Temporary Preset; Fm Sharing; Region Selection - Sena SF4 User Manual

12.5 Temporary Preset

With the temporary preset function, you may temporarily preset
stations automatically without changing the existing preset stations.
Tap the (+) Button three times to automatically scan for 10 temporary
preset stations. The temporary preset stations will be cleared when
the system is powered off.
12.6 FM Sharing(SF2, SF4)
With FM sharing, you can listen to the radio during the intercom
conversation. To start FM sharing, press the (-) Button for 1 second
during the intercom conversation. During FM sharing, you can move to
the next preset station and you or your friend on the intercom can
change frequencies. If either person changes the frequency, the other
will listen to the same frequency. To terminate FM sharing, press the (-)
Button for 1 second or end the intercom call.
Note:
1. FM sharing will be terminated if the SF4 starts a multi-way intercom
conference.
2. When Audio Overlay is enabled, if an intercom call is made while you are
listening to the FM radio, FM sharing will not work.

12.7 Region Selection

You can select the proper FM frequency region from the Sena Device
Manager. With the region setting, you may optimize the seek function
to avoid unnecessary frequency ranges (factory default: worldwide).
