Com and Nav Frequency Window and Tuning
Communication frequencies are selected by using the
large
and
small right
knobs or by touching the value in the
standby
Com or Nav frequency field and
using the displayed keypad. The standby frequency always appears below the
active frequency. The active frequency is the frequency currently in use for
transmit and receive operations.
Once a frequency is selected in the standby field, it may be transferred to the
active frequency by touching the active frequency field.
NOTE:
The Com window is normally active for adjustment, unless the NAV
window is made active by pressing the
small right
knob. The active state
automatically returns to the Com window after 30 seconds of inactivity.
To select a Com or Nav frequency using the small and large right knobs:
1. If the tuning cursor is not currently in the frequency window,
press the
small right
frequency will be highlighted to indicate that it is active for
editing.
2. Turn the
large right
knob to select the desired megahertz
(MHz) value. For example, the “118” portion of the frequency
“118.30.”
3. Turn the
small right
knob to select the desired kilohertz
(kHz) value. For example, the “.30” portion of the frequency
“118.30.”
To select a Com or Nav frequency using the numeric keypad:
1. Touch the Standby window.
2. A keypad will appear with the current Standby frequency
highlighted.
