User manual HUMMINBIRD PIRANHAMAX 10

[. . . ] Disassembly and repair of this electronic unit should only be performed by authorized service personnel. Any modification of the serial number or attempt to repair the original equipment or accessories by unauthorized individuals will void the warranty. Handling and/or opening this unit may result in exposure to lead, in the form of solder. This product contains lead, a chemical known to the state of California to cause cancer, birth defects and other reproductive harm. [. . . ] 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 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. 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. [. . . ] 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. This warranty is included by your local distributor and this distributor maintains local service for your unit.
