Train
The audio channel is displayed as a continuous white line. It can
be trained either manually or automatically. The bearing angle is
displayed in the upper right-hand corner of the display, indicated
relative to the bow.
Manual
In the Manual mode the train left (arrow) or train right (arrow)
buttons are used to direct the audio line to the desired bearing.
Auto search
In the Auto Search mode the sonar will automatically search
within pre-set sector limits with the selected audio line
designating the centre of the search. The search sector is
displayed on the bearing card with two white angular symbols.
 The search sector is adjusted by pressing and holding the
Auto Search button and simultaneously pressing the train
left (arrow) or train right (arrow) buttons .
 The Automatic Search function is overridden when either
the train left (arrow) or train right (arrow) buttons are pressed
and will continue once released. The present bearing at the
moment either button is released will become the centre of
the search.
Position track
The Position Track function is only available when both a
course gyro and a speed log are interfaced with the sonar
system.
To track a fixed position, place the cursor over the desired
location and press the Position Track button. A geographically
fixed circle will appear on the display, and its position will
automatically be tracked by the system with respect to the
bearing and tilt angle.
