Set-Up View
The Twinscope includes a SET-UP View where the
DEMO program can be activated, the units of measure and
language can be selected and the display contrast can be
adjusted. The Twinscope's internal backup battery will
remember all settings for future use.
From the Control Center press the button below the SET-
UP soft key twice to put the display into the SET-UP
View. Then press the button below the “GO” soft key to
use this view. The display should appear as on the left.
Demo Program
We highly recommend you initially operate the Twinscope
in the DEMO mode to familiarize yourself with the many
advanced features of the Twinscope. When using the SET-
UP view, press and hold the soft key below DEMO until
the unit beeps twice and the word “DEMO” on the display
changes to reverse video as shown at left. This will activate
the simulator program. The unit will automatically cycle
through a simulated demonstration of its many features. At
any time, you can press any key to gain control of the
DEMO program to make your own selections and
adjustments. If you do not press any button for about 45
seconds, the unit will automatically resume cycling through
the different demo features on its own.
The pictures shown in the DEMO mode are representations
of what you might see on your Twinscope. In actual use,
the picture you will get can vary significantly depending on
depth, bottom and water conditions, the speed of your boat
and many other factors (see Interpreting The Twinscope’s
Forward Display, beginning on page 67).
To exit the DEMO program either turn the Twinscope off
and back on again, or press the “DEMO” soft key again.
Select Units of Measure
The Twinscope starts with the last units of measure
selected. By pressing the button indicated on the display,
you can use the large front panel knob to choose between
U.S., Nautical and Metric units. Rotate the front panel
knob to select (highlight) the type of display units desired.
Once selected, press any button to save your selection and
exit. The current choice is displayed each time the
“UNITS” soft key is pressed.
