Х4, X5 – sockets for built-in loudspeakers;
Х6…Х9 – sockets for connecting button modules;
Х10 – the "LINE" connector of the RJ-45 type for connecting the Uk0 interface
cable, the power supply of the device and an additional (external) amplifier;
Х11 – socket for DIS expansion unit when it is used;
ХР1 – microprocessor programming connector D3 (technological);
ХР2 – microprocessor programming connector D2 (technological);
ХР5 – FPGA programming connector D4 (technological);
SW1 – D3 microprocessor reset button (technological);
SW2 – the reset button of the microprocessor D2 (technological);
Two-position DIP switch SW3 volume control modes, with the following
functions:
SW3.1 – is intended to enable the volume control function of DIS loudspeakers
without programming this function from the control panel, to this end, it must
be set to the ON position. In this case, the volume is reduced by sequentially
pressing the seventh button located on the DIS in the bottom row (the
numbering of the buttons goes from left to right and from bottom to top), the
volume increase is the eighth button. To disable this mode, set the switch to the
OFF position, after which both buttons will be available for use in the usual way.
SW3.2 – not used;
SW4 – button to reset the connection with the switch;
R73 – tuning resistor for adjusting the sensitivity of the main microphone during
duplex communication in Handsfree mode;
R76 – tuning resistor for adjusting the sensitivity of the headset microphone
(remote microphone with a tangent);
R78 – tuning resistor for adjusting the sensitivity of the main microphone during
outgoing simplex communication;
R104 – a tuning resistor for adjusting the Handsfree circuit;
FU1…FU6 – line of fuses for main and “Phantom” power supply lines.
