3.5.4 Self Test
A self-test feature tests the (aural) alarm, attempts self calibration, and activates each display element in a
pre-determined sequential pattern to allow visual verification that display outputs issued by the digital
processor can be correctly interpreted by the pilot.
Self tests may be performed indoors but signal multi-path from building walls may be a
factor. If problems are experienced, self tests should be performed outside away from
buildings, and where local traffic is not a factor.
With the GTS 8XX powered up and Standby indicated on the CDTI, cycle the GTS 8XX to Self Test. The
self test feature of the GTS 8XX tests the following internal parameters as well as performs calibration of
various components in the GTS 8XX:
a) Calibration data fault – Stored factory calibration parameters are invalid. Return unit to Garmin
for service.
b) Configuration data fault – Stored system configuration parameters are invalid or Mode S address
is invalid (All 0's or F's ). Fault will persist until configuration is corrected. Attempt
configuration per the Configuration Section.
c) FPGA fault – Check of the FPGA image failed. Fault will persist until valid FPGA image is
loaded. If upload of FPGA image was recently attempted, retry the upload. Otherwise, return
unit to Garmin for service.
d) ROM fault – Internal non-volatile memory failure, or invalid data image detected. If upload of
audio image or IGRF magnetic field image was recently attempted, retry the upload. Otherwise
return unit to Garmin for service.
e) Execution fault – CPU execution fault has occurred. Cycle power and retry self test. If fault
persists, return unit to Garmin for service.
f) Electrical fault – One of the internal electrical voltages are out of range. Fault will persist until
power is cycled. Check aircraft power supply. If fault persists, return unit to Garmin for service.
Whisper Shout fault – Transmitted power is out of tolerance. Check cable loss configuration,
g)
antenna installation and all cable connections and retry self test. If fault persists, return unit to
Garmin for service.
h) Transmit Power fault - One of the internal transmitter power source voltages are out of range.
Fault will persist until power is cycled. Check aircraft power supply. If fault persists, return unit
to Garmin for service.
i) 1030 MHz Frequency Source fault - Transmit Frequency synthesizer is not locked. Cycle power
and retry self test. If fault persists, return unit to Garmin for service.
j) 1090 MHz Frequency Source fault - Receive Frequency synthesizer is not locked. Cycle power
and retry self test. If fault persists, return unit to Garmin for service.
