Power/lights on and off
To turn on the unit, press PWR.
To change the backlight, press
PWR again. The X102C and X107CDF
have three backlight levels. Repeatedly pressing
PWR will cycle through
the backlight settings, turn off the backlight, then turn it back on
again.
Turn off the unit by pressing and holding the
PWR key for about 3 seconds.
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 45.
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
MENU|MENU.
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 "MENU|MENU"
means "press the Menu key twice." See a full explanation of our instruc-
tion text formatting on page 4, Instructions = Menu Sequences.)
