English
b. To reject the phone call and stay on the intercom
conversation, press the Jog Dial for 2 seconds
until you hear a beep.
Unlike other motorcycle Bluetooth headsets, this
prevents a user from being dropped out of an
intercom conversation by an incoming mobile call.
2. When you have an incoming intercom call during a
mobile phone call, you will hear 4 high tone beeps,
alerting you that there is an incoming intercom call.
You will also hear a voice prompt saying “Intercom
requested”. In this case, the intercom call does
not override the mobile phone call because
intercom has lower priority than mobile call. You
have to hang up the mobile phone call to make or
receive an intercom call.
13.3 Intercom and GPS
If you pair a Bluetooth GPS to the SPH10 as
described in 6.3 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.

13.4 Intercom and Two-way Radio
As described in 6.4 of this user's guide, you can
use a two-way radio and SPH10 Bluetooth intercom
simultaneously by using the Sena SR10, a Bluetooth
Two-way Radio Adapter, along with the SPH10.
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.
