• 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.

long time, it may not be charged completely until you use it
several times.

battery to avoid any damage caused by battery leakage and
subsequent corrosion.

place subject to direct sunlight, excessive dust or sand,
moisture, rain, mechanical shock, or in a car with its windows
closed.

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.

Use the supplied remote control only with this unit.

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.

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.

Keep the volume to a moderate level. This will allow you to hear
outside sounds and to be considerate to the people around you.

• 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
