are in the system.
Screen 1: If One Fault is selected and a fault occurs in an external amplifier,

off. The transmitter is then unmuted and any external amplifiers (fully or
partially operational) are enabled.
Screen 2: If Three Fault is selected and a fault occurs in an external
amplifier, the entire transmitter is muted and unmuted three times before the
faulted external amplifier is latched off.
NOTE: Faulted amplifier sections are re-enabled when latched faults are
cleared in the event log. See Table 9.1 for more information on clearing the
logs.
