Common Soft Key Functions
The Probe's innovative Multi-Tasking operating system is
Control Center Softkey Menu
controlled through the Control Center, where several
different screen displays (views) can easily be selected by the
push of a button. Each of these screens (views) reside in the
Probe's internal memory and all are being updated in the
background, regardless of which screen is currently being
displayed. This allows the Probe to provide instant full screen
displays of different features with no data loss on other
screens.
On many of the display screens you will note a recurrence of
the left most soft key labeled "MENU". When the MENU
soft key is pressed, the Probe will return to the Control
Center display. Use of the MENU soft key is required in
order to return to the Control Center where another mode of
operation (i.e. forward looking, track plotting, etc.) can be
chosen.
Power/Backlight Key
Press the "Power/Backlight" key located at the lower right of
the unit to turn the Probe on. The unit will respond with an
audible beep when it turns on. Pressing this key again turns
the backlight on and off, each time accompanied by a beep.
To turn the Probe off, press this key and hold it down for
Typical Sub-Menu
several seconds until the unit goes off.
Demo/Simulator Mode
Your Probe includes a built-in DEMO simulator program
which makes it easy to practice with the unit and to get a
feeling for its many features before actually using it in real
situations on the water. We highly recommend you run
through this section on operation of the Probe with the
DEMO mode activated to first learn basic feature controls.
The DEMO mode can be started from the SETUP menu as
described in the following section.
Split Screen Displays
The Probe has several different split screen display capabilities
such as Split Screen Zoom, Split Screen Chart and Forward
Scan, Split Screen Chart and Track Plot, among others. It is
important to realize that whatever is displayed on the right side
of the display is the PRIMARY information. This means that
when you are in split screen displays, the softkey menus will
usually only relate to the right side of the display.
For example, when you are in the split screen Chart/Track
Plotter display, the Track Plot will appear on the right side of
the display and the softkey menu will allow you to change the
