Tuning Setup Screen

The Tuning Setup Screen allows selection of one of four
factory set frequency groups (Groups A through D), two
user programmable frequency groups (Groups U and V)
or the choice to not use groups at all.
In the four factory set frequency groups, eight frequen-
cies per group are preselected. These frequencies are
chosen to be free of intermodulation products. (See
Frequency Coordination.)
In the two user programmable frequency groups, up to
16 frequencies can be programmed per group.

Note: The Tuning Setup Screen only selects the
tuning mode for the selected receiver module
(NORMAL or Group Tuning) and not the operating
frequency for that module. Actual operating
frequencies are chosen through the Receiver
Detail Screen. (See Adding/Deleting User Group
Frequencies.)
To set a receiver module's tuning mode, access the
Tuning Setup Screen, press the appropriate front panel
Receiver Select button, rotate the MENU/SELECT
control to select either NORMAL mode, or one of the
group tuning modes. The tuning mode will be displayed
in the Receiver Module box at the bottom of the Tun-
ing Setup Screen. If NORMAL mode is selected, then
"NOR" will be displayed in the Receiver Module box. If
a tuning group is selected, then "G A" through "G V" will
be displayed in the Receiver Module boxes, depending
on the group selected.

Returning to the Overview Screen and pressing the

selected for Receiver 1. The small "a" displayed next to
the Frequency Select Switch settings in the Receiver
Detail Screen indicates that this receiver module has
been set tuning Group A.
In NORMAL mode, only the Transmitter Frequency Se-
lect Switch settings would be displayed here.
When a receiver module is set to use a user program-
mable frequency group, the tuning behavior is modified
slightly. Turning the MENU/SELECT control navigates
among the frequencies that are "in" the currently
selected tuning group. Turning the MENU/SELECT
control while holding down the Function button allows
any frequency to be selected, whether or not it is in the
currently selected turning group.
Any time the currently tuned frequency is not in the cur-
rent tuning group, the Group Tuning Mode indicator on
the Receiver Detail Screen will blink. Any time the cur-
rently tuned frequency is in the current turning group,
the Group Tuning Mode indicator will give a steady
(non-blinking) indication.

User Programmable Frequency Group Behavior

The user programmable frequency groups work very
similar to the factory groups with a few exceptions. The
most obvious difference is the ability to add or remove
frequencies from the group. Less obvious is the behav-
ior of a user programmable frequency group with only
one, or no entries.
A user programmable frequency group with only one
entry will only display that one frequency regardless of
how much the MENU/SELECT control is turned (with-
out holding the Function button).
A user programmable frequency group with no entries
reverts to non-group-mode behavior, i.e., access is
allowed to all 256 available frequencies in the selected
receiver module's frequency block. However, once a
frequency has been added to the tuning group, this
behavior changes to group-mode behavior where the
Function button must be pressed to access frequencies
that are not part of the current tuning group.
Adding/Deleting User Programmable
Frequency Group Entries
Note: Each User Programmable Frequency Group
has separate contents for each frequency block
covered by the VRM. However, each user group's
contents are common to all receivers sharing the
same group tuning mode and frequency block.
1. Start from the Receiver Detail Screen of a receiver
module that is set to use Group "u" or Group "v" that
is also in the desired frequency range block. (See
Tuning Setup Screen.)
