The figure above illustrates the MMSI number entry of 992344513.
If a valid MMSI is already stored in the radio's memory, you will not be
able to enter a MMSI number. If a 9-digit MMSI number has not been
programmed into the radio, you will not be able to make or receive DSC
calls. To enter your assigned MMSI number, follow the steps listed in
the MMSI Setup below.
Warning
Again, there is only one chance to do this procedure cor-
rectly, so go over this section carefully.
MMSI Setup
1. Hold down the
CALL key for 5 seconds. The ID ANNUNCIATOR will blink
and a large
"0" will be displayed alongside a small “16.” The big number
“0” is the MMSI digit you are entering and the small digit “16” is the
first MMSI character field position. For example, a small digit
"2" rep-
resents the 2nd number from the left in your assigned MMSI. If the
number was
"4" it would mean the big digit you were entering was the
4th number from the left and so on.
This example gives us a closer look at a number sequence from a MMSI
entry. The big numbers are the MMSI digits. The small numbers in the
lower right hand corner represent the digits' character field position.
The big digit 4 is the sixth number from left in the MMSI. The big digit
5 is seventh from left and the big digit 1 is eighth from left.
