RADIO TUNING AND DISPLAY
The KSN 770 displays the standby and active frequencies of the
selected internal radio in the lower--left corner of the display, shown in
Figure 5--7. The active frequency is displayed in green with a gray
background and the standby frequency is displayed in green with a blue
background.
Figure 5--7
Standby and Active Frequencies
The standby/active frequencies are swapped by pushing
the frequency swap bezel key next to the radio tuning
window.
Rotating the outer knob of the radio control knob
tunes the selected radio standby megahertz (MHz)
frequency (the digits to the left of the decimal point).
Rotating the inner knob tunes the selected radio
standby kilohertz (kHz) frequency (the digits to the
right of the decimal point).
When a frequency is tuned using the radio control knob, the standby
frequency is displayed in magenta with a gray background, as shown
in Figure 5--8, for 5 seconds. Within 5 seconds or when the frequency
is made active (whichever occurs first), the standby frequency is
displayed in green with a blue background.

Tuned Standby Frequency
When a COM or NAV frequency is tuned from the touchscreen
(described later in this section), the standby frequency is displayed in
white with a magenta background and fades away within 3 seconds to
the normal display.
