First startup conguration
The first time the radio is powered up, the user is prompted to make
a series of setting selections in order to allow the radio to perform
to its full potential. Some steps must be completed; some are
optional and can be completed later. The steps are outlined below
for reference:
Select the region and country the radio will be operated in.
Enter MMSI number if known, or skip to next step. Re-enter number
to confirm correct entry.
¼ Note: MMSI entry can only be done once. Changing the MMSI
requires radio be returned to a Simrad dealer.
