Demonstration 2.
The module switches
the noise cancellation
on for 3 seconds then
off for 3 seconds. This
is a good demonstra-
tion of the before and
after effects of remov-
ing the noise.
Demonstration 1.
The module switches the
noise cancellation on for 1.5
seconds, then off for 1.5
seconds. It will then move to
the next level and repeat the
process.
This mode is particularly
effective at demonstrating the
different DSP levels.
Alternatively pass a clean
audio signal through the
module to see hear how little
the DSP alters the speech.
Note:
To exit the demonstra-
tion modes hold down
the DSP button until a
2 tone beep is heard.
