13.4 Intercom and Two-way Radio
As described in 6.5 of this user's guide, you can use
a two-way radio and SPH10H-FM Bluetooth intercom
simultaneously by using the Sena SR10, a Bluetooth
Two-way Radio Adapter, along with the SPH10H-
FM. Incoming audio from the two-way radio is not
interrupting an intercom conversation but is heard in
background. This is useful when you have an intercom
conversation with a passenger on the back seat and
use a two-way radio for group communication with
other motorcycle riders. 13.3 Intercom and GPS
If you pair a Bluetooth GPS to the SPH10H-FM as
described in 6.4 of this user's guide, you can hear
the turn-by-turn voice instruction of the GPS while
having an intercom conversation. The GPS voice
instruction interrupts intercom conversation, but it
is automatically reestablished after the GPS voice
instruction ends.
