The ASP feature has two levels -
Normal and High. If you have high
noise levels, try using the “High” ASP
setting. However, if you are having
trouble with noise, we suggest that
you take steps to find the interference

setting. However, there are times when
you may want to turn the ASP feature
off. This allows you to view all incom-
