1. Navigate to the Tuning setup screen.
2. Select each module in turn with the Receiver Select
Buttons and select the desired tuning group. Then
return to the overview screen.
3. Turn transmitters off. From the overview screen,
open the receiver detail screen for each module
and rotate the MENU/SELECT control to select a
frequency where no RF signal is indicated.
Finding Clear Channels
Using Full Spectrum Scan
In crowded RF environments, it may not be possible to
find enough clear channels using a Tuning Group. The
internal spectrum scanner can then be used to find
clear channels manually across the entire tuning range
of the receiver in 100 kHz steps.
1. Turn off all transmitters and set all receiver modules
to the NORMAL tuning mode (not a tuning group).
2. Select Scan from the TopMenu and press the
MENU/SELECT control.
Select the receiver module to use for scanning and
press MENU/SELECT. The scanning begins auto-
matically.
3. Allow the scanner to continue sweeping through the
tuning range several times, then press the Function
button to enter “Stop Mode.”

spectrum. Press the Function Button to ZOOM to a

5. Press the BACK button to return to the “Stop Mode.”
NOTE: At any point in the Stop or Zoom screens,
you can select any module on the same block to
tune.
6. Press the BACK button to return the previous menu
to select the next receiver to use for scanning.
7 . Continue from step 2 to scan all blocks that are
installed.
8. Conduct a system checkout with the procedure
explained in the section entitled Diagnostics.
Adjusting Audio Output Levels
The audio output levels at the rear panel XLR jacks are
software controlled. (The front panel LEVEL knob af-
fects the PHONES output only.)
The optimum output level will provide the highest level
signal possible without overloading the input to external
equipment or driving a subsequent stage in the signal
chain into limiting or compression. Ideally, the gain
needed to drive the rest of the signal chain should be
present at the receiver outputs, with each successive
stage in other equipment set to unity (no gain or loss).
NOTE: In Ratio Diversity and Frequency Diversity
modes, the receiver modules are paired 1-2, 3-4,
5-6. Setting the audio level output on either module
in the pair, sets the audio output to the same level
on both of them.
1. Navigate to the Level setup screen.
