15.1 Start Four-way Intercom
You can have four-way conference intercom with three other SMH10 
users by adding one more intercom participant to the three-way 
intercom.	 While	 you	 are	 having	 three-way	 intercom	 as	 specified	 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).

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).
