This automatic feature gives you the best display possible under most conditions. It is caused by electrical and mechanical sources such as bilge pumps, engine ignition systems and wiring, air bubbles passing over the face of the transducer, even vibration from the engine. 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 source and fix it, rather than continually using the unit with the high ASP setting. This allows you to view all incoming echoes before they are processed by the ASP feature. Sonar Menu with Sonar Features selected (left).

Alarms This unit has three different types of sonar alarms. It sounds when the Fish I. D. TM feature determines that an echo is a fish. Another alarm is the Zone Alarm, which consists of a bar on the side of the screen. Any echo on the chart that appears inside this bar triggers this alarm. The last alarm is the Depth Alarm, which has both a Shallow and a Deep setting. This is useful as an anchor watch, a shallow water alert or for navigation. Depth Alarms The depth alarms sound a tone when the bottom signal goes shallower than the shallow alarm's setting or deeper than the deep alarm's setting. For example, if you set the shallow alarm to 10 feet, the alarm will sound a tone if the bottom signal is less than 10 feet. It sounds a warning tone if the bottom depth goes deeper than the alarm's setting. These alarms can be used at the same time or individually. Main Menu with Sonar Alarms command highlighted (left). Press the ALARM key on the front of the unit or press MENU|MENU and use or to select Sonar Alarms, then press ENT. Press or to change the first number, then press to move the cursor to the next number and repeat until the depth is correct, then press ENT.
