Pressing and holding the CLR key for 3 seconds during either ENTRY or

Adding Ship Stations to the List
Adding to the phonebook list for ship stations is made in the order: MMSI

registration.
2) To enter the MMSI number, press the corresponding numeric keys (0
through 9). The currently selected location is indicated by a flashing
"–" character. Pressing a numeric key enters that value then advances
to the next digit's place. To go back by 1 digit, press the CLR key.
3) To enter the nickname, use the numeric keys (0 through 9) to input the
associated alpha or numeric value (refer to section 3.2 Controls and
LCD Display). The currently selected location is indicated by the
flashing "–" character. After inputting the desired letter or numeral,
press the ENT key to submit the entry and proceed to the next place.
To go back by 1 digit, press the CLR key.
If no nickname is to be registered, press the ENT key for all characters
so that they all display a "–".
Note:
The 0 key will enter only the numeral "0", while the 1 key will alternately
enter "1" and "space". The 0 and 1 keys do not have associated alpha
characters.
