If this feature is enabled, you can initiate an intercom 
conversation with the last connected intercom friend 
by speaking any word loudly enough.The most 
effortless way to trigger intercom VOX is to blow into 
the microphone as if blowing dust off the microphone. 
If you start an intercom conversation by VOX, the 
intercom terminates automatically when you and your 
intercom friend remain silent for 20 seconds. However, 
if you manually start an intercom conversation by 
tapping the Jog Dial, you have to terminate the intercom 
conversation manually. 
However, even when this feature is enabled, if you 
terminate intercom conversation manually with the 
Jog Dial, you are not able to start intercom by voice 
temporarily. In this case, you have to tap the Jog Dial 
to restart the intercom. This is to prevent repeated 
unintentional intercom connections by strong wind 
noise. If you tap the Jog Dial to start an intercom 
conversation, it is not terminated by 20 seconds of 
silence. After turning SPH10H-FM off and on, you can 
start intercom by voice again.

RDS AF allows a receiver to re-tune to a different frequency 
providing the same station has an additional frequency. In 
RDS AF, the receiver will “re-tune” to the second frequency 
location	 when	 the	 first	 signal	 becomes	 too	 weak.	 With	
RDS AF enabled on the receiver, a radio station with more 
than one frequency can be used.
