In the latter case, the incoming message is broadcast simultaneously by the integrated
and auxiliary amplifiers, but only before pressing of DWEx key to respond the call. After
the response, the auxiliary amplifier is turned off, and the calls are only broadcast to the
integrated amplifier. It is turned on again after a predetermined interval after the end of the
communication session (usually 15 seconds).
The operating mode and the output delay value for the auxiliary amplifier are specified
in the unit configuration data using the communication system administration software. The
volume control of the auxiliary amplifier is on the KIB board (see Figure 3).
