" If you have a problem with your PiranhaMax, use the following troubleshooting guide before calling the Customer Resource Center or sending your unit in for repair. You are seeing noise or interference caused by one of several sources. If engine noise is causing the interference, the problem will intensify at higher RPMs. Increase the engine speed with the boat stationary to isolate this cause. If the transducer is mounted too close to the propeller, the turbulence generated can interfere with the sonar signal. Make sure that the transducer is mounted at least 15" (380 mm) from the propeller. Make sure that the SetUp menu is selected, then press the POWER-MENU key until BOTTOM VIEW appears. Bottom View selects the method used to represent the bottom and structure on the display. Structure ID® represents weak returns as light pixels and strong returns as dark pixels. This has the benefit of ensuring that strong returns will be clearly visible on the display. Select a setting from 1-5 to increase or decrease the chart speed, where 1 is the slowest and 5 is the fastest chart speed. Chart speed determines the speed at which the sonar information moves across the display, and consequently the amount of detail shown. A faster speed shows more information and is preferred by most anglers; however, the sonar information moves across the display quickly. A slower speed keeps the information on the display longer, but the bottom and fish details become compressed and may be difficult to interpret. [. . . ] Select either 0 (Off), or 1 through 5 to activate the backlight at the desired level.
