FREQUENCY WINDOW BEHAVIOR, BASED ON
TUNING MODE SELECTIONS
If NORMAL tuning mode is selected, the 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 classes of group tuning: factory preset groups (Grp A
through D) and user programmable frequency groups (Grp U and V).
In any of the group modes, a lower case a, b, c, d, u or v will be
displayed to the immediate left of the transmitter switch settings in the
Frequency window. The letter identifies the selected factory or user
tuning group. Any time the currently tuned frequency is not in the
current group, this group identification letter will blink. Any time the
currently tuned frequency is in the current tuning group, the group
tuning mode indicator will give a steady (non-blinking) indication.
In any of the group modes, the Up and Down buttons navigate among
the selected intermod-free frequencies in the group. In factory groups
(A through D), the MENU+Up and MENU+Down shortcuts jump to the
first and last frequencies in the group. In user groups (U and V),
MENU+Up and MENU+Down permit access to frequencies not already
in the group.
