Mark Key; Goto Key; Zoom (+/-) Key; Exit Key - Humminbird 500 SERIES 580 Operation Manual

MARK Key

Press the MARK key while in any view to mark the position of a
waypoint, either at the current boat location, or, if the Cursor is
active, at the current Cursor location.
The MARK key only functions if you have the GPS receiver connected.

GOTO Key

If the Cursor is active, pressing the GOTO key while in any view
creates a waypoint and starts navigation towards that waypoint. If
the Cursor is not active, pressing the GOTO key displays the list of
waypoints, so that you can select the waypoint towards which you
want to navigate.

EXIT Key

The EXIT key has multiple functions, depending on the situation:
• If an alarm is sounding, pressing EXIT will cancel the alarm.
• If a menu tab is selected, pressing EXIT will exit the menu mode and
return to the view.
• If a menu is active, pressing EXIT will return to the previous level in the
menu system.
• Pressing EXIT will cycle through the available views in reverse order.
• If Freeze Frame is active, pressing EXIT will return to a scrolling display.
• If the Cursor is active, pressing EXIT will remove the cursor from the
display.

ZOOM (+/-) Key

Press the - or + ZOOM keys while in any of the Navigation
Views or the Sonar Zoom View to change the scale of the
view to appear closer or farther away.
