Main Menu
The unit has a Main Menu, which contains some function and setup commands. The instructions in this section will deal only with sonar functions, the basic commands that make the unit show sonar signals on your screen. This unit will work fine right out of the box with the factory default settings. But, if you want to learn about the various sonar options, see Sec. 4, Sonar Options & Other Features. (For general system setup and GPS options, see Sec. 8, System Setup and GPS Setup Options.)
You can access the Main Menu from any of the four Page screens by pressing MENUMENU. To clear the menu screen and return to the page display, press EXIT. (Remember, our text style for MENUMENU means "press the Menu key twice." See a full explanation of our instruction text formatting on page 9, Instructions = Menu Sequences.)
