Special Notes (continued)
Avoiding hearing damage
If volume on the earphones is too high, permanent hearing loss may occur. Please
set the volume to a safe level. You can become habitual to hear at high volume that
may sound normal but can damage your ears. If you experience ringing in your
ears or mufed speech, stop listening and have your ears checked by the specialist
doctor. The louder the volume, the more quickly the hearing can be damaged.
Hearing experts suggest how to protect your hearing
●Limit the amount of time you use the earphones at high volume.
●Avoid the habit of increasing the volume so that you do not hear the loud noises
around you.
●Turn the volume down if you cannot hear people speaking around you.
For setting the maximum volume limit of the connection device,
refer to the instruction manual supplied with the connection device.
Class B equipment (home-use broadcasting communication equipment):
This equipment is intended for home-use (Class B) electromagnetic compatibility
equipment and can be used in all areas.

can cause hearing loss. Adjust the volume to an appropriate level when using the
earbuds.
