Noise Rejection menu.
The ASP noise rejection feature is especially useful because, typically, it lets you operate the boat at all speeds without adjusting the sensi- tivity or other controls.
The ASP feature has three settings — Off, Low and High. When first turned on, noise rejection is set on low. If you have high noise levels, try using the high ASP setting. If, however, you are having trouble with noise, we suggest 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 off ASP. This al- lows you to view all incoming echoes before they are processed by the ASP feature.
To change the ASP setting, repeatedly press MENU until the NOISE REJECTION menu appears. Use ↑ ↓ to select the desired setting, then press PWR to clear the menu.
