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.
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.

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.
