BAdditional information
Precautions
On safety
Do not put any foreign objects in the DC IN
1.5V 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.
Polarity of the plug
• If you are not going to use this player for a
long time, be sure to disconnect the power
supply (AC power adaptor, dry battery, or
rechargeable battery). To remove the AC
power adaptor from the wall outlet, grasp
the adaptor plug itself; never pull the cord.
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.
• Remove the rechargeable battery when the
unit is not to be used for a long time. Do
not carry the rechargeable battery in your
pocket or a bag, etc., with metallic objects
such as key rings.
On the battery case attachment
terminals on the main unit
• Do not short-circuit the battery case
attachment terminals on the main unit with
metallic objects, etc., when the
rechargeable battery is inserted, as this
may cause heat and can be dangerous.
• When carrying the player in a bag, be sure
to put it in the supplied carrying pouch.
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 touch the internal disc directly.
Forcing the shutter open may damage the
internal disc.
• Do not place the cartridge where it will be
subjected 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 or
ejecting an MD.
On dry batteries and the battery
carrying case
Incorrect battery usage may lead to leakage of
battery fluid or bursting batteries. To prevent
such accidents, observe the following
precautions:
• Install batteries with the + and – poles
aligned correctly.
• Do not try to recharge dry 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.
• Do not carry the dry battery in your pocket
or a bag, etc., with metallic objects such as
key rings. The terminals of the battery or
the battery carrying case may heat up from
a short-circuit and can be dangerous.
On mechanical noise
The player gives out mechanical noise while
operating, which is caused by the power-
saving system of the player. This is not a
malfunction.
If you have any questions or problems
concerning your player, please consult your
nearest Sony dealer.
