  • Notes

  • Central unit is able to call and establish comunication with 5 extensions just by switching a keyboard of 5 positions. Each extension is able to call and speak with the central unit, but not with the other ones. The notice that a call is entering may be given by the same voice of the person who speaks or by means of an auxiliary acustic signal. Button to send an acustic signal is coloured in red. Voice power level is easily ajustable by turning a small round plastic piece coloured also in red (see pictures).

    Central unit requires an electrical suppy of 125 or 220V AC. Extensions don't. To connect them with the central unit, a simple 2 conductors cable (0'5mm2) is enough .

    The price was 5.400 ESP in 1972, but this amount was just for the central unit. Each one of the extensions had an additional suplement of 790 ESP/unit.
