Station Apparatus

2000-series Telephones

To toggle full/half-duplex mode

Press button 10 (see Figure 11-41) 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.
