds to "Temperature
Code Identification Table".

NOTES ON SCHEMATIC DIAGRAM
• Resistor:To differentiate the units of resistors, such symbol as K andM are used: the symbol K means 1000 ohm and the symbolM means 1000 kohm and the resistor without any symbol isohm-type resistor. Besides, the one with “Fusible” is a fusetype.
• Capacitor:To indicate the unit of capacitor, a symbol P is used: thissymbol P means micro-micro-farad and the unit of thecapacitor without such a symbol is microfarad. As to electro-lytic capacitor, the expression “capacitance/withstand volt-age” is used.(CH), (TH), (RH), (UJ): Temperature compensation(ML): Mylar type
• The indicated voltage in each section is the one measuredby Digital Multimeter between such a section and the chas-sis with no signal given.
• Parts marked with “ ” ( ) are important formaintaining the safety of the set. Be sure to replace theseparts with specified ones for maintaining the safety andperformance of the set.
