2.10 Handset/Headset Operation
The CS-812 console has the ability to connect either an ETC handset (TH-3) or a Mono headset through a
RJ-25 jack on the back of the device. Once a handset is connected the unit will show a “H” icon in the
status bar to indicate the unit is now in Handset or Headset mode.
To transmit on a specific channel, the operator needs to first select a channel by pressing the respective
Volume Control/PTT button (aka VCB). This channel will have a visual indication in a form of a checkbox.
User can now simply press the PTT button on the ETC Handset or the Headset Belt Pack PTT button to
transmit on the selected channel. The VCB can also be used to transmit on any channel including the
selected on using the gooseneck microphone.
PLEASE NOTE:
Incoming audio of the selected channel will go to the handset only for privacy of the conversation. All
other channels will still be transmitted out of the built-in speaker.
Shall the user want to receive all incoming audio on the built-in speaker the F3 button may be pressed to
disable the privacy function (selected channel incoming audio being routed to the Handset or Mono
Headset only). H->S symbol will be displayed on the status bar to indicate all audio is being routed to the
built-in speaker.
The operator can press the F3 button to reengage/toggle standard ETC Handset or Mono Headset
