The Sony MZ-R70 can record from an optical digital, analog, or microphone source. Optical uses a Mini-TOS plug, while the line and mic inputs use standard 1/8 plugs. If you are using a microphone with an XLR output, be sure to get an XLR to 1/8 adapter plug, available from Media Loan. To record optically, you must have a digital source with an optical output, such as a CD player. In optical recording, the level and track marks are set automatically.

Start Recording

1. Connect your source (mic, CD, etc.) 2. Press the OPEN Button (3). 3. Insert a disc (label side up) and close the cover. 4. Silde the RECORD switch (18) to the right. The unit will begin recording immediately. NOTE: To ensure that you begin recording at the end of the previous recording press the END SEARCH Button (2) before you record.
To adjust record settings, hold the PAUSE Button (9) and slide the RECORD Switch (18) to the right. More on record settings below.

Hold Function

The HOLD Switch (6), located on the bottom of the unit, is used to disable the buttons on the unit. When the HOLD Switch is activated none of the controls on the unit will respond. If you activate the HOLD Switch on the remote (34), none of the controls on the remote will respond. Neither switch affects the other device.

In addition to the i1 jack, you can connect headphones to the i2 jack as well.
Playback will switch automatically between stereo and monaural according to the sound source.
To prevent recorder malfunction, do not use a remote control that was supplied with another Sony portable MD model. The sound may skip during playback when the recorder is exposed to continuous vibration, such as while jogging.
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 6) 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 6) Digital 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.

Analog (line) input Marked automatically after more than 2 seconds of blank or low-level segment. when the recorder is paused while recording. You can erase unnecessary marks after recording (Erasing a track mark, page 43).

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.

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.

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.

Precautions

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

On power sources

Use house current, nickel cadmium rechargeable battery, LR6 (size AA) battery, or car battery. For use in your house: Use the AC power adaptor supplied with this recorder. Do not use any other AC power adaptor since it may cause the recorder to malfunction.

Polarity of the plug

The recorder is not disconnected from the AC power source (mains) as long as it is connected to the wall outlet, even if the recorder itself has been turned off. If you are not going to use this recorder for a long time, be sure to disconnect the power supply (AC power adaptor, dry battery, rechargeable battery, or car battery cord). To remove the AC power adaptor from the wall outlet, grasp the adaptor plug itself; never pull the cord.

On heat build-up

Heat may build up in the recorder if it is used for an extended period of time. In this case, leave the recorder turned off until it cools down.

On installation

Never use the recorder where it will be subjected to extremes of light, temperature, moisture or vibration. Never wrap the recorder in anything when it is being used with the AC power adaptor. Heat build-up in the recorder may cause malfunction or damage.

On the headphones

Road safety
Do not use headphones while driving, cycling, or operating any motorized vehicle. It may create a traffic hazard and is illegal in many areas. It can also be potentially dangerous to play your recorder at high volume while walking, especially at pedestrian crossings. You should exercise extreme caution or discontinue use in potentially hazardous situations.
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.

To protect a recorded MD

To record-protect an MD, slide open the tab at the side of the MD. In this position, the MD cannot be recorded or editted. To record again, slide the tab back so the tab is visible.
