4. In normal operation the user can change the operational mode,
set the squawk code, view the current pressure altitude, and
optionally set a flight ID mode. (The flight ID function is optional
and is part of the configuration options set during installation of
the Lynx NGT-9000R.) Select these items by rotating the large
knob.
The operational mode is changed by rotating the small knob
and can be set to Altitude, On, or Standby. The Altitude (ALT)
mode should always be selected unless Air Traffic Control (ATC)
requests a change or if there is a known problem with the control
panel or Lynx NGT-9000R.

ADS-B Out Fail lamp is ON and the ADS-B System Fail message
is displayed on the CP-2500 screen.

the squawk code is to first change the Transponder and
then confirm on the CP-2500 per the "PUSH TO ACCEPT"
explanation found in step 6 below.
