  • If the SwyxIt! is configured to play the ringtones on the C520 instead of the internal PC speaker, the volume of the ringtones can only be adjusted by the C520 itself, using the appropriate configuration dialog or during an incoming call.
  • If the SwyxIt! is muted by the SwyxIt! control during an incoming call or in idle state, the mute LED on the inline control of the C520 remains off.
    If the mute button is pressed on the inline conrol of the C520 during an incoming call or in idle state, the mute control of the SwyxIt! remains unchanged (unmuted).
    In both cases, if the call is accepted or during call establishment, the itself is muted.
  • By pressing the call button of the inline control for a longer period during an existing call, it is possible to put a call on hold or to retrieve a held call.
