If you are using the CHAT 160 with an application other than CHAT−such as Cisco Communicator or
Skype−ClearOne recommends using the tuning wizard or audio configuration controls in that application to
adjust audio settings. If the application does not have a tuning wizard or audio settings, use the CHAT
application to tune audio settings for optimal sound quality as explained in the next section.
