You can customize the sounder by choosing what is displayed and
how it is displayed (including language and units). For example,
you can set the scroll speed of the bottom graph display, and you
can select the range to adjust the depth displayed.
You can view the cursor position and a variety of data (such as
speed and depth) from the transducer and other equipment in user-
selectable data boxes. These data boxes can be moved around the
screen and they can be switched on or off.
Chapter 3 includes details on adjusting the display, other set up
options are described in Section 4.4.
