WARNING!This device should not be used as a navigational aid to prevent collision, grounding, boat damage, or personal injury. [. . . ] A right or left arrow on a menu choice means that you can use the RIGHT or LEFT Cursor keys to make changes or to see more information. NOTE: The Main Menu choices will vary depending on whether you are in Normal or Advanced User Mode. Main Menu System Normal User Mode FF595c Title Screen The Menu System The menu system is divided into easy-to-use menu modules. The main components of the menu system are: Start-Up Options Menu - Press the MENU key during the power up sequence to view the Start-Up Options menu. X-PressTM Menu - The X-PressTM Menu allows you to access the settings that are changed frequently without having to navigate through the whole menu system. Press the MENU key once to display the X-PressTM Menu. When you select a menu item from the X-PressTM Menu, the menu will collapse, leaving only the menu choice on the screen. Use the Up or Down Cursor keys to reactivate the X-PressTM Menu. X-PressTM Menu NOTE: The X-PressTM Menu choices will vary depending on which view is active when you press the MENU key, as well as whether you are in Normal or Advanced User Mode. Either the Sonar or Navigation X-PressTM Menu will appear, depending on the view you are in. User Mode (Normal or Advanced) - An Advanced Mode is provided for users who desire the highest level of control over the FishFinder and Normal Mode for users who desire greater simplicity and fewer menu choices. Additional Advanced menu choices will be displayed throughout the menu system when you navigate to specific menus while in Advanced Mode. Any changes made while in Advanced Mode will remain in effect after you switch back to Normal Mode. See Setup Menu Tab: User Mode for specific instructions on changing to Advanced User Mode. Sonar Tab, Normal Mode Main Menu Tabs - Less frequently-adjusted menus are grouped into the Main Menu System. A 3D or Enhanced Fix is required for navigation. HDOP (the Horizontal Dilution of Precision) is a GPS system parameter which depends on the current satellite configuration. HDOP is used to calculate the Estimated Position Error.

Increasing the sensitivity shows more sonar returns from small baitfish and suspended debris in the water; however, the display may become too cluttered. When operating in very clear water or greater depths, increased sensitivity shows weaker returns that may be of interest. Decreasing the sensitivity eliminates the clutter from the display that is sometimes present in murky or muddy water. If Sensitivity is adjusted too low, the display may not show many sonar returns that could be fish. Upper Range (Advanced: Sonar, Split Sonar and Big Digits Views Only) Upper Range sets the shallowest depth range that will be displayed on the Sonar, Split Sonar and Big Digits Views. The Upper Range menu choice is available when User Mode is set to Advanced (see Setup Menu Tab: User Mode) and can only be accessed from the Sonar, Split Sonar and Big Digits Views. Upper Range is often used with Lower Range. For example, if you are only interested in the area between 20 and 50 feet deep, you should set the Upper Depth Range to 20 and the Lower Depth Range to 50. The Sonar View will then show the 30 foot area between 20 and 50, and will not show the surface or the bottom (assuming the bottom is deeper than 50 feet), and will show greater detail for that area between 20 and 50 feet. NOTE: A minimum distance of 10 feet will be maintained between the Upper and Lower Range regardless of the manual settings entered. To adjust the Upper Range: 1. [. . . ] One or more of the following sources can cause noise or interference: Possible Source of Noise Problem The control head loses power at high speeds. Isolation Turn off any nearby electronic devices to see if the problem goes away, then turn them on one at a time to see if the noise re-appears. To determine whether the boat's engine is the source of the noise, increase the RPMs while the boat is in neutral and stationary to see if the noise increases proportionately; if noise appears when you rev the engine, the problem could be the spark plugs, alternator, or tachometer wiring. Replace the spark plugs with resistor plugs, install an alternator filter, or route the control head power and transducer cables away from the engine wiring. Turbulence created by the propeller can cause noise; make sure the transducer is mounted at least 15" (38 cm) from the propeller, and that the water flows smoothly over the face of the transducer at all times. Possible Cause If the power output of your boat's engine is unregulated, the control head may be protecting itself using its overvoltage protection feature. [. . . ]
