Table 2. Tone and noise reduction levels.
The column marked level (4) shows the noise and tone
reduction when operating the module with 4 levels, and
the level (8) column for 8 levels.
Holding down the DSP select button will continuously
change the DSP level. When the desired level has been
reached, release the button. The module will retain this
level until it is changed.
The
ANEM
is factory set up and ready for use. If you are
using the module in an application which requires
adjustment. For the optimum performance refer to section
