• The TAWS option default setting is "Enable". Press the small knob to change the setting to
"Inhibit". Selecting inhibit removes the TAWS alert message from appearing on the CP-2500
display and stops all TAWS aural alerts from occurring. The message "TAWS INH" is shown
on the display while the TAWS option is inhibited.
• The TAWS Obstacle option default setting is "Enable". Press the small knob to change the
setting to "Inhibit". Selecting inhibit removes the TAWS terrain alert message from appearing
on the CP-2500 display and stops the audio 500ft altitude call-out caused by obstacles. The
message "OBST INH" is shown on the display while the obstacle option is inhibited.
5. The CP-2500 has three buttons identified as I (Ident), V (VFR), and M (Menu).
• Pressing the "I" button activates the IDENT message to be sent by the ADS-B unit for 18 sec.
IDENT is momentarily displayed while this message is being sent. The use of this button is
directed by Air Traffic Control (ATC).
• Pressing the "V" button sets the squawk code to a programmed VFR code that is set in the
menu. Pressing the button again returns the code to the previous squawk code.
• Pressing the "M" button gains access to the menu, as well as the firmware and hardware status.
Rotating the large knob allows the pilot to access different modes. The Menu button also allows
access to the Maintenance Mode, where the pilot can conduct a self-test. Press the M button to
exit to normal operation. (Alternately rotate the large knob to scroll the screen to “Done and
then press the knob to return to the normal operation screen.)
o Self-Test operation:
a. Rotate the large knob to scroll the menu to Maintenance
b. Press the small knob to enter “Self TST”.
c. Press small knob again to activate self-test. When activated, the screen momentarily
displays “TEST STARTED” followed by “TEST IN PROGRESS”, each lasting for 5
seconds.
• "TEST PASS". Unit returns to previous operation.
• "TEST FAIL". After this message is seen, additional messages are shown for
each test that failed. Possible messages: "NO LRU RESPONSE", "XPDR FAIL",
"ADS-B OUT FAIL", "ADS-B IN FAIL", "FIS-B FAIL", "GPS FAIL", "TAS
FAIL", TCAS FAIL, "TAWS FAIL".
• If a degraded condition is detected a degraded message is flashed on the CP-2500
screen. The possible degraded messages are "ADS-B OUT DEGRADED",
"ADS-B IN DEGRADED", "TAS DEGRADED", TCAS DEGRADED, "GPS
INIT", "CONFIG MODULE - SERVICE SOON".
• If the optional ADS-B Out Fail lamp is installed it will be illuminated for 10
seconds during the test.
d. While the test is in progress observe that 3 targets are shown on the PED or traffic
display (if installed) used by the Lynx MSS. If installed the ADS-B Out Fail lamp
(located on instrument panel) will flash for a couple of seconds.
• One traffic should be at a -90 degree bearing, -200 feet relative altitude and have
a climb vertical sense. Another traffic should be a -34 degree bearing, +1,000 feet
relative altitude with a level vertical sense. The last traffic should be a +34
degree bearing, -1,000 feet relative altitude with a descending vertical sense.
• If no targets are seen or the lamp does not flash, then troubleshoot the
installation, including the Lynx MSS and associated systems to determine cause.
