Description
This group of entry keys lets you manipulate numerical values in the
active entry line.
@
and
a
arrow keys identify (by underlining) the digit to be
changed. For example, if CW frequency is in the active entry line,
and the display indicates:
-->
cw:
10005.000000 MHz
you may wish to change the 5 to a 6. Press the
a
five times until
the underline is under the 5. Now use the rotary knob or the
m
to change the 5 to a 6. The underlined digit remains the active
character in this function until the synthesizer is preset, turned off, or
the underline is moved completely left or right.
The
a
and
Q)
arrow keys increment or decrement the numeric
value by a predetermined amount. The increment value depends
on the active function and the step value set. All increment values
are defaulted to their original values when the synthesizer is preset
(unless Preset Mode User has defined the default differently).
