Common Soft Key Functions
Control Center Softkey Menu
The Twinscope's innovative Multi-Tasking operating system
is 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
Twinscope's internal memory and all are being updated in the
background, regardless of which screen is currently being
displayed. This allows the Twinscope 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 Twinscope 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 Twinscope 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.
Typical Sub-Menu
To turn the Twinscope off, press this key and hold it down for
several seconds until the unit goes off.
Demo/Simulator Mode
Your Twinscope 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 Twinscope 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 Twinscope 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.
