direct control of your Skype software from your headset!
Thank you for purchasing the Accutone® USB500 VoIP Communication Headset.
This high-performance headset is designed for professional Voice over IP
communication, whether it is Skype® chat or any proprietary softwares. Although
the USB500 is tailor-made for human voice applications, its 40mm customdesigned stereo speakers are more than capable of handling top notch hi-fi gaming
as well as listening to music with your PC. Aside from perfect sound reception, it is
also equipped with Accutone®'s noise cancelling microphone. On top of all that, we
have reduced the size of the USB module, added the control interface while still
fitting it into a compact and stylish casing, giving you digital audio control without
compromising convenience.
Now please spend a few moments to read through this user manual before
connecting the USB headset 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.

B4. under different operating system
The USB500’s interactive control function is designed to pair with Microsoft® Windows
OS* only. The software CD that accompanies this manual includes a direct installer that
runs automatically under Windows. Aside from the USB device drivers, the CD will also
install a Skype-controlling application called a “Middleware”. The middleware program
is only designed to work under Windows OS.
Under other OS like Apple** or Linux, the headset as well as the in-line control will still
be operative, without the need to install a USB device driver. Users should still be able
to control volume, speaker mute and microphone mute from the in-line control.
However, because the Middleware cannot operate properly under Mac or Linux OS,
the extra Skype-controlling feature will not function at all.
* Microsoft Windows OS refers to Windows 98 SE, Windows ME and all derivative versions of Windows 2000 &
Windows XP.
** USB device driver not required for Mac OS 9 and above. For Linux driver requirements, please visit their
respective websites.

C3. setup sound devices in the Skype program
By default, the Skype program will use Windows Default Device as it’s audio input and
output channel. This can either mean it is using your default Sound Card, or whichever
audio device you’ve setup in Sound Devices inside the Control Panel.
We will need to change the device to the Accutone USB
headset. First, make sure you have the USB500 headset
plugged in, and the driver properly installed as shown in
the previous sections.
Open the Skype program, under Tools menu, select
Options, and the following screen will open up.
Click Install to continue installation.
After a few minutes of copying files,
this screen will pop up indication the
successful completion of Accusound.
Click Finish to exit installer.
Select Sound Devices in the left panels. On the right panel, open up the Audio In dropdown menu and you should see Accutone USB Sound Device, select it. Do the same for
the Audio Out selection.
Note: In some cases, the driver may read USB Audio Device, select it anyways. However you should uncheck
the Let Skype Adjust My Sound Device Settings, as the Windows default driver may cause microphone cut-off
during Skype talk. (Do not worry about this if you are using the Accutone USB driver.)
