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.
Note: User Group Tuning available in units with 
firmware version 3.0 and above.
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 (NORMAL or Group Tuning) and 
not the operating frequency. Actual operating 
frequencies are chosen through the Frequency 
Window.
Frequency Window Behavior
If NORMAL tuning mode is selected, the SEL Up and 
Down buttons select the operating frequency in single 
channel (100 kHz) increments and the MENU+Up and 
MENU+Down shortcuts tune in 16 channel (1.6 MHz) 
increments.
There are two types of group tuning modes: factory pre-
set groups (Grp A through D) and user programmable 
frequency groups (Grp U and V).
When using Group Tuning, a lower case “a, b, c, d, u” or 
“v” will be displayed to the immediate left of the trans-
mitter switch settings in the Frequency Window, indicat-
ing which group is selected. If currently tuned frequency 
is not in the current tuning group, the indicator will blink.
If a factory tuning group has been selected, pressing 
either the SEL Up or Down button will select the nearest 
factory selected frequency in that group above or below 
the current frequency.
User Programmable Frequency Group Behavior
The user programmable frequency groups work very 
similarly 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 
behavior 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 many times the SEL Up or Down buttons are 
pressed (providing the MENU button is not pressed at 
the same time).
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 
MENU button must be pressed and held while either 
the SEL Up or Down buttons are 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 
(“u” or “v”) has separate contents. It is suggested 
to review the section titled Frequency Coordination 
prior to adding frequencies in order to minimize 
potential intermodulation problems.
1.  Start from the Frequency Window and verify 
that a lower case “u” or “v” is present next to 
the transmitter switch settings.
2.  While pressing and holding the MENU button 
press either the SEL Up or Down button to 
move to one of the 256 available frequencies 
in the block. Whenever the selection comes 
to rest on a frequency that is in the current 
group, the group tuning mode indicator (letter 
“u” or “v”) will give a steady indication. On 
frequencies that are not in the group, the 
indicator will blink.
3.  To add or remove the displayed frequency 
from the group, hold down the MENU button 
while pressing and holding the SEL Up button 
for about a second. The group tuning mode 
indicator will stop blinking to show that the 
frequency has been added to the group, or 
begin blinking to indicate that the frequency 
has been removed from the group.
