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. The lid does not open until TOC Edit disappears in the display.
To Record from the end of the previous recording Record partway through the previous recording Pause Remove the MD
Press END SEARCH and slide REC. N, > or. to find the start point of recording and press x to stop. Then slide REC. X1) Press X again to resume recording. x and open the lid.2) (The lid does not open while TOC Edit flashing in the display.)
track mark is added at the point where you press X again to resume recording while pausing; thus the remainder of the track will be counted as a new track. 2) Once you open the lid, the point to start recording will change to the beginning of the first track. Check the point to start recording on the display.
If the recording does not start
Make sure the recorder is not locked (page 35). Make sure the MD is not record-protected (page 56). Premastered MDs cannot be recorded over.
For models supplied with the AC plug adaptor
If the AC power adaptor 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 TOC 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, play it on AC power and disable the anti-skip function (such as ESP*).
Digital output may be disabled on some portable CD players when the player is not run on AC power.
Electronic Shock Protection
The level of the recorded sound is adjusted automatically. You can monitor the sound during recording. Connect the supplied headphones with remote control to i1 and adjust the volume by pressing VOL +/. This does not affect the recording level.
Playing an MD right away!
To use the recorder on a rechargeable battery or dry battery, see Power sources (page 51).

To start/stop recording in sync with the source player (Synchro-recording)
You can easily make digital recordings of a digital source on an MD. Before synchro-recording, make connections to the digital source with a digital cable, and insert a recordable MD.

CD players, etc.

SYNCHRO REC
Slide SYNCHRO REC on the bottom of the recorder to ON. SYNC appears in the display.

End 007

SYNC doesnt appear if optical cable is not connected to the recorder.
Slide REC to the right. The recorder stands by for recording. Play the source sound. The recorder starts recording when it receives the playing sound.
To stop recording, press x.
You cannot pause manually during synchro-recording. When there is no sound from the player for more than 3 seconds during synchro-recording, the recorder goes into the standby mode automatically. When the sound comes from the player again, the recorder resumes synchrorecording. If the recorder is kept in the standby mode for 5 minutes or longer, the recorder stops automatically.
Do not switch SYNCHRO REC after step 3. Recording may not be done properly. When recording in monaural, follow steps 1 to 3 of Recording in monaural for double the normal recording time (page 20), and then do steps 1 and 3 of synchro-recording. Even when there is no recorded sound on the sound source, there may be cases when recording does not pause automatically during synchro-recording due to the noise level emitted from the sound source. If a silent portion is encountered for 2 seconds or more during synchrorecording, a new track mark is automatically added at the point where the silent portion ends. Synchro-recording cannot be done if the connecting cord is not an optical cable, or if the cable is connected to the MIC (PLUG IN POWER) jack. You cannot adjust the recording level manually during synchro-recording.
Recording from a microphone
Connect a stereo microphone (ECM-717, ECM-MS907, ECMMS957, etc.; not supplied) to the MIC (PLUG IN POWER) jack.
Stereo microphone to MIC (PLUG IN POWER)
Insert a recordable MD and start recording. Slide REC to the right. For other operations, see Recording an MD right away! (page 6).

You cannot record through the microphone while an optical cable is connected to the LINE IN (OPTICAL) jack. The recorder automatically switches input in the following order; optical input, microphone input, and analog input. The microphone may pick up the operating sound of the recorder itself. Use the microphone away from the recorder in such cases.
Recording in monaural for double the normal recording time
For longer recordings, choose to record in monaural. The recording time becomes double the normal.

While pressing X, slide REC to the right. The recorder stands by for recording. Press ENTER, press >MENU. repeatedly until REC MODE flashes in the display, and then press ENTER again. Press >MENU. repeatedly until Mono REC flashes in the display, and then press ENTER. To switch back to stereo recording, press ENTER while Stereo REC flashes in the display. Press X again to start recording. Play the sound source.
The recorder switches back to stereo recording when you record the next time.
If you record a stereo source in monaural, the sounds from left and right will be mixed. You cannot record in monaural if SYNCHRO REC is slid to ON. If you are recording digital input, make sure to slide SYNCHRO REC to OFF before you begin recording. The MDs recorded in monaural can be played back only with an MD player/ recorder that has the monaural playing function. Sound recorded through digital (optical) input can be monitored in stereo through headphones, etc.
Adjusting the recording level manually (Manual recording)
When you record, the sound level is adjusted automatically. If necessary, you can set the level manually.

