Precautions
On safety
• Do not put any foreign objects in the DC
IN 1.5 V jack.
On power sources
• For use in your house: Use the AC power
adaptor AC-E15L (not supplied). Do not
use any other AC power adaptor since it
may cause the player to malfunction.
• The player is not disconnected from the AC
power source (mains) as long as it is
connected to the wall outlet, even if the
player itself has been turned off.
• If you are not going to use this player for a
long time, be sure to disconnect the power
supply (AC power adaptor, dry batteries,
rechargeable batteries, 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-9 car
connecting pack and the DCC-E215 car
battery cord (not supplied).
On charging
• Be sure to use the supplied battery charger.
• Charging time may vary depending on the
battery condition.
• When you use the battery for the first time
or after a long period of disuse, the battery
life may be shorter. In this case, charge and
discharge the battery several times. The
battery life will be restored.
• If the rechargeable battery capacity
becomes half the normal life, replace it with
a new one.
On heat build-up
• Heat may build up in the player if it is used
for an extended period of time. In this case,
leave the player to cool down.
On installation
• Never use the player where it will be
subjected to extremes of light, temperature,
moisture or vibration.
• Never wrap the player in anything when it
is being used with the AC power adaptor.
Heat build-up in the player may cause
malfunction or injury.
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 player
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, temperature, moisture or
dust.
On cleaning
• Clean the player 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 and ejecting an
MD.
Notes on the 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 the batteries.
• When the player 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 player gives out mechanical noise while
operating, which is caused by the power-
saving system of the player and it is not a
trouble.
