USB Headset Adaptor

INSTALLATION GU IDE & USE R MANUA L.

Thank you for purchasing an Accutone USB kit, this kit includes an
AU300 USB Headset Adaptor and a CM300 stereo headset. The AU300
adaptor connects any computer headset to your computer via digital
connection, which provides a purer and better sound quality of audio
signals. Unlike any traditional connection through analog sound cards,
which may cause distortion to the sound signal as it's being processed
and converted from analog to digital, the AU300 adaptor provides far
superior sound quality, which is perfect for performance-sensitive
applications such as VoIP chat or voice recognition software...etc.

Now please spend a few moments to read through this user manual
before connecting the USB headset kit to your computer. After
familiarizing with the features and functions, you will surely appreciate
the top audio performance this unique device has to offer you.
