The azimuth field shows a current position value of the azimuth axis. It also shows the status of azimuth

The value displayed may be changed by the Scroll Up/Angle CT key. The display will rotate between
showing antenna angle, antenna pulse count, magnetic heading and true heading values. When first
entering MANUAL mode, the field will always be initialized in the display mode selected by the
initial_azimuth_display configuration item (3.3.1.2.3).
The magnetic and true heading values are derived by taking the current heading estimate of the mount
(see the LOCATE function) and adding the antenna angle. If there is currently no mount heading
estimate, the field will display "-------". If the current heading estimate has not been "fixed" (either
manually or automatically by the DVB receiver function), the field will be annunciated by small letters
(mag: or true:) to indicate that the heading value may be inaccurate due to compass error. If the
RC3000's heading estimate has been "fixed", the field will be annunciated in capital letters (MAG: or
TRUE:) to indicate confidence that the value represents an accurate magnetic or true heading.

Following a LOCATE operation, the azimuth and elevation limit fields will display the target angles in
parenthesis. If a limit condition is active, the limit display will overwrite the target values.

POL:
This field shows the current angular value of the polarization axis along with its limits (CCW, CW). This
field will also show if the polarization axis has been placed at a predefined horizontal (H) or vertical (V)
position. An asterisk (*) placed before the POL label indicates that the proceeding LOCATE function
calculated that a waveguide switch “flip” will have to occur.

The value of the predefined horizontal and vertical positions depends on what mode was active prior to
entering the MANUAL mode. If a LOCATE operation occurred prior to MANUAL, the H and V values will
be those automatically calculated by the LOCATE mode. Otherwise H and V depend on whether or not
satellites have been STOREd. If MANUAL was entered following a RECALL operation, H and V will be
those stored for the RECALLed satellite. If multiple satellites have been STOREd, H and V will
correspond to the values for the closest (in terms of azimuth location) STOREd satellite. If no satellites
have been STOREd, H and V will be that of the default horizontal and vertical positions set by the user.
