Menus

Your sonar unit will work fine right out of the box with the factory de- fault settings. You only need to learn a few basic functions to enhance your viewing. We'll discuss them briefly here, then talk about them and all the other commands in more detail in the next section, which begins on page 49.

Your unit has three primary menus that control its operation. They are the Main Menu, the Sonar Menu and the Pages Menu.

Main Menu

The Main Menu contains some basic function commands and some setup option commands. You access the Main Menu by pressing MENUMENU. You run a command by using the ↑ or ↓ to highlight the command and then pressing ENT. To clear the Main 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 instruc- tion text formatting on page 4, Instructions = Menu Sequences.)
