When the unit is operating in ATC-COM mode and standby tuning is enabled the operator shall be able
to focus the standby frequency’s kilohertz field. When the kilohertz field has the focus and the
transceiver is in 25K mode, turning the Value knob clockwise shall increment the frequency by 25.0 KHz,
while turning the knob counterclockwise shall decrement the frequency by 25.0 KHz. When the kilohertz
field has the focus and the transceiver is in 8.3K mode, turning the Value knob clockwise shall increment
the frequency by 8.33 KHz, while turning the knob counterclockwise shall decrement the frequency by
8.33 KHz. Note that the displayed frequency and actual frequency are not the same when in 8.3K mode.
Refer to Appendix B for more information. Figure 34 depicts the standby frequency being tuned by KHz.
Figure 34 Changing Standby Frequency by KHz
When the unit is operating in ATC-COM mode and standby tuning is enabled and the operator presses
the FREQ Transceiver-Menu button, the Frequency-Entry dialog shall appear to change the standby
frequency on the active transceiver. Figure 93 depicts the channel frequency selection dialog.
If the frequency entered is valid, it shall be loaded into the active transceiver and the display shall return
to the Normal-Operation-Page. If the entered frequency is invalid, the digits entered shall be cleared
and the operator can try again. Pressing the HOME button shall cancel the operation and return to the
Normal-Operation-Page.
6.4.1.7.2 ATC Mode
When the unit is operating in ATC-COM mode and the operator presses the ATC Transceiver-Menu
button, the transceiver shall change to Tactical mode.

YSTEM FUNCTIONS
The following sections describe system functionality, i.e. functionality that is not transceiver specific.
This includes system configuration, brightness control, and advanced modes of operation, such as relat
or simulcast.
6.4.2.1 Brightness Control
When the operator turns the brightness knob, the Brightness-Control dialog shall appear. This dialog
shall allow the operator to adjust the display brightness level from 0% to 100%. These levels shall be
user configurable via lighting curves. The Brightness-Control dialog is depicted in Figure 35.
