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
LANGUAGE. A display window as shown at right will
pop up on the screen showing the available languages and
the one currently selected. Use the large front panel knob
labeled "BEAM" to change (highlight) the language
selection. Once selected, press any key to save your
selection and exit.

Transducer Alignment

The Twinscope includes a feature that will allow you to
compensate for some transducer installation problems
where the transducer is not pointing straight forward but
instead points off to the right or left of the boat. By
pressing the softkey labeled "ALIGN" an alignment sub-
menu appears that shows arrows to the right and left. This
adjustment will force the unit to move the center point of
its horizontal scan up to 15 degrees to the left or the right.
The number in the softkey indicates the number of degrees
of offset from center with negative numbers indicating the
number of degrees offset to the left and positive numbers
refer to offset to the right. A zero number in the softkey
indicates that the Twinscope is not using any offset. If
you feel you need to adjust the transducer alignment left
or right, point the boat toward a piling or other small
object and then adjust the alignment until the object
appears in the center of the screen. Use either the softkeys
or the "BEAM" knob to adjust.
