15.2  End Four-way Intercom
As same in the case of three-way intercom, you 
can completely get out of the four-way conference 
intercom or just disconnect a single intercom 
connection.
1.  Press the Jog Dial for 1 second until you hear a 
beep to terminate four-way conference intercom. It 
terminates the intercom connections between you 
(A), and your intercom friends (B), (C) and (D).
2. Tap or double tap the Jog Dial to disconnect 
the intercom connection with one of the two 
intercom friends accordingly. However, when 
you disconnect the second friend (C) by double 
tapping the Jog Dial, you will be disconnected with 
the third participant (D) as well. This is because 
the third participant (D) is connected with you via 
the second friend (C).

16. THREE-WAY CONFERENCE 
PHONE CALL WITH INTERCOM 
PARTICIPANT
You can have a three-way conference phone call 
by adding an intercom friend to the mobile phone 
conversation. While having a mobile phone call, make 
an intercom call to one of the intercom friends by 
tapping the Jog Dial to form a three-way conference call 
with the person on the mobile phone line. To disconnect 
the intercom first and go back to your private mobile 
phone call, terminate the intercom by tapping the Jog 
Dial. To end the mobile phone call first and maintain 
the intercom conversation, press the Jog Dial for 2 
seconds, or tap the phone button, or wait for the person 
on the mobile phone line to end the call.
