Power/lights on and off
To turn on the unit, press PWR.
To change the backlight, press PWR again. The X125 and X126DF have two backlight levels to select from. The X135 and X136DF have three backlight levels. Repeatedly pressing PWR will cycle through the back- light 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 43.
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 5, Instructions = Menu Sequences.)
