if the problem is still present the message may reappear.
8.19 Fault Annunciation
If the transponder detects an internal failure, the screen will indicate FAULT and a brief statement of the
problem. No replies will be made to interrogations when a fault is detected.
Some FAULT indications can be recovered by switching the transponder off and back on again, although in
all cases a FAULT code implies that there is a fault with the transponder or the installation. Note the
FAULT message at the bottom of the screen and pass that information to your avionics maintenance
organisation.
8.20 Low Temperature Operation
The AXP340 is certified to operate correctly down to -25C, but at low temperatures the display may be
impaired. On a cold day you may need to wait for the cockpit to warm up to ensure normal operation.
