Select Menu Language
The Twinscope allows the selection of 9 operating
languages; English, French, Italian, Spanish, German,
Danish, Finnish, Swedish and Greek may be chosen. To
select the operating language, press the button labeled
LANG . A display window as shown at right will pop up
on the screen showing the available languages and the one
currently selected. Rotate the large front panel knob to
change (highlight) the language selection. Once selected,
press any key to save your selection and exit.
Transducer Level Adjustment
The Twinscope also includes an adjustment to
compensate for transducer installation problems,
especially thru-hull installations, where the transducer is
not perfectly vertical to the water’s surface. This problem
can be caused by improper installation, or by changes in
the boats fore/aft weight.
When the boat is over a known level bottom, the forward
display should show a level line. If the bottom display is
slanted upward or downward (as in the pictures at right),
Press the button labeled “
LEVEL ” in the SET-UP View
as shown at right above. In the LEVEL menu, notice the
number which indicates the relative amount of correction
in degrees. It is possible to /- 15 degrees. Positive
numbers will tend to make the bottom slope upwards and
negative numbers will make the bottom slope downwards.
After making the adjustment, go to the forward display
and verify the correction. Once adjusted, the
Twinscope’s
memory will retain the setting.
