15. FOUR-WAY CONFERENCE
INTERCOM
15.1 Start Four-way Intercom
You can have four-way conference intercom with three
other SPH10 users by adding one more intercom
participant to the three-way intercom. While you are
having three-way intercom as above in section 14.1, a
new participant (D), who is an intercom friend of your
intercom friend (C), may join the conference intercom
by making an intercom call to your intercom friend
(C). Please note that in this case, the new participant
(D) is an intercom friend of (C), not of you (A).

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).

with your second intercom friend (C).
