➤ To toggle full/half-duplex mode
➤ Press button 10 (see Figure 8-41) to turn full-duplex mode On or Off.
Full-duplex mode: Button 10 LED Off.
Half-duplex mode: Button 10 LED On.
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.
● 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.
