8.1. Introduction
・
The following settings that affect the way the equipment operates can be made via a
menu system consisting of a main menu (
MAIN MENU )
and a number of associated
submenus accessible through main menu options:
- settings that you do not have to change frequently, such as the transducer draft and
echo threshold level, and
- settings that should be made mainly at initial installation time, such as depth readout
unit, keel offset and local time offset.
・
To activate the menu system, simply press

. This opens the MAIN MENU , as
illustrated below.
・
A second keypress turns it off.

8.2. Entering Transducer Draft
8.2.1. Introduction
・
The transducer draft used in this manual refers to the depth from the water surface to
the transducer face, as defined in
Figure 8–2.
・
The depth readout shown on the screen initially represents the depth to the bottom,
measured from the transducer face (depth–below–transducer or
DBT )
.
・
If you wish to read depths from the waterline (to agree with spot soundings or bathymetric
data on official charts)
, you have to add the draft to the on–screen depth readout.
・
The following procedure will allow you to enter the desired draft in 0.1–unit steps
(0.1–meter / fathom / foot steps)
so that both digital depth readout and graphical indication
reflect the draft, automatically reading depth from the waterline.
< WAR NING >
WITH A TRANSDUCER DRAFT ENTERED, THE ON–SCREEN DIGITAL READOUT
SHOWS THE DEPTH FROM THE WATERLINE AND NOT FROM THE KEEL.
GREAT CARE SHOULD, THEREFORE, BE TAKEN IN USING DEPTH DATA WHEN
NAVIGATING SHALLOW WATER AREAS.
NOTE: To read depth from the keel, you must first register the keel offset (distance from the transducer face to the keel).
Refer to paragraph 8.10.7.3 for details.
