Speaker devices
The VHF radio can be equipped with the following speaker devices:
• SAILOR 6201/SAILOR 6203 Handset with cradle and PTT (Push To Talk)
button.
• SAILOR 6202 Hand Microphone with PTT button.
• SAILOR 6204 Control Speaker Microphone with PTT button.
See Controller setup on page 44 for controlling the connected speaker

DSC and MMSI number
The MMSI is a unique, 9-digit identifier assigned to your ship. When the
VHF radio is powered on for the first time, the vessel’s MMSI number is
programmed in the radio. This is typically done during installation of the
radio and described in the installation manual.
Important
The MMSI number must be programmed into the VHF radio
to use any DSC functionality. The radio will prompt for the
MMSI number at each power-up until the MMSI has been
entered. You can use the radio in normal VHF mode.
Caution! Without a programmed MMSI number the
Distress button will not work!
