BUTTON or PUSH-TO-TALK JACK is used. The PUSH-TO-TALK BUTTON can be
used by the operator to cut off the entertainment even if the operator is connected in
the Full Duplex (4-Wire) mode.
WARNING!
The AUXILIARY AUDIO INPUT is not electrically isolated from the circuitry of the 2810E-02. Any external
equipment connected to the input should not be AC powered or connected to the AC mains indirectly
through any equipment without the proper isolation. Failure to follow this warning may result in
electrocution or death.
WARNING!
To ensure clear communications when using the AUXILIARY AUDIO INPUT, it is critical that the volume
level of the external audio device be set at a level below that of the operator's microphone as described
above. It is recommended that the operator use the PUSH-TO-TALK BUTTON when talking to the
occupant(s) as this cuts off the signal from the AUXILIARY AUDIO INPUT.
CHAMBER CONNECTIONS
2.2
The chamber connections are located on the rear left side of the communicator.
CHAMBER MICROPHONE - This is a dual banana jack (color-coded red) that functions as
both an output (earphone) and input (microphone) for the chamber occupants as controlled
by the PUSH-TO-TALK BUTTON and PUSH-TO-TALK JACK. Using this connection, the
chamber can be wired in either 2-Wire or Full Duplex (4-Wire) mode regardless of the mode
used for the operator.
2.2.1
Full Duplex (4-Wire) Mode
Connect the chamber microphone red banana plug (AUDIO UPLINK) to the red
jack located on rear side of chassis and the chamber earphone black banana plug
(AUDIO DOWNLINK) to the black jack located on rear side of chassis. Occupants
can use this mode even if the operator is wired in 2-Wire mode, for example, to
take advantage of the audio entertainment feature of the 2810E-02.
2.2.2
2-Wire Mode
Double stack the chamber microphone (red banana plug) and the earphone (black
banana plug) to the red jack located on the rear side of chassis. If occupants are
using a headset, connect both the headset microphone and earphone to this jack.
In this mode, the chamber speaker will act as a microphone and be heard on
operator’s headset and/or PANEL SPEAKER unless the PUSH-TO-TALK
BUTTON or PUSH-TO-TALK JACK is activated.
2.2.3
CHAMBER EARPHONE - This is a dual banana jack (color-coded black) that
functions as the output for chamber occupant’s earphone. It is only used when the
chamber is in Full Duplex (4-Wire) mode.
