Changing a Channel Name

Channel names appear on the home screen using nine characters. If a channel name is longer than nine
characters, the full name scrolls across the top of the screen, then switches to the short name. You can change
the name of a channel to reflect a local meaning.
1 Select MENU > CHANNEL > NAME.
2 Turn the ENTER dial to select a channel, and select OK.
3 Change the name of the channel
4 Select ACCEPT.

Restoring Factory Settings

You can restore the radio to the default factory settings. When you restore the radio to factory settings, all
system changes and customizations are lost. Restoring factory settings deletes the call logs, but retains group
entries, directory entries, the MMSI number, and the ATIS ID.
1 Select MENU > SYSTEM > SYSTEM INFO > RESET.
2 Select YES to confirm the reset.

Channel Prefixes

In January of 2017, new international regulations changed the numbering scheme for maritime VHF channels.
Channels which were previously numbered with a suffix of A or B now have a prefix of 10 or 20.
• Channels formerly noted with an A now have a prefix of 10. These channels transmit and receive using only
the ship station frequency and can be used for direct ship-to-ship communication.
• Channels formerly noted with a B now have a prefix of 20. These channels transmit and receive using only
the shore station frequency.
