Muting a Call
If you’d like to say something without the receiving party
hearing you, you can press the MUTE button. When you mute
a call, the ONLINE light will blink.
To turn off the mute feature, press MUTE again. (The
ONLINE light will stop blinking and remain illuminated for the
remainder of the call.)
