Press Enter twice to select CAL VAL 1
(TRUE/MAG). The current selection is shown as
0 for magnetic, 1 for true.
3. Press Enter, the TRUE/MAG selection flashes.
4. Use the Scroll Up and Scroll Down keys to adjust
the 0/1 selection.
5. Press Enter to accept the new reference.
If on pressing Enter in step (2) the display shows anything
other than TRUE/MAG it means that there is another
heading source on the network. To eliminate the other
source, go to the COURSE function (also on the
NAVIGATE Menu) and select CAL VAL 1 (HDG NODE).
Ensure that this is set to the node number of the
Performance Unit, and then restart the instrument system.
The unwanted heading source will no longer appear in the
NAVIGATE menu.
When the heading reference is changed the text for the
HEADING function will automatically be set to show °T or
°M as appropriate. A similar change will also be made to
other functions that are heading dependent, namely
COURSE, TWD, REQD CRSE, DR CRSE and TIDE SET.
A similar procedure may be used to select the reference for
CTS (Course To Steer), which is derived from the Heading-
to-steer to destination waypoint field in the APB sentence.
As with HEADING, the text for CTS is updated
automatically when the reference is changed.
5.14.4 Handling of NMEA Alarm Conditions
Several NMEA sentences contain fields that indicate the
validity of the data. For example, GLL, RMA, RMB and
RMC contain a data valid or navigation receiver warning
flag, and GGA contains a quality indicator.
