Precautions

On safety

Do not put any foreign objects in the DC IN 6 V jack.

On power sources

• Use house current, lithium ion rechargeable battery, two LR6 (size AA) batteries, 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 batteries, 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.
• For use in the car: Use the CPA-8 or CPA-9 car connecting pack and the DCC-E260 car battery cord (not supplied).

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

• 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 install new and used batteries or different kinds of batteries together.
• Do not try to recharge dry batteries.
• 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.

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. To record again, slide the tab back so the tab is visible.

Back of the MD

Note on digital recording

This recorder uses the Serial Copy Management System, which allows only first-generation digital copies to be made from premastered software. You can only make copies from a home-recorded MD by using the analog (line out) connections.

Troubleshooting

Should any problem persist after you have made these checks, consult your nearest Sony dealer.

Symptom	Cause/Solution
The recorder does not work or works poorly.	Audio sources may not be securely connected.➢ Disconnect the audio sources once and connect them again (pages 6,11).Moisture has condensed inside the recorder.➢ Take the MD out and leave the recorder in a warm place for several hours until the moisture evaporates.The rechargeable battery or dry batteries are weak (☐ or “LOW BATT” flashes).➢ Charge the rechargeable battery or replace the dry batteries (pages 25, 26).The rechargeable battery or dry batteries have been installed incorrectly.➢ Install the batteries correctly (page 26).You pressed a button while the disc indication was rotating quickly.➢ Wait until the indication rotates slowly.The recording volume is too low.When recording digitally from a portable CD player, you did not use AC power or did not disable the anti-skip function such as ESP (page 11).The analog recording was made using a connecting cord with an attenuator.➢ Use a connecting cord without an attenuator (page 6).The AC power adaptor was unplugged during recording or a power outage occurred.While operating, the recorder received a mechanical shock, too much static, abnormal power voltage caused by lightning, etc.➢ Restart the operation as follows.1 Disconnect all the power sources.2 Leave the recorder for about 30 seconds.3 Connect the power source.
No sound comes through the headphones.	The headphones plug is not firmly connected.➢ Plug in the plug of the headphones firmly to the remote control. Plug in the plug of the remote control firmly to ☐/REMOTE.Volume is too low.➢ Adjust the volume by pressing VOLUME +/- (VOL +/- on the remote controller).AVLS is on.➢ Slide AVLS to NORM (page 18).
An MD is not played from the first track.	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.
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.
Sound has a lot of static.	Strong magnetism from a television or such device is interfering with operation.Move the recorder away from the source of strong magnetism.
Cannot find the track marks.	You pressed after pressing or .Press before pressing or .
Charging the rechargeable battery does not start.	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.
The clock loses time or the display flashes.The recording date was not stamped onto the disc.	The built-in battery for the clock is weak.Connect the AC power adaptor to DC IN 6 V on the recorder and the wall outlet to charge the built-in battery. After charging, set the clock again (page 16). Note that the clock normally loses about 2 minutes per month.
The lid does not open.	The power sources have been disconnected during playback, or the batteries have been exhausted.Set the power sources again, or replace the exhausted batteries with new ones.

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	Cause
“TR FULL” appears even before the disc has reached the maximum recording time (60 or 74 minutes).	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.
“TR FULL” appears even before the disc has reached the maximum track number or recording time.	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.
Track marks cannot be erased.	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.
The remaining recording time does not increase even after erasing numerous short tracks.	Tracks of under 12 seconds in length are not counted and so erasing them may not lead to an increase in the recording time.
The total recorded time and the remaining time on the disc may not total the maximum recording time (60 or 74 minutes).	Recording is done in minimum units of 2 seconds each, no matter how short the material. Even if the last unit of recording is less than 2 seconds, it is counted as a unit of 2 seconds. Then 2 seconds’ space is put before recording starts again to prevent the last unit of the previous track from being erased. The contents recorded may thus be shorter than the maximum recording capacity.
The edited tracks may exhibit sound dropout during search operations.	The fragmentation of data may cause sound dropout while searching because the tracks are played in higher speed than normal playback.

What is an MD?

How MiniDisc works

MiniDisc (MD) comes in two types: premastered (prerecorded) and recordable (blank). Premastered MDs, recorded at music studios, can be played back almost endlessly. However, they can't be recorded on or over like cassette tapes. To record, you must use a "recordable MD".

Premastered MDs

Premastered MDs are recorded and played like regular CDs. A laser beam focuses on the pits in the surface of the MD and reflects the information back to the lens in the recorder. The recorder then decodes the signals and plays them back as music.

Simple diagram with a square frame and an upward arrow, no text or symbols present.

Recordable MDs

Recordable MDs, which use magneto-optical (MO) technology, can be recorded again and again. The laser inside the recorder applies heat to the MD, demagnetizing the magnetic layer of the MD. The recorder then applies a magnetic field to the layer. This magnetic field corresponds exactly to the audio signals generated by the connected source. (The north and south polarities equate to digital "1" and "0".) The demagnetized MD adopts the polarity of the magnetic field, resulting in a recorded MD.

How the MiniDisc got so small

The 2.5-inch MiniDisc, encased in a plastic cartridge that looks like a 3.5-inch diskette (see illustration above), uses a new digital audio compression technology called ATRAC (Adaptive TRansform Acoustic Coding). To store more sound in less space, ATRAC extracts and encodes only those frequency components actually audible to the human ear.

Quick Random Access

Like CDs, MDs offer instantaneous random access to the beginning of any music track. Premastered MDs are recorded with location addresses corresponding to each music selection. Recordable MDs are manufactured with a “User TOC Area” to contain the order of the music. The TOC (Table of Contents) system is similar to the “directory management system” of floppy disks. In other words, starting and ending addresses for all music tracks recorded on the disc are stored in this area. This lets you randomly access the beginning of any track as soon as you enter the track number (AMS), as well as label the location with a track name as you would a file on a diskette.

Shock-Resistant Memory

One major drawback of optical read systems is that they can skip or mute when subjected to vibration. The MD system resolves this problem by using a buffer memory that stores audio data.
