4.3.5 POSITION
This is to select a positioning data either by MANUAL or AUTO. Sentences to receive
are IEC61162-1 (equal to NMEA Ver.3): GGA > RMC > GNS > GLL and ZDA. When
manual input position, it changes to GPS data automatically when inputted the position
data from GPS and so on. Then, when using GPS data, manual input is not available.
The related setting is [MENU] -> POSITION OLDER.
Procedure
1. Select [MENU] -> POSITION and press [ENT] key.
2. Select INPUT TYPE, either AUTO or MANUAL, and press [ENT] key.
If a positioning data is inputted, select AUTO. When MANUAL is set up, input your
own ship’s position and positioning time.
How to operate IEC61162-1
1. UTC shown on VHF display is an indication of ZDA time. When there is no ZDA
available, time available in GGA > RMC > GNS > GLL will be used.
2. ZDA is used to indicate Date/Time on a printed-out self-test result. When ZDA is
not available, time available in a GGA > RMC > GNS > GLL, and date available
in a ZDA > RMC will be used.
3. Matching talker: GP > LC > DE > II > IN > EC > TR > LA > OM
4. Data can be received regardless of the availability of expansion field.
