For Systems with 3 or More Radios
The Simultalk 24G Pro Series is a multi station team communication system. Each Pro Se-
ries intercom provides the master hands free voice contact with an unlimited number of re-
mote stations. All remotes continuously monitor the master. One at a time, remote users
can switch from standby (listen only) to continuous talk operation.

light.

5. Any REMOTE user may switch to transmit by pressing the talk button. Light will turn
amber.

complete. This allows another REMOTE user to switch to transmit mode.

For SLTi Systems - Wired to Wireless Interface
The SLTi system allows addition of full duplex wireless headsets to most popular wired in-
tercoms without complicated and expensive base stations. The complete system consists
of a Simultalk 24G master transceiver, interface module, and remote Simultalk 24G radios
with headset. The interface includes a software driven circuit that matches the audio levels
if the wireless to that of the wired intercom.
The remote wireless user communicates with the wired party line in a full duplex simultane-
ous talk format just as though they were connected with an actual cable.
