Full-duplex Speakerphone

Important!
The DKT2020-FDSP’s full-duplex operation depends on the speaker volume setting.
Raising or lowering speaker volume directly affects the performance of the full-duplex
operation.
♦ Depending on the room’s echo characteristics, raising the volume of the
speakerphone can cause the full-duplex operation to deteriorate. When set to
maximum volume, it may be necessary to switch to half-duplex operation.
♦ The speakerphone will automatically reduce volume in each direction when both
the FDSP user and the distant party are talking at the same time. The volume
reduction is required to control the echoes at high volume levels. It is possible for
surrounding conversations and other sounds to trigger this effect even when you
are not speaking.
♦ The performance of the DKT2020-FDSP can vary on calls that involve a delay,
such as wireless calls, Voice Over Internet Protocol calls, etc. With these types of
calls, the quality can diminish.
♦ When using the [PDN] or Intercom button, the performance for internal calls is
not as good as for external calls.
Dip Switches
The DKT2020-FDSP has DIP switches that enable use for the External Microphone
and the international market. The DIP switches are located underneath the flexible
button key strip (see Figure 4).
There are three different DIP switch settings for optimum operation in various types of
environments:
♦ Best – provides full-duplex operation with the Internal or External Microphone.
This is ideal for a large enclosed area, such as an office with little echo. Echo
varies according to the environment. For instance, a room that is relatively empty
has more echo than a room with furniture or items that can absorb sound waves.
♦ Good – provides full-duplex operation with the Internal or External Microphone.
This is ideal for a small office with high echo.
♦ Normal – provides full-duplex operation with the Internal or External
Microphone. This works well with an open office area, such as an office cubicle.
