Dcs Series Keysets - Samsung OfficeServ 500 General Description Manual

iDCS KDB-FULL DUPLEX (FKDBF)
This is a daughter board that can be installed only in the 18 or 28 button keyset. The standard speakerphone
mode of operation for a iDCS keyset is "half duplex" . This means that you cannot transmit and receive speech at
the same time. Adding a FKDBF to your keyset will convert the speakerphone into full duplex mode enhancing
its operation. The FKDBF does not require a second "B" channel like the FKDBD or FKDBS and so can be used on a
16 DLI card. In addition the FKDBF may have up to three (3) external microphones attached to it for conference
room type applications. These microphones require an "EXTMIC" key programmed on the keyset to activate or
deactivate them.
Note: Only one KDB can be installed on a keyset.
