Calibrating Audio Inputs.
Use the up or down arrow to place the cursor next to the desired audio
input calibration item ( Bal L Cal , Bal R Cal , MPX Cal , MPX SCA Cal , SCA 1 Cal or SCA 2 Cal ), then
press the accept (checkmark) button to enter the selected audio input. With the appropriate calibrated
audio source(s) applied, use the up and down arrows to set the new calibration value for the selected
audio input. When complete, press the accept (checkmark) button to save the change. Press cancel (
X
)
to discard changes and return to the previous menu.
NOTE
: Forward power (Fwd Cal), reflected power (Refld Cal), RF Drive, exciter forward (Exc Fwd) and
exciter reflected (Exc Rfld) calibrations are performed at the factory and should not require user
adjustment. Contact Nautel for assistance, if necessary.
Exciter Power
NOTE
: The exciter power setting is only available using the front panel UI.
From the front panel UI, you can set the exciter’s power level at 98 MHz. To view the Exciter Power
screen, select System Settings -> Factory Settings -> Exciter Power from the Main Menu (see
Figure ). The transmitter automatically compensates the actual exciter power level based on the
operating frequency so there should be no need to adjust this value.

Press the accept (checkmark) button to save the change. Press
