Manually Tuning a NAV Frequency

NAV frequency manual tuning is performed by using
the dual NAV knob.
• The MHz (left) portion of the frequency can be tuned
by turning the large NAV knob.
• The kHz (right) portion of the frequency can be
tuned by turning the small NAV knob.
The frequency is tuned in the standby frequency field
of the NAV Frequency window. Turning either knob
clockwise increases the tuned frequency. Conversely,
turning either knob counterclockwise decreases the tuned
frequency.
