If the recording does not start
Make sure the recorder is not locked (page 23). Make sure the MD is not record-protected (page 31). Premastered MDs cannot be recorded over.
For models supplied with the AC plug adaptor
If the AC power adaptor (supplied with the European, Chinese and Argentine models only) does not fit the wall outlet, use the AC plug adaptor.
If the power supply is disrupted (i.e. the battery is removed or becomes exhausted or the AC power adaptor is disconnected) during a recording or editing operation, or while Edit appears in the display, then it will not be possible to open the lid until power is restored. You can make a digital recording only from an optical type output. When recording from a portable CD player, set the CD player to pause, and then do the recording procedure on the recorder. Note the following when recording from a portable CD player: Some portable CD players may not be capable of digital out unless powered by the AC power. Connect the AC power adaptor to the portable CD player and use it on AC power as the power source. Disable any anti-skip function (such as ESP*) on the portable CD player. Electronic Shock Protection

LINE IN (OPTICAL) jack is for both digital and analog input. The recorder automatically recognizes the type of line cable and switches to digital or analog input. The level of the recorded sound is adjusted automatically. You can monitor the sound during recording. Connect the supplied headphones/earphones to i and adjust the volume by pressing VOL +/. This does not affect the recording level.

G-PROTECTION function

The G-PROTECTION function has been developed to provide excellent protection against sound skipping during many active uses. This function provides a higher level of shock protection during playback than the traditional one.
If the play does not start
Make sure the recorder is not locked (page 23).
Playback will switch automatically between stereo and monaural according to the sound source.
Sound may skip if: the recorder receives stronger continuous shock than expected. a dirty or scratched MiniDisc is played.
Various ways of recording
Two ways of connecting to a sound source
The input jack of this recorder works as both digital and analog input jacks. Connect the recorder to a CD player or a cassette recorder using either digital (optical) input or analog (line) input. To record, see Recording an MD right away! (page 10) to record using digital (optical) input, and Recording with analog input (line cable required) (page 16) to record using analog (line) input. Difference between digital (optical) and analog (line) inputs Difference Connectable source Usable cord Digital (optical) input Equipment with a digital (optical) output jack Optical cable (with an optical or an optical-mini plug)(page 10) Analog (line) input Equipment with an analog (line) output jack Line cable (with 2 phono plugs or a stereo-mini plug)(page 16) Analog Even when a digital source (such as a CD) is connected, the signal sent to the recorder is analog.

You can erase unnecessary marks after recording. (Erasing a track mark, page 26). Recorded sound level Same as the source.

In this case, play the source in normal play mode. when recording BS or CS programs through digital (optical) input.

Recording for long times

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 recording time. MDs recorded in monaural, LP2 or LP4 mode can be played back only on MD players or recorders with monaural, LP2 or LP4 playback mode.

Precautions

On safety
Do not put any foreign objects in the DC IN 3V jack.

Road safety

Symptom There is no recording on the MD after a recording operation. The lid does not open. Volume cannot be turned up. No sound comes through the headphones/ earphones. An MD is not played from the first track. Playback sound skips. Sound has a lot of static. Cannot find the track marks. The disc cannot edit on other component. Momentary noise is heard.
Cause/Solution The AC power adaptor was unplugged or a power outage occurred during recording.
The battery have been exhausted. , Replace the exhausted battery with new ones. AVLS is on. , Set AVLS to OFF (page 22). The headphones/earphones plug is not firmly connected. , Plug in the plug of the headphones/earphones firmly to i. Volume is too low. , Adjust the volume by pressing VOL +/. Disc playing stopped before it came to the last track. , Press. repeatedly or open and close the lid once to go back to the beginning of the disc, and restart playing after checking the track number in the display. The recorder is placed where it receives continuous vibration. , Put the recorder on a stable place. A very short track may cause sound to skip. Strong magnetism from a television or such device is interfering with operation. , Move the recorder away from the source of strong magnetism. You pressed X after pressing. or >. , Press X before or pressing. or > (page 27). The component does not support LP2 and LP4. , Edit on other component that support LP2 and LP4. Due to the special digital audio compression technology used in LP4 mode, momentary noise may occur on very rare occasions with certain sound sources. , Record in normal stereo or LP2 mode.

System limitations

The recording system in your MiniDisc recorder is radically different from those used in cassette and DAT decks and is characterized by the limitations described below. Note, however, that these limitations are due to the inherent nature of the MD recording system itself and not to mechanical causes. Symptom TrFULL appears even before the disc has reached the maximum recording time (60, 74, or 80 minutes). TrFULL appears even before the disc has reached the maximum track number or recording time. Track marks cannot be erased. The remaining recording time does not increase even after erasing numerous short tracks. Cause When 254 tracks have been recorded on the disc, TrFULL appears regardless of the total recorded time. More than 254 tracks cannot be recorded on the disc. To continue recording, erase unnecessary tracks.
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. 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 mode or monaural mode), or 48 seconds long (recorded in LP4 mode) cannot be erased. You cannot combine tracks recorded in different recording modes, e.g., 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. Tracks of under 12 seconds, 24 seconds, or 48 seconds in length are not counted and so erasing them may not lead to an increase in the recording time. Normally, recording is done in minimum units of approximately 2 seconds (in stereo), 4 seconds (in LP2 mode or monaural), or 8 seconds (in LP4 mode). When recording is stopped, the last unit of recording always uses this 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 by a maximum of 6 seconds, 12 seconds, or 24 seconds. The fragmentation of data may cause sound dropout while searching because the tracks are played in higher speed than normal playback.

The total recorded time and the remaining time on the disc may not total the maximum recording time (60, 74, or 80 minutes).
The edited tracks may exhibit sound dropout during search operations.
