and M (Menu).
• Pressing the I (IDT) button activates the IDENT message to be
sent by the ADS-B unit for 18 sec. IDENT is displayed while
this message is being sent. The use of this button is directed

IDENT (IDT) must be selected ON for both the transponder
and the Lynx NGT-9000R. This can be accomplished by
pushing the IDENT button on each unit or with a remote IDENT
push button which is connected to both the Lynx NGT-9000R
and the mode A/C transponder.
• Pressing the V (VFR) button sets the squawk code to a
programmed VFR code that is set in the menu (see VFR code
below). Typically it is set to 1200 (in the United States). Pressing
the button again returns the code to the previous squawk code.

functions (Info, VFR Code, and Maintenance). Rotate the large
knob to scroll the menu options across the display. Press the
small knob button to select a menu option. Press the M button to
exit to normal operation.

the CP-2500.
The VFR code can be changed from the default (always set to
1200 in the United States).
The Maintenance menu is available only when the aircraft is on
ground. Press the small knob to enter "Self TST". Press the small
knob again to see current status and rotate the small knob to
change status to enabled. Press small knob or allow the screen to
time out to set. When activated, the screen momentarily displays
"TEST STARTED". If the ADS-B Out Fail lamp is installed it
illuminates for 10 seconds during the test.
Press the small knob to exit the menu and return to normal
operation. Note: When "Done" is showing on the screen it does
not time out and the knob must be pressed to exit.
