Fine-tuning Azimuth and Elevation Setup
After performing the assembly of the Pro Portable Terminal (complete sections 2.2, 3.2, and 3.3 before starting the
process below), the user can now fine-tune the unit’s azimuth and elevation. Table 3-4 provides the instructions on
this process.

1.
Loosen the “Lock AZ Angle” knob (left highlight) and the “Lock AZ
Angle” knob (right highlight) on the bottom of the base plate.
NOTE
: Leave the “Lock AZ Angle” knob just tight enough to allow
the azimuth to move.
2.
Using the “AZ Fine Adjust” knob, horizontally adjust the azimuth:
a.
Left until the tone changes from a “Low/Slow” tone to
NO
tone.
b.
Maintaining a consistent speed, start turning the adjustment
knob right while counting until you hear the tone go from:
No Tone → Low/Slow → High/Fast → Low/Slow → No
Tone
c.
Divide the ending count number by 2 and using the same
speed, turn the knob right until you reach the halfway mark.
No Tone → Low/Slow → High/Fast
NOTE
: The modem screen’s “SNR” and “Peak” dB numbers will
change during this process, and the screen will report a
“Status” as “Complete” even though the fine-tuning process in
not complete.
3.
Tighten the two “Lock AZ Angle” knobs on the base plate so the
antenna has no movement left or right.
NOTE
: If you lose the tone while tightening; loosen them and
repeat the above steps.
