• The battery charging stand and the recorder
may become hot during the charging
procedure; this, however poses no danger.
• Because of the battery’s characteristics, the
capacity of the rechargeable battery may be
smaller than normal when it is used for the
first time or after a long period of disuse. In
this case, charge and discharge the battery
several times. The normal battery life will be
restored.
• If the capacity of the rechargeable battery
drops to half the normal amount, replace with
the new one.
• If the recorder will be unused for a long time,
remove the rechargeable battery, remove the
recorder from the battery charging stand and
remove the AC power adaptor from the wall
outlet.
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 disc 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 a
disc.
• 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.
• Clean the terminals on the rechargeable
battery with a cotton swab or a soft cloth as
illustrated.
On battery
Incorrect battery usage may lead to leakage of
battery fluid or bursting battery. To prevent
such accidents, observe the following
precautions:
• Install the + and – poles of the battery
correctly.
• When the recorder is not to be used for a long
time, be sure to remove the battery.
• If a battery leak should develop, carefully and
thoroughly wipe away battery fluid from the
battery compartment before inserting new
ones.
On mechanical noise
The recorder gives off mechanical noise while
operating, which is caused by the power-saving
system of the recorder and it is not a problem.
