[. . . ] Select Off for no fish alarm, or one of the following symbols to set the alarm. An alarm will sound when the PiranhaMax detects fish that correspond to the alarm setting. Fish Alarm will only sound if Fish ID+ is also set to On. An audible alarm sounds when the depth is equal to or less than the setting. Filter adjusts the sonar filter to limit interference on the display from sources such as your boat engine, turbulence, or other sonar devices. (Off, On, Default = Off) When you choose SetUp, additional menu choices will become available that are not a part of the Main Menu system. After selecting SetUp, press the POWER-MENU key to display the SetUp menu choices, one at a time. (Setting Saved in Memory) Make sure that the SetUp menu is selected, then press the POWER-MENU key until CONTRAST appears. (Setting Saved in Memory) Make sure that the SetUp menu is selected, then press the POWER-MENU key until FISH ID+ appears. Select either Off to view "raw" sonar returns from the 200 kHz narrow beam, or On to view Fish symbols. Fish ID+ uses advanced signal processing to interpret sonar returns, and will display a Fish Symbol when very selective requirements are met. A select number of possible fish returns will be displayed with their associated depth. NOTE: Returns from the 200 kHz narrow beam are shown with shaded fish symbols while the 83 kHz wide beam returns are displayed with hollow fish symbols. NOTE: Hollow fish symbols are only available on 200/83 kHz Dual Beam sonar units. (Setting Saved in Memory) 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. Black (Bottom Black) displays all pixels below the bottom contour as black, regardless of signal strength. This has the benefit of providing a high contrast between the bottom and other sonar returns on the display. This has the benefit of clearly defining the bottom on the display. Inverse is a method where weak returns are shown with dark pixels and strong returns with lighter pixels. [. . . ] If the connector is reversed, the unit will not work. Examine the contacts on the back of the unit to ensure there is no corrosion. When powering on, if a message indicates "transducer not connected", make sure that an appropriate transducer connector is plugged into the unit. If the transducer is connected to the unit through a switch, temporarily connect it directly to the unit and try again. [. . . ]
