ACTIVE VOX (VOICE ACTIVATED CIRCUIT) LED INDICATOR:
A
Each LED is associated with a voice communications port (radio, telephone). When the port
receives audio from the radio or other connected device, the LED will light as the audio is received at
the ICRI circuitry. The LED should light as each word is spoken. To adjust the level of the incoming
audio, adjust the volume control of the device connected to the ICRI.
TALK GROUP SWITCH:
B
The talk group switches determine which communications devices will be connected/interoperate
each other. Only the radios, telephone, or handset connected to a specific talk group will hear or be
able to transmit audio to the other individuals connected to that talk group. The switch corresponds
to the interface jacks below it. Radios/interfaces DO NOT need to be turned off or disconnected to
switch talk groups.
UP: Talk Group 1
CENTER: Not connected to either talk group
DOWN: Talk Group 2
ON-OFF SWITCH:
C
This switch is used to turn the ICRI ON and OFF; there is no delay between ―POWER ON‖ and
radio link.
