The LiberatorMAX Fire Headset is used in conjunction
with an MS-900MAX Base Unit and up to 6 additional
headsets to form a wireless intercom network that also
allows Radio Transmit headsets to operate a vehicle-
mounted mobile radio remotely.
Only the Radio Transmit headsets allow the user to
talk over the mobile radio, however all headsets on the
channel will hear received audio from the mobile radio
and from all other headsets on the channel.
The headsets and Base Unit can operate on any one
of 8 available channels – all headsets must be on the
same channel for network intercom operation.
A Portable Radio can be connected to the Headset
using a PRAC Cable. The Portable Radio will connect
exclusively to that headset – other headsets in the
group will not hear the received audio or be able to
transmit over the portable radio.
Instructions for using the LiberatorMAX headsets
with the MS-900MAX Radio Interface Base Unit can
be found in the MS-900MAX User Guide.
