About the DSP TYPE-R for ATRAC
“TYPE-R” is a high-level Sony specification used in the Digital Signal
Processor (DSP), which is heart of the MiniDisc sound. This technology gives
the MiniDisc recorder twice the signal processing capability as previous
MiniDisc Walkman models, producing a sound quality close to that of
MiniDisc decks. This unit supports the “TYPE-R” function only during
recording or playback in normal stereo mode. It does not support this function
in MDLP mode.
Notes
• 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, 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

• The level of the recorded sound is adjusted automatically.
• You can monitor the sound during recording. Connect the supplied
headphones/earphones with remote control to i and adjust the volume by

Using Auto Time Stamp to add track marks while
recording
When the elapsed recording time exceeds the time interval for
Auto Time Stamp:
The recorder adds track marks at the point you set the time interval
and from that point the recorder adds a track mark whenever the time
interval has elapsed.
Example: Eight minutes of recording has been completed when the
Auto Time Stamp time interval is set to 5 minutes.
A track mark will be added at the 8-minute point (after the start of
recording) and after each 5-minute interval thereafter.
When the time interval set for Auto Time Stamp exceeds the
elapsed recording time:
The recorder adds track marks when the set Auto Time Stamp time
interval has elapsed.
Example: Three minutes of recording has been completed when the
Auto Time Stamp time interval is set to 5 minutes.
A track mark will be added at the 5-minute point (after the start of
recording) and after each 5-minute interval thereafter.

Additional information
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 (SG) 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/earphones
Road safety
Do not use headphones/earphones 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/earphones 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.
• Attach the supplied MD label only in the space designated for it on the disc.
Do not stick it on any other disc surface.
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.
• To obtain the best sound quality, use a dry cloth to wipe the plugs of the
headphones/earphones or the remote control. Dirty plugs may cause sound
distortion or intermittent breaks in the sound.
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 battery 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.
D6ow0nload from Www.Somanuals.com. All Manuals Search And Download.
• If a battery leak should develop, carefully and thoroughly wipe away battery
fluid from the battery compartment before inserting new ones.

Explanations
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.
The meaning of “no sound”
“No sound” describes a recorder condition in which the input level is
about 4.8 mV during analog input or less than –89 dB during optical
(digital) input (with 0 dB as full bit (the maximum recordable level for a
MiniDisc)).

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.
