TROUBLESHOOTING
■Moisture condensation In the following cases, condensation may form inside the unit. ●Shortly after turning on a heater. ●Whenthe unit is placed in a room where
there is excessive steam or moisture.
●When the unit is moved from a cool
place to a warm place.
When the unit has condensation inside, the disc signals cannot be read, and the unit may not function properly. ●If this happens, remove the disc.
The condensation should evaporate in
approximately 1 hour. The unit will then function properly.
Many potential “problems” can be resolved by the owner without calling a service techni- cian. If something seems to be wrong with this product, check the following before calling your authorised SHARP dealer or service centre.
■If trouble occurs When this product is subjected to strong external interference (mechanical shock, excessive static electricity, abnormal sup- ply voltage due to lightning, etc.) or if it is operated incorrectly, it may malfunction. If such a problem occurs, do the following: 1. Unplug the AC adaptor from the AC
socket.
2. Remove the battery. 3. Leavethe unit completelyunpoweredfor
approximately 30 seconds.
4. Plug the AC adaptor back into the AC
socket and retry the operation.
Ifstrange sounds, smell or smoke comeout of the unit or an object is dropped into the unit, remove the AC adaptor from the AC socket immediately and contact an authorised SHARP service centre.
PROBLEM CAUSE
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?
●Is the volume set too low? ●Is the earphones plugged in? ●Are you trying to play a MiniDisc with data on it instead
of a MiniDisc containing music?
●Is the unit in the hold mode? ●Is the battery exhausted? ●Is the battery exhausted? ●Is the unit being subjected to excessive vibration? ●Has the track number or character information been
written on the disc yet?
●Is the unit in the recording or editing mode? ●Is the MiniDisc protected against accidental erasure? ●Is the unit connected properly to the other equipment? ●Is the AC adaptor unplugged or did a power failure oc-
cur whilst recording or editing?
●Is the unit in the hold mode? ●Isan optical signal being output from the external equip-
ment? Read the operation manual for the external equipment.
No sound is heard from the earphones.
When the operation but- tons are pressed, the unit does not respond. Some sounds are skipped. The MiniDisc cannot be ejected. Recording and editing are impossible.

Whenthenumberoftracksusedreaches the limit, regardless of the remaining re- cording time, further recording will be impossible. (Maximum number of tracks: 255) If a MiniDisc has been recorded or ed- ited repeatedly or if a MiniDisc has scratches on it, it may not be possible to recordthemaximumnumberoftrackson it. If there are scratches on a disc, the unit willautomaticallyavoid recording in those areas.Therecordingtime will bereduced. When the remaining recording time of a disc is displayed, short tracks less than 12 seconds long may not be included in the total. For MiniDiscs on which repeated record- ing and editing operations were per- formed, the COMBINE function may not work. A cluster (about 2 seconds) is normally the minimumunitofrecording.So,evenifatrack is less than 2 seconds long, it will use about 2 seconds of space on the disc. Therefore, the time actually available for re- cordingmaybelessthantheremainingtime displayed. If there are scratches on discs, those sec- tionswillbeautomaticallyavoided(norecord- ing will be placed in those sections). There- fore, the recording time will be reduced. For MiniDiscs on which repeated record- ing and editing were performed, some soundsmaybe skipped whilst cueing and reviewing. If there are scratches or dust on a MiniDisc,thetrack numbers following that track will be increased by one.
MINIDISC SYSTEM LIMITATIONS
MiniDiscs are recorded using a different system than is used for cassette tapes or DAT recordings. Therefore, the following conditions may be encountered, depending on how the disc has been recorded or edited. These are due to system limitations, and should be considered normal.
Even if the maximum recording time of a MiniDisc has not been reached, “DISC FULL” or “TOC FULL” may be displayed. Even if the number of tracks and the recording time have not reached the limit, “DISC FULL” may be displayed. Even if several short tracks are erased, the remaining recording time may not show an increase. Two tracks may not be combined in editing. The total of the recorded time and time remaining on a disc may not add up to the maximum possible recording time. When recorded tracks are played back using the cue and review op- erations, some sounds may be skipped. A track number can be created in the middle of a track.
