Units
You can set the units for speed, depth and temperature. The units set will be used to display all data, including information received from other instruments on the system. However, the distance units do not affect the instrumented range of the display, which is always in nautical miles.
Variation Source
The variation value is the difference between True and Magnetic direction data for heading or bearing values. The Variation Source option provides soft keys for selecting Auto or Manual variation mode, displays the current variation value for each and highlights the currently selected mode.
Auto Mode
If Auto mode is selected, the value of variation is obtained automatically, normally from received data. The variation value that is used depends on the data available, and is selected in the following order of priority:
1.Variation value from the same source as the heading data:
If heading data is being taken from NMEA, then variation is also taken from NMEA.
If heading is taken from SeaTalk, then SeaTalk variation is used.
2.Variation value from a different source:
If heading data is being taken from NMEA, but no NMEA variation is available, then variation is taken from SeaTalk.
If heading is taken from SeaTalk, but no SeaTalk variation is avail- able, then variation is taken from NMEA.
3.A calculated variation value, using position data, if no SeaTalk or NMEA value is available.
