NEDSP1061-KBD Operating Manual
6.1
Introduction.
All functions of the NEDSP1061-KBD are controlled by a
single button.
•
Single press turns the noise cancellation on/off.
•
Holding down the button changes the DSP filter
level.
The mode of operation is indicated both visually and
audibly.
The LED is illuminated red for 4 level mode, or orange for
8 level mode when the noise cancellation is off, and not
illuminated when the noise cancellation is on in 8 level
mode to save on battery life. The LED is green when the
filter is on in 4 level mode.
When the noise cancellation level is changed the LED will
flash green to indicate which level has been selected, and
simultaneously the DSP will beep to give audible indication
of DSP level. This allows the operator to change the DSP
level without having to look at the LED to see which level
has been selected.
A short beep is emitted to acknowledge a button press.
The module will store the current DSP level, and will return
to this level when the equipment is switched on, but
always in the off position.
6.2
Operation.
Switch on the equipment.
The LED will illuminate red or orange to indicate that the
noise cancellation is off. The unit will flash/beep to indicate
the DSP filter level last used.