You can use the recorder on house current or as follows. In the recorder a nickel cadmium rechargeable battery NC-WMAA (supplied) LR6 (size AA) alkaline dry battery (not supplied) It is preferable to use the recorder on house current when recording for a long time.
Charging the nickel cadmium rechargeable battery
Before using the supplied NC-WMAA nickel cadmium rechargeable battery for the first time, charge it in the recorder.
Connect the supplied AC power adaptor.
to wall output AC power adaptor (supplied)
Insert the NC-WMAA into the recorder and close the lid.
Press x. Charging flashes, e appears in the display, and charging starts. Full charging of a completely discharged rechargeable battery takes about 3 hours. To cancel charging, press x.
If you press x immediately after charging has completed, charging will begin again, even though the battery is already fully charged. Charging stops when you try to operate the recorder during charging. Be sure to use the supplied AC power adaptor. Charging time may vary depending on the battery condition. When a rechargeable battery is charged for the first time or charged after a long period of disuse, battery life may be shorter than usual. Repeat discharging and recharging a few times. The battery life should return to normal. When the battery life of a fully charged rechargeable battery becomes about half the normal life, replace it. When carrying the rechargeable battery, keep it in the supplied carrying case. It is dangerous to carry the battery out of its case in your pocket or a bag together with metallic objects such as key rings, as this may cause a short circuit. Remove the rechargeable battery from the recorder when it is not to be used for a long time.

Using on a battery

The recorder accepts either a rechargeable nickel cadmium battery (supplied) or an LR6 (size-AA) alkaline dry battery. Be sure the rechargeable battery is fully charged.
Insert either a fully charged nickel cadmium rechargeable battery or a LR6 (size AA) alkaline dry battery with correct polarity. Battery life1) Batteries Recording3) Playback NC-WMAA nickel cadmium Approx. rechargeable battery 3 hours LR6 (size AA) Sony alkaline dry battery2)

Preventing hearing damage
Avoid using headphones at high volume. Hearing experts advise against continuous, loud and extended play. If you experience a ringing in your ears, reduce the volume or discontinue use.

Caring for others

Keep the volume at a moderate level. This will allow you to hear outside sounds and to be considerate of the people around you.
On the MiniDisc cartridge
When carrying or storing the MiniDisc, keep it in its case. Do not break open the shutter. Do not place the cartridge where it will be subject to light, extreme temperatures, moisture or dust.

On cleaning

Clean the recorder casing with a soft cloth slightly moistened with water or a mild detergent solution. Do not use any type of abrasive pad, scouring powder or solvent such as alcohol or benzene as it may mar the finish of the casing. Wipe the disc cartridge with a dry cloth to remove dirt. Dust on the lens may prevent the unit from operating properly. Be sure to close the disc compartment lid after inserting or ejecting an MD.

Notes on batteries

Incorrect battery usage may lead to leakage of battery fluid or bursting batteries. To prevent such accidents, observe the following precautions: Install the + and poles of the batteries correctly. Do not try to recharge dry battery. When the recorder is not to be used for a long time, be sure to remove the batteries. If a battery leak should develop, carefully and thoroughly wipe away battery fluid from the battery compartment before inserting new ones.
On the lid of the battery compartment
The lid of the battery compartment is designed to detach from the main unit when handled with great force. To reattach the lid to the main unit, follow the steps below:

Projections

1 Place the lid so that the projections on the lid aligned with the slots on the main unit.
2 Fit the projection one by one into the slot as shown in the illustration.

Note on mechanical noise

The recorder gives off mechanical noise while operating, which is caused by the power-saving system of the recorder and it is not a problem.

No sound comes through the headphones.
An MD is not Disc playing stopped before it came to the last track. played from the first 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. Playback sound skips. 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.
Symptom Sound has a lot of static.
Cause/Solution 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 43). The rechargeable battery has been inserted incorrectly or the AC power adaptor has been connected incorrectly. , Insert the battery correctly or connect the AC power adaptor correctly.
Cannot find the track marks. The rechargeable battery does not start charging.

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 TR FULL appears even before the disc has reached the maximum recording time (60, 74, or 80 minutes). TR FULL 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, 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.
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 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. Tracks of under 12 seconds in length are not counted and so erasing them may not lead to an increase in the recording time.
