PRECAUTIONS
n Important
l Do not wear your earphones when you
are crossing streets or near traffic.
l Do not use your earphones whilst driv-
ing a motor vehicle, it may create a dan-
gerous traffic hazard and may be ille-
gal. Remember to obey all of the safety
rules in your area.
l Do not play the unit at a high volume.
Hearing experts advise against ex-
tended listening at high volume levels.
l If you experience ringing in your ears,
reduce the volume or discontinue use.
n Volume setting
Reduce the volume before starting to play.
MiniDiscs, compared to ordinary cassette
tapes, have very little noise. If the volume
is adjusted according to your usual expec-
tations of noise, you may damage your
hearing due to the high volume.
n Concern for others when listen-
ing to MiniDiscs
If you are enjoying listening to music, the
sound escaping from your earphones may
annoy people around you.
If you are using the unit in particularly
crowded places (such as on trains or
buses), reduce the volume to avoid annoy-
ing people around you.
n Storing the unit
Avoid using or leaving the unit in
the following places.
l Places exposed to direct sunlight for
many hours (especially in cars with the
doors and windows closed) or near heat-
ers.

or the unit may malfunction.)
l Places exposed to water.
l Places exposed to excessive dust.
l Places where temperatures are exces-
sively high or low.
l Places (bathrooms) where the humidity
is extremely high.
l Places with strong magnetic fields such
as TVs or loudspeakers.
l Places exposed to vibration.
l Places where sand can easily enter the
inside of the unit (beaches etc.).
l If the unit is used near radio tuners or
TVs, noise and/or picture interference
may result. If you experience these prob-
lems, move the unit away from such de-
vices.

n Notes about the rechargeable battery
l A rechargeable lithium-ion battery is the
only kind that can be used. 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.
l The rechargeable battery can be
charged approximately 300 times.
l Do not use any battery other than that
specified. Use of other batteries may
cause malfunctions.
l When the operating time is reduced to
about half the normal amount of time,
even after a full charge is performed, re-
place the battery with a new one.
l When charging or when using the re
chargeable battery, use it within an am-
bient temperature range of 5 C(41 F) to
35 C(95 F).
l If the rechargeable battery is used in a
cold environment, the operating time will
be reduced.
Since the rechargeable battery is
vulnerable to damage, please note
the following.
l Do not carry the battery in your pocket
or a bag together with metal objects
(keys, coins, jewelry, etc.). The battery
may short out and generate significant
amounts of heat.
l Do not short-circuit the terminals as they
will become very hot and will damage
the battery.
l Do not dip the battery in water, do not dis-
pose 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.
l Do not drop or subject the battery to
shock.
l 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 rechargeable
terminals are dirty, the operating time
may be shortened or it may not be pos-
sible to charge the battery.
l After the rechargeable battery is charged
or used, it will get slightly warm. This is
normal.
