FAILSAFE WARN AUDIO IN HI
These are unswitched inputs intended for use with alert sources such as altitude, terrain, auto-pilot or other
aural status indications.
FAILSAFE WARN AUDIO IN HI is heard during normal operation as a fifth alert input.
CAUTION
During failsafe mode both FAILSAFE WARN AUDIO IN HI and COM 1 AUDIO INPUT
are connected to the PILOT HEADSET LEFT OUTPUT. During this time the output of the
COM 1 radio and the output of the device connected to FAILSAFE WARN AUDIO IN HI
will become shorted together, potentially causing damage or interference. If the
FAILSAFE WARN AUDIO IN HI is used, it may be necessary to install summing resistors
in series between these sources and the inputs to the audio panel to protect the outputs
from damage.
