ible IFB receiver.

TUNING Setup Screen
The TUNING setup screen allows
selection of one of four factory set
frequency groups (Groups A through D), two user pro-
grammable 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. (Refer to
receiver manual for more information).
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.
