The current lat/lon that the gps has calculated is displayed. The UTC the gps is outputting is also
displayed to show that the data is being updated. To select this lat/lon, press the Enter key. Note that if
the gps is not reporting a valid position fix, the message "WAITING FOR GPS" will appear.

3.2.2.7.2 HEADING

When the user chooses to modify heading, a screen appears showing the current heading (HDG:) and
source (SRC:) of heading. If valid heading data is coming from the fluxgate, this data will appear in the
FLUX HDG: field. The MAG VAR: field displays the calculated magnetic variation for the current
lat/lon/date. If the RC4000 thinks it needs to recalculate magnetic variation (thinks lat/lon has changed)
the MAG VAR: field will flash "CALC". The magnetic variation calculation may take up to 10 seconds.

To modify the heading to the value determined via the fluxgate (flux heading + azimuth offset +mag var)
press the 3 key.
If the user wishes to enter a magnetic heading of the vehicle, press 1.

After the magnetic heading is entered, the RC4000 will apply the magnetic variation and azimuth offset to
generate the true heading of the mount's azimuth centerline.
If the user wishes to manually enter true heading, press the 1 key and the prompt to enter heading will
appear on line 3 as shown below.
