Step 3. If necessary, press the Talk key
5
to make announcements
from the fireman's microphone.
Because the remote microphone set for emergency
operation is given the highest priority, evacuation
guidance messages can be broadcast from the fireman's
microphone even during EV message broadcast.
Note
In Emergency mode, the talk key performs PTT (press-to-
talk) operation regardless of Pc software setting.
3-1. When making microphone announcements over all zones
• Because all zones are pre-selected when in emergency
mode, announcements made from the remote
microphones are broadcast to the entire zone.
• Because the Alert EV message is currently being
broadcast, the left-side microphone Enable lED flashes
green to indicate that priority of current broadcast is
lower than that of microphone announcements.
• The right-side LED indicates the status of microphone
usage. It lights green when the Talk key is pressed.
