1. PWR/CLEAR
This key appears in the manual text simply as PWR. Press this key to turn the unit on and off. It also clears menu selections and the menus from the screen. To clear a menu from the screen, press PWR one time.
NOTE:
Hold the PWR key down for five seconds to turn off the unit.
2.MENU UP
3.MENU DOWN
These keys appear in the manual text as MENU UP or MENU DOWN. Most of the time, the instructions require you to press either menu key, so the text simply uses the word MENU. Usually, when we say MENU, you can simply press the MENU UP key for consistency.
This sonar unit has many features that are accessed with the menu keys. The MENU UP key moves up or forward through the menus, the MENU DOWN key moves down or backward. To see the first menu, simply press either MENU key. To see the other menus, press a MENU key repeatedly to cycle through the menu list.
4. UP & DOWN ARROWS
These keys appear in the manual text as DOWN ARROW or UP ARROW. Use these keys to adjust virtually every feature and function on the sonar unit.
