Phoenix Quattro User Manual page 13

Note: when working with both a VoIP application and an additional communication interface,
it is recommended that you set the speakers level using your computer's volume controls
first. Then you can use the unit's volume controls to set the output level of both interfaces to a
comfortable level. The reason is that your computer controls only the level of signal coming
out of your computer and not of the other interface while the unit's volume controls affect
both.
4) Push the power button with a short push to toggle between Microphone On and Mute.
When muted – the light will blink.
5) Push and hold for 4 seconds to turn the unit off (the unit will beep four times and turn off
on the fifth).
