If the recording does not start
Make sure the recorder is not locked (page 12). Make sure the MD is not record-protected (page 46). Premastered MDs cannot be recorded over.
For long recordings, it is recommended that you power the recorder from a house current using an optional AC power adaptor ACE30HG (page 43). The lid will not open during recording or until TOC Edit disappears from the display after the recording has completed. If the power supply is disrupted (i.e. the batteries are removed or becomes exhausted or the optional AC power adaptor is disconnected) during a recording operation, or while TOC Edit appears in the display, then it will not be possible to open the lid until power is restored. Data Save or TOC Edit flashes while data of the recording (the tracks start and end points, etc.) is being recorded. Do not move or jog the recorder or disconnect the power source while the indication is flashing in the display. If you do, the material recorded up to that point will not be saved to the disc. When you record through the microphone, the various sounds made by the recorder may also be recorded. The built-in microphone do not operate whenever an optional microphone is connected into the MIC (PLUG IN POWER) jack on the recorder. The built-in microphone do not operate whenever an optical cable or a line cable (not supplied) is connected into the LINE IN (OPTICAL) jack on the recorder.

Various ways of recording
Long-time recording (MDLP)
Select each recording mode according to the recording time that you want. Stereo recording is possible at 2 times (LP2) or 4 times (LP4) the normal (SP) recording time. Monaural recording at 2 times normal recording time is also possible. MDs recorded in monaural or MDLP mode can be played back only on MD players or recorders with monaural or MDLP playback mode.

Press REC. For other operations on recording, see Recording an MD right away! (page 13).
If you record in SP, LP2, or LP4 mode using an externally connected stereo microphone (not supplied) or other stereo equipment connected to the LINE IN (OPTICAL) jack, the recording will be stereo. If you record with the built-in microphone, the recording will be monaural (the same sound is recorded to the left and right channels). The recording mode can be changed during recording pause. When you change the recording mode, a track mark is automatically added at that point. Audio components that support the LP2 or LP4 modes are indicated by the or logo marks.
Insert a recordable disc. Press REC MODE repeatedly until desired recording mode lights up in the display. Each time you press the button, A changes as follows.
It is recommended that you use the AC power adaptor (not supplied) for long recordings. During monaural recording of a stereo sound source connected through the digital (optical) input jack, you can still monitor the recorded sound in stereo by using headphones/ earphones connected to the i jack. When you record in LP4 mode, momentary noise may be produced on very rare occasions with certain sound sources. This is because of the special digital audio compression technology that enables a recording time 4 times longer than normal. If noise is produced, it is recommended that you record in SP or LP2 mode to obtain better sound quality.

There is no digital signal from the portable CD player. , When recording digitally from a portable CD player, use the AC power adaptor and disable the anti-skip function (such as ESP) on the CD player (page 21). The analog recording was made using a connecting cord with an attenuator. , Use a connecting cord without an attenuator (page 22). The power sources was disconnected or a power outage occurred during recording. , The recording result is not recorded on the disc. Make recording again. The premastered MD is inserted. , Replace to the recordable MD. The remaining recordable time on the disc is 12 seconds or less (DISC FULL appears). , Replace the disc. Due to the special digital audio compression technology used in LP4 stereo mode, momentary noise may occur on very rare occasions with certain sound sources. , Record in SP or LP2 mode (page 18). The lid does not open until TOC Edit disappears in the display.
Momentary noise is heard when recording.
The lid does not open after recording.
Symptom TR FULL appears even before the disc has reached the maximum recording time (60, 74, or 80 minutes) and the recording cannot be done.
Cause/Remedy This is due to the MiniDisc system limitation.When 254 tracks have been recorded on the disc, TR FULL appears regardless of the total recorded time. More than 254 tracks cannot be recorded on the disc. , To continue recording, erase unnecessary tracks.

This is due to the MiniDisc system limitation. Tracks of under The remaining 12 seconds, 24 seconds, 48 seconds in length are not counted recording time does and so erasing them may not lead to an increase in the not increase even after recording time. erasing numerous short tracks. The total recorded This is due to the MiniDisc system limitation. Normally, time and the remaining recording is done in minimum units of approximately 2 time on the disc may seconds (in stereo), 4 seconds (in LP2 stereo mode or not total the maximum monaural mode), or 8 seconds (in LP4 stereo mode). When recording time (60, 74, recording is stopped, the last unit of recording always uses this or 80 minutes). unit of 2 seconds, 4 seconds, or 8 seconds even if the actual recording is shorter. Likewise, when recording is restarted after the stop, the recorder will automatically insert a blank space amounting to 2 seconds, 4 seconds, or 8 seconds before the next recording. (This is to prevent accidental erasing of a previous track whenever a new recording is started). Therefore, the actual recording time will decrease whenever a recording is stopped; a maximum of 6 seconds, 12 seconds, or 24 seconds compared to the potential recording time for each stop. TR FULL appears even before the disc has reached the maximum track number or recording time. This is due to the MiniDisc system limitation. Repeated recording and erasing may cause fragmentation and scattering of data. Although those scattered data can be read, each fragment is counted as a track. In this case, the number of tracks may reach 254 and further recording is not possible. To continue recording, erase unnecessary tracks. , To continue recording, erase unnecessary tracks.

The power source has been disconnected or a power outage has occurred during editing. , The editing done to that point is not saved to the disc. Do the editing operation again. This is due to the MiniDisc system limitations. When the data of a track is fragmented, the track mark of a fragment under 12 seconds long (recorded in stereo), 24 seconds long (recorded in LP2 stereo mode or monaural mode), or 48 seconds long (recorded in LP4 stereo mode) cannot be erased. You cannot combine a track recorded in stereo and a track recorded in monaural; nor can you combine a track recorded with digital connection and a track recorded with analog connection.

MZ-B10 SECTION 1 SERVICING NOTES
NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT The laser diode in the optical pick-up block may suffer electrostatic break-down because of the potential difference generated by the charged electrostatic load, etc. on clothing and the human body. During repair, pay attention to electrostatic break-down and also use the procedure in the printed matter which is included in the repair parts. The flexible board is easily damaged and should be handled with care. NOTES ON LASER DIODE EMISSION CHECK Never look into the laser diode emission from right above when checking it for adjustment. It is feared that you will lose your sight. NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK (LCX-5R) The laser diode in the optical pick-up block may suffer electrostatic break-down easily. When handling it, perform soldering bridge to the laser-tap on the flexible board. Also perform measures against electrostatic break-down sufficiently before the operation. The flexible board is easily damaged and should be handled with care. In performing the repair with the power supplied to the set, removing the MAIN board causes the set to be disabled. In such a case, make a solder bridge to short SL802 (OPEN CLOSE) on the MAIN board in advance. MAIN Board (Side B)
