[Emergency mode]

•The emergency mode refers to the state where the VM amplifier is making emergency broadcast or where the "VM amplifier's broadcast cutoff control" signal is being transmitted from external emergency broadcast equipment to the VM amplifier (refer to p. 45 "CONTROL I/O CONNECTOR FUNCTIONS").

•When the VM amplifier is placed in the emergency mode that takes precedence over general-purpose broadcast mode, the Emergency indicators of both the amplifier and the Remote microphone will light.

[Restoration to general-purpose broadcast]

For the general-purpose broadcasts cut off when its mode enters the emergency mode, some are restored after emergency mode completion, and some are not.
