The ASP noise rejection feature is especially useful because it typically
lets you operate the boat at all speeds without adjusting the sensitivity
or other controls.
Noise Reject menu.
The ASP feature has four settings — Off, Low, Medium and High.
When first turned on, noise rejection is set on low. If you have high
noise levels, try using the medium or high ASP setting. However, if you
are having trouble with noise, we suggest that you take steps to find
the interference source and fix it, rather than continually using the
unit with the high ASP setting.
There are times when you may want to turn ASP off. This allows you to
view all incoming echoes before they are processed by the ASP feature.
