range. As the cursor scrolls across the frequency band,
Frequency Select Switch settings for the associated
transmitter are shown in the upper right corner of the
screen.
Double pressing the MENU control switches the display
to Fine View which displays an expanded portion of the
spectrum around a fixed, vertical cursor. In Fine View,
each vertical band represents one frequency (100 kHz).
As with the Coarse View, cursor movement across the
frequency band results in the displaying of the associ
ated transmitter Frequency Select Switch settings in the
upper right corner of the screen.
In Fine View, the fixed vertical center bar in the center of
the view serves as the cursor. Beneath the scan area is
a scroll bar to remind you that this is a partial picture of

lower frequencies, or clockwise to show higher frequen
cies.
Scroll through the screen and find a frequency where no
RF signals are present (or in the worst case, only very
weak RF signals). With the cursor on this frequency,
press the PREV MENU buttons to exit from scan mode.
When exiting the scan mode, you are given the option to
select either the frequency the unit was on before
entering the scan mode, or the frequency just selected in
the scan mode. The display shows "Use new freq?" to
prompt you to make a frequency selection and also
shows the new frequency. Rotate the MENU control to
select Yes. To return to the frequency you were using
before entering the scan mode, MENU control to select
NO. (The MENU button defaults to NO.) Press PREV
MENU to store the selection and exit this menu and
return to the TopMenu.
Note
Ensure the transmitter's Frequency Select Switch settings are the
same settings as shown on the display and your system will be ready
for operation.
