PRO TIP:
You can press multiple radio buttons at the same time, enabling transmission on multiple radios simultaneously. All

RADIO SELECT LED BUTTONS:
Green LED:
The Digital Intercom allows the user to select the transmit radio by pressing one of the Radio buttons. A green LED will
indicate which radio is the transmit radio. This radio will be used when any user presses the PTT button on their headset.
To select another radio as the transmit radio, simply press the button that corresponds to that radio and the new radio
button green LED will light, indicating that it is the transmit radio. Unless you press and hold multiple radio buttons, only
a single radio will be designated the transmit radio. Selecting one radio as the transmit radio deselects the previous
transmit radio.
Yellow LED:
The Digital Intercom allows the user to monitor traffic from multiple radios. All active radios are indicated with a yellow
LED. Any radio button with a yellow LED indicates that audio from that radio can be heard by everybody wearing a
headset. This allows multiple radios to be monitored simultaneously.
When a radio has too much traffic and is distracting, it can be deactivated by pressing and holding the radio button for 3
seconds. This will turn off the yellow LED and no audio from that radio will be heard by the users.
Red LED:
When a user is transmitting on a radio a red LED will light up on that radio button for the duration of the transmission.
The red LED provides indication that a radio transmission is occurring.
Blue LED:
The Digital Intercom monitors audio on all radio channels and a blue LED indicates audio traffic on a radio. This is useful
when a radio has been deactivated. On deactivated radios the blue LED will light indicating that unheard audio traffic is
occurring on that radio.
