Tilt
The Tilt parameters are accessed from the Horizontal menu.
The Tilt is normally controlled from the Sonar
Operating Panel. On the standard version, the
transducer can be tilted electronically from +10 degrees
up to -60 degrees down, and on the optional 90 degrees
tilt version, it may be tilted down to -90 degrees. In
addition to the readout on the Tilt menu button, the tilt
angle is normally repeated on the tilt indicator in the
upper left corner of the display, and in the vertical
modes; directly in the vertical slice.
Arrows
Manual tilt up/down.
Tilt Step
This button opens a new dialogue to select the tilt steps
in the Auto tilt mode. It can be set from 1 to 10
degrees directly with the increase/decrease function on
the Tilt Step button, or by the - and + buttons in the
Tilt step parameter dialogue.
Tilt Sector
This button opens a new dialogue to select the active tilt sector
in the Auto tilt mode. It can be set from 2 to 100 degrees
directly with the increase/decrease function on the Tilt Sector
button, or by the - and + buttons in the Tilt Sector dialogue.
Manual
In manual mode, the transducer may be tilted within the limits
by pressing the “tilt down” or “tilt up” button.
Auto
In Auto Tilt mode, the transducer will automatically change tilt
angle for each transmission. The change of the tilt angle is
selected by the Tilt Step button, and the total tilt sector is
selected by the Tilt Sector button. The centre of the auto tilt
search can be adjusted with the - (tilt down) or + (tilt up)
buttons. The tilt sector limits will be shown on the tilt indicator
with yellow lines and digits. Note that the auto tilt is working
differently when one of the automatic training programs are
activated (Auto search, Position track or Target track).
The Tilt buttons and the Auto Tilt programs are described in
the Sonar Operator Panel chapter.
