Select each of the data monitors and verify the sensor information is correct:
NOTE
Values displayed on the Data Monitor are continuously updated by
pressing <Enter>. The sensor source is read at power-up or whenever a
configuration change has been saved. You can change the sensor source,
save it and have the data monitor reflect the change without cycling
power to the system. This will help in troubleshooting installation
problems.
a.
Change the status of the extended audio switch, landing gear, squat switch, altitude, and heading
sensors. Verify data monitors show the correct input changes (i.e., sensing of these signals).
b.
If the information is not correct, the sensor has failed to communicate with the TRC. Check
operation of the sensor and connections between the TRC and sensor.

Select Back (x <Enter>) until you return to the Service Menu.
F.3.4 Self-Test
1. Turn SKY899 OFF and then:
a.
Make sure the aircraft's transponder is in the STANDBY, ON, or ALT mode.
NOTE
After power up, it may take a couple of minutes for the altitude encoder
to return a valid altitude to the transponder and SKY899.
b.
If installed, power up the radio altimeter.
c.
Make sure all compass/HSI flags are cleared from the aircraft's instruments.
2. Turn SKY899 ON.
3. After approximately thirty seconds, observe the standby screen. Press TEST/ALT (runs self-test when
in standby or failed mode – changes vertical display modes when in operation mode).
4. If SKY899 passes the self-test, the system will return to the standby screen and the voice message,
"SKYWATCH SYSTEM TEST PASSED," will be enunciated over the cockpit audio system.
