4.ARROW KEYS – These keys are used to navigate through the menus, make menu selections, move the plotter cursor and sonar chart cursor and enter data.
5.ENT (Enter) – This key allows you to save data, accept values or execute menu commands. It is also used to create event marker icons.
6.EXIT – The Exit key lets you return to the previous screen, clear data or erase a menu.
7.WPT – (Waypoint) The Waypoint key is used to save and recall way- points, search for waypoints and access the waypoint list. It's also in- volved in some navigation functions.
8.ZOUT – (Zoom Out) – This key lets you zoom the screen out. On the Sonar Page, this key returns you to a full sonar chart display, showing the entire water column from surface to bottom. On the Plotter Page, this lets you see a larger geographic area on the display. Less detail is seen as you zoom out.
9.ZIN – (Zoom In) – This key lets you zoom the screen in. On the Sonar Page, this key enlarges fish signals and bottom detail. On the Plotter Page, zooming in lets you see greater detail in a smaller geographic area on the display.
Memory
This unit has permanent memory that saves all user settings, even when power is removed. It does not require, nor does it use an internal backup battery, so you never have to worry about replacement batteries.
Menus
Your sonar unit will work fine right out of the box with the factory default 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 Sec. 4, Advanced Sonar Operation.
Sonar Mode has two primary menus that control its operation. They are the Main Menu and the Sonar 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 ↑ or ↓ to highlight the command and then pressing ENT. To clear the Main Menu screen and return to the Page dis- play, 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 8, Instructions = Menu Sequences.)
