Never use alcohol, paint thinner or benzine to clean this unit.
Before using chemically treated cloth, read the instructions
that came with the cloth carefully.
Caution
Do not expose the unit to direct sunlight or heat, such as from heating
appliances, as these can damage the unit.
Discontinue use if you experience discomfort with the earphones or
any other parts that directly contact your skin. Continued use may
cause rashes or other allergic reactions.
Batteries
Do not peel off the covering on batteries and do not use if the 
covering has been peeled off.
Align the poles i and j correctly when inserting the batteries.
Do not mix different types of batteries or old and new batteries.
Remove the batteries if you do not intend to use the unit for a long time.
Do not throw into fire, short-circuit, disassemble, or subject to 
excessive heat.
Do not attempt to recharge dry cell batteries.
When carrying batteries in a pocket or bag, ensure no metal objects
such as necklaces are placed together with them. Contact with metal
may cause short-circuiting which can cause a fire. For safety, carry
the rechargeable batteries in the battery carrying case.
Listening
Do not play your headphones or earphones at a high volume. Hearing
experts advise against continuous extended play.
If you experience a ringing in your ears, reduce volume or discontinue use.
Do not use while operating a motorized vehicle. It may create a traffic
hazard and is illegal in many areas.
You should use extreme caution or temporarily discontinue use in
potentially hazardous situations.
Even if your headphones or earphones are the open-air type designed
to let you hear outside sounds, don’t turn up the volume so high that
you can’t hear what’s around you.

Do not use irregularly shaped CDs.
Do not use non-specification discs.
Do not use CDs printed with label printers available on the market.
Do not use CDs with labels and stickers that are coming off or with
