Baseline Elevation and Azimuth Setup
After performing the assembly of the Pro Portable Terminal (complete sections 2.2 and 3.2 before starting the process
below), the user can now set the unit’s baseline elevation and azimuth. Table 3-3 provides the instructions on this
process.

1.
Once the GPS is fixed, press the
ENT
button to display the
Elevation/ Azimuth
status screen.
The
Rx LED
light will be flashing and the heartbeat tone can be
heard from the TRIA. This indicates that the TRIA is in Install
Mode and ready to begin vertically sweeping the antenna to
locate the satellite.
2.
While supporting the back of the TRIA:
Loosen the “Lock EL Angle” lever (left side of the AZ/EL
Assembly)
Loosen the “Internal Elevation” knob (beside the AZ/EL
Assembly’s “Fine Adjust Preset” label).
3.
Using the Inclinometer on the side of the TRIA manually set the
reflector elevation to the “EL” value shown on the “Status” screen
(see Step 1) and tighten the internal elevation knob.
NOTE
: If done correctly, the Inclinometer and “Fine Adjust Preset”
values should approximately match (i.e., 40° on the
Inclinometer and 40° on the “Fine Adjust Preset”).
4.
Using the “EL Fine Adjust” knob, raise or lower the TRIA angle to
dial-in the elevation reading on the Inclinometer to equal the “EL”
value shown on the “Status” screen.
NOTE
: This may take many turns to make a fine movement.
