master station with the capacity of up to 6 total
stations. The system can be designed to meet a
wide variety of needs, including any combination of

annunciated with a momentary electronic mono-tone
and an LED, remaining lit for approximately 20
seconds. Communication at the calling master is
press-to-talk, release-to-listen. Person at the
receiving station speaks hands free. The person at
the master station can selectively call and talk with
