BE 9808 keyboards) can be linked to each main unit bus (PAGING IN 1
and PAGING IN 2).
Every BM 9804 needs a 24 Vdc – 500 mA power supply (not included,

microphone shall be directly powered by the DXT 9000 system main
unit (no need of an external adapter, but it will be necessary to set the
internal switch, as indicated in the previous manual section).
