Full-duplex Speakerphone
DIP Switches
124 Strata DK Digital Telephone 10/01
➤ To toggle full/half-duplex mode
Notes
● Button 10 functions the same for Internal and/or External Microphone.
● If DIP switch 6 and 7, in Figure 12, are turned Off, the Full/half-duplex function
of Button 10 is disabled and Button 10 will function as programmed in Program
39 of system/station Programming.
● The DKT2020-FDSP’s full-duplex operation depends on the speaker volume
setting. Raising or lowering the speaker volume directly affects the performance
of the full-duplex operation.
Important!
♦ If raising or lowering the volume does not improve performance, switch to half-
duplex mode by pressing Key 10.
♦ If both you and the distant party are using full-duplex speakerphones, the
sensitivity to both echo paths may cause a reduction or instability of volume. If
this happens, it may be necessary to switch to half-duplex mode by pressing key
10.
➤ Press button 10 (see
Figure 9) to turn full-
duplex mode On or
Off.
