■
IS12S Main unit
Be sure to read the following cautions before
use.
When playing games, music or watching TV (1Seg), adjust the volume to
the proper level. Setting too loud a volume or using the earphone
continuously for a long period of time might adversely affect your ears.
Even when the volume is adjusted moderately, using the earphone for a
long period of time might cause a hearing loss. 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.
Do not wrap the cord around IS12S to use. Sensitivity might drop, causing audio
to be interrupted or noise to be heard. Do not pull the cord to remove. Do not hang
the product by holding the cord. Doing so might cause damage the terminal.
Prevent dust from adhering to terminal. Failure to do so might cause a
fault.
Insert/remove the connector straight to/from the terminal of IS12S.
When adjusting the volume with the Stereo Headset with Microphone
(Sample) inserted into the product, raise the volume a little at a time. If
you raise the volume too much from the outset, sudden loud noise
from the earphone, etc. might adversely affect your ears.
For detailed operations on the initial setup, refer to the instruction
manual for the Stereo Headset with Microphone (Sample).
If you feel any abnormality with your skin, immediately consult a
dermatologist. Itching, rashes, eczema, etc. sometimes occurs
depending on your physical constitution and condition.
