Precautions
On charging
• The supplied charging stand can be
used only with this unit. No other
model can be charged using this stand.
• Remove the AC power adaptor from
the wall outlet as soon as possible after
the rechargeable battery has been
charged. Overcharging may damage
the rechargeable battery.
• The charging stand and the
rechargeable battery may become
warm during charging, but this is not a
problem.
• Do not tear off the film on the
rechargeable battery.
• Use only the supplied charging stand to
charge the supplied rechargeable
battery.
• Be sure not to short-circuit the battery.
When you carry it with you, use the
supplied carrying case. If you are not
using the case, do not carry the battery
with other metallic objects such as keys,
rings in your pocket.
•If the rechargeable battery is new or has
not been used for a long time, it may
not be charged completely until you
use it several times.
On batteries
•Do not charge a dry battery.
• Do not carry the dry or rechargeable
batteries with coins or other metallic
objects. It can generate heat if the
positive and negative terminals of the
batteries are accidentally contacted by a
metallic object.
• When you do not use the main unit for
a long time, remove the battery to
avoid any damage caused by battery
leakage and subsequent corrosion.
On AC power adaptor
• Use only the supplied AC power
adaptor (for charging stand) and
recommended AC power adaptor (for
battery case). Do not use any other AC
power adaptor.
Polarity of
the plug
• Connect the AC power adaptor to an
easily accessible AC outlet. Should you
notice an abnormality in the AC power
adaptor, disconnect it from the AC
outlet immediately.
• Do not touch the AC power adaptor
with wet hands.
On handling
• Do not leave the unit in a location near
heat sources, or in a place subject to
direct sunlight, excessive dust or sand,
moisture, rain, mechanical shock, or in
a car with its windows closed.
•We do not recommend the use of tape
longer than 90 minutes. They are very
thin and tend to be stretched easily.
This may cause malfunction of the unit
or sound deterioration.
• The LCD display may become hard to
see or slow down when using the unit
at high temperatures (above 40˚C/
104°F) or at low temperatures (below
0˚C/32°F). At room temperature, the
display will return to its normal
operating condition.
• If the unit has not been used for long,
set it in the playback mode to warm up
for a few minutes before you start using
again.
On the remote control
Use the supplied remote control only
with this unit.
On headphones/
earphones
Road safety
Do not use headphones/earphones while
driving, cycling, or operating any
motorized vehicle. It may create a traffic
hazard and is illegal in some areas. It can
also be potentially dangerous to play
your headphones/earphones at high
volume while walking, especially at
pedestrian crossings.
You should exercise extreme caution or
discontinue use in potentially hazardous
situations.
Preventing hearing
damage
Do not use headphones/earphones at
high volume. Hearing experts advise
against continuous, loud and extended
play. If you experience a ringing in your
ears, reduce volume or discontinue use.
Caring for others
Keep the volume to a moderate level.
This will allow you to hear outside
sounds and to be considerate to the
people around you.
On maintenance
•Clean the tape head and tape path,
using a cotton swab and commercially
available cleaning solvent after every 10
hours of use.
•To clean the exterior, use a soft cloth
slightly moistened in water. Do not use
alcohol, benzine or thinner.
• Clean the headphones/earphones and
remote control plugs periodically.
• Clean the battery case terminals (both
inside and outside) and the terminals
periodically with a cotton swab or soft
cloth as illustrated.
