dangerous traffic hazard and may be  
illegal. Remember to obey all of the  
safety rules in your area.  
Avoid using or leaving the unit in the  
following places.  
Places exposed to direct sunlight for  
many hours (especially in cars with the

Notes about the rechargeable battery  
A rechargeable lithium-ion battery is  
the only kind that can be used.  
Since the rechargeable battery is  
vulnerable to damage, please note the  
following.  
Do not carry the battery in your pocket  
or in a bag together with metal objects  
(keys, coins, jewelry, etc.).  
The battery may short out and generate  
significant amounts of heat.  
Do not short-circuit the terminals as  
they will become very hot and will dam-  
age the battery.  
Even if the battery supplied with the  
unit is not used, you should charge it at  
least once every three months because  
of the special quality of this battery.  
The rechargeable battery can be  
charged approximately 300 times.  
Do not use any battery other than that  
specified. Use of other batteries may  
cause malfunctions.  
When the operating time is reduced to  
about half the normal amount of time,  
even after a full charge is performed,  
replace the battery with a new one.  
When charging or when using the re-  
chargeable battery, use it within an am-  
bient temperature range of 41°F - 95°F  
(5°C - 35°C ).  
Do not dip the battery in water, do not  
dispose of it in a fire, and do not take it  
apart.  
To avoid damaging the battery and  
shortening its service life, please note  
the following.  
Do not drop or subject the battery to  
shock.  
If the rechargeable battery is used in a  
cold environment, the operating time  
will decrease.  
Do not insert objects (metal etc.) into  
the battery compartment of this product  
or into the rechargeable battery. Do not  
get the terminals dirty. If the rechar-  
geable terminals are dirty, the opera-  
ting time may be shortened or it may  
not be possible to charge the battery.

AC power  
Cautions:  
While you are using the rechargeable  
battery and the alkaline battery at the  
same time, do not remove either of  
them. If you do, playback will stop, and  
the power may be disconnected.  
Do not replace the battery or the re-  
chargeable battery during operation.  
Do not use rechargeable batteries  
(nickel-cadmium battery etc.) in the  
battery case.  
If the unit is not used for a long period  
of time, remove the battery. (Even if the  
power is turned off, the battery will  
drain slowly but continuously.)  
Be sure to hold the plug when removing  
it. If you pull on the cord, it may break,  
or the unit may malfunction.

Connect the cord from the AC adaptor  
to the DC IN 5V jack on the main unit.  
Plug the AC adaptor into an AC outlet.  
Notes:  
If there is an electrical storm in your  
vicinity, unplug the AC adaptor from the  
AC outlet.  
When the unit is not in use for extended  
periods, remove the AC adaptor from  
the AC outlet.  
Never use an AC adaptor other than  
the one specified. Otherwise, malfunc-  
tions or serious safety hazards may re-  
sult.  
Do not use any car adaptor except for  
the optionally available AD-CA20X.  
For information about the battery life,  
see the battery item in the SPECIFICA-  
TIONS on page 20.  
Do not bend, twist or tie the power cord  
or put heavy objects on top of it.  
This unit should only be used within the  
range of 32°F - 104°F (0°C - 40°C).

(Resume function). However, if the Mini-  
Disc is removed and reinserted, playback  
will start from the first track.  
When using the unit with just the  
battery in the battery case:  
The auto-play function will not work.  
When the sound is distorted:  
If the volume is too high while the bass  
is being emphasized, the sound may be  
distorted, depending on the music on  
the track. If this happens, decrease the  
bass level or lower the volume level.  
If the volume is increased to “23" or  
higher, the bass level will be adjusted  
automatically.  
To start playback, hold down the  
/
(
) button for about 1 second.  
Even if a MiniDisc is replaced while the  
power is turned off, the random or re-  
peat play settings will remain un-  
changed in memory.  
(This is done to reduce the distortion in  
the sound.)  
Precautions when making connec-  
tions:  
Cautions:  
Do not use any remote control unit, ex-  
cept for the one included with this unit.  
Insert each plug securely, all the way  
in.  
When the unit is not to be used imme-  
diately after a MiniDisc has been in-  
serted, or when you plan to carry the  
unit, turn off the power or cancel the  
auto-play function. Otherwise, the auto-  
play function will be activated and the  
battery will run down.  
Be sure to hold the plug when removing  
it. If you pull on the cord, it may break,  
or the unit may malfunction.  
When a MiniDisc is inserted, if any re-  
sistance is felt, do not force the Mini-  
Disc into the unit. It may cause more  
problems. If resistance is felt, remove  
the MiniDisc and try reloading it.  
Since the main unit and the AC adaptor  
can heat up during use, you should  
avoid allowing the unit to be in direct  
contact with your skin for any length of  
time.  
Interrupted sound:  
This product is designed to eliminate  
interruptions in the sound which can be  
caused by vibrations. However, if the  
unit is continuously exposed to vibra-  
tions or mechanical shock, the sound  
may be interrupted momentarily.  
Note while in the playback mode:  
If you do any of the following during play-  
back, the volume and the tone settings may  
not be stored correctly.  
When using the unit with  
adaptor:  
a
car  
Plug or unplug the AC adaptor.  
When switching off the ignition during  
playback, the power to this unit will also  
be turned off. When the ignition is  
switched on, playback will start from the  
beginning of the track where playback  
was halted (Resume auto-play func-  
tion). However, the power to the unit  
may not be turned off when the ignition  
is turned off, depending on the type of  
car.  
Remove the rechargeable battery or  
the alkaline battery.  
Plug or unplug the car adaptor or turn  
off the car’s ignition key.

WHAT IS A MINIDISC?  
A MiniDisc is a disc inside a protective  
cartridge. You can handle it freely without  
worrying about dust, fingerprints, etc.  
However, if dust enters the opening of the  
cartridge, or there is excessive dirt on the  
cartridge, or the cartridge becomes  
warped, you may experience malfunc-  
tions. Please note the following.  
Where not to store discs  
Do not store discs in places with high tem-  
peratures or humidity. Specifically, do not  
leave discs in places exposed to direct  
sunlight or in cars with the doors and win-  
dows closed.  
Do not leave discs in places where sand  
or dust can get into the cartridge easily  
(e.g., beaches).  
Handling the MiniDisc

Do not open the shutter or touch the disc  
directly.  
If the shutter is opened forcibly, it may  
break.  
label  
When attaching a label to an MD cartridge,  
be sure to note the following. If the label is  
not attached properly, the MiniDisc may  
jam inside the unit and it may not be  
possible to remove it.  
Disc  
Shutter  
Cartridge  
If the label peels off  
or partially lifts away,  
replace it with a new  
one.  
Do not put a new  
label on top of an  
existing one.  
Attach the label only in the specified  
location. (If it is not within the specified  
area, it may cause the disc to jam in the  
unit.)  
Never disassemble a MiniDisc.  
Regular cleaning  
If the surface of the cartridge becomes  
dusty or dirty, clean it with a dry cloth.  
TROUBLESHOOTING  
Moisture condensation  
In the following cases, condensation  
may form inside the unit.  
When the unit has condensation inside,  
the disc signals cannot be read, and the  
unit may not function properly.  
If this happens, remove the disc.  
The condensation should evaporate in  
approximately 1 hour. The unit will then  
function properly.  
Shortly after turning on a heater.  
When the unit is placed in a room  
where there is excessive steam or  
moisture.  
When the unit is moved from a cool  
place to a warm place.
