Intercom

If you have one or more Garmin Signal™ RM 100 remote stations connected to the Garmin Signal VHF 400/220 head unit through the Garmin BlueNet™ network, you can use the intercom to speak to the other stations.

See the Installation Instructions at garmin.com/manuals/SignalVHF for more information on remote stations.

Using the Intercom

  1. Select Menu icon > Intercom.

    The intercom screen appears.

    NOTE: While in intercom mode, the radio does not play VHF traffic.
  2. Hold the push-to-talk button (PTT) on the fist mic to speak to all connected remote stations.
