HTC ISW13HT Basic Manual page 37

Be sure to read the following
cautions before use.
Adjust the volume to the proper level.
Setting too loud a volume or using the
Instruction
earphones continuously for a long period
of time might adversely affect your
ears. Also, raising the volume too high
might prevent you from hearing sounds
around you, which might in turn lead to a
traffic accident at a railroad crossing or
pedestrian crossing.
When adjusting the volume, raise the
volume a little at a time. If you raise the
Instruction
volume too much from the outset, sudden
loud noise from the earphones might
adversely affect your ears.
If you feel any abnormality with your skin,
immediately consult a dermatologist.
Instruction
Itching, rashes, eczema, etc. sometimes
occur depending on your physical
constitution and condition.
