FM Sharing (SF2, SF4 only)
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.
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.
