When you are a member of an active three-way
conference intercom, you can completely terminate
the conference intercom or just disconnect an
intercom connection with one of your active intercom
friends.
1. Press the Jog Dial for 1 second until you hear
a beep to terminate three-way conference
intercom completely. It terminates both intercom
connections with (B) and (C).
2. Tap or double tap the Jog Dial to disconnect
intercom connection with one of the two intercom
friends accordingly. For example, by single tapping
the Jog Dial, you can just terminate the intercom
connection with the first intercom friend (B).
However, you still have the intercom connection
with your second intercom friend (C).
