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
MENU|MENU. To clear the menu screen and return to the page
display, press
EXIT. (Remember, our text style for MENU|MENU means
"press the Menu key twice." See a full explanation of our instruction
text formatting on page 9, Instructions = Menu Sequences.)
