Use ^ to select ON, which will turn on the alarm, then press PWR to clear the menu. If the voltage value falls below the alarm’s setting, the alarm will sound and a message will appear on the screen. Noise Rejection and ASP™ The ASP™ (Advanced Signal Processing) feature is a noise rejection system built into the sonar unit. It constantly evaluates the effects of boat speed, water conditions and electrical interference and automatically gives you the best display possible under most conditions. ASP is an effective tool in combating noise. In sonar terms, noise is any undesired signal. It is caused by electrical and mechanical sources such as bilge pumps, engine ignition systems, wiring, air bubbles passing over the face of the transducer and even vibration from the engine. In all cases, noise can produce unwanted marks on the display. The ASP noise rejection feature is especially useful because, typically, it lets you operate the boat at all speeds without adjusting the sensitivity or other controls. 53 Noise Rejection menu. 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 allows 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 ^v to select the desired setting, then press PWR to clear the menu.
