MANUAL TRAINING
In manual training, the audio channel can be trained
continuously in either direction to the wanted bearing. The
automatic training programme is overridden when the manual
training knob is operated. When the activated button is released,
the automatic search will continue. The bearing at the moment
when the button was released will then be the new centre bearing
of the search area.
AUTO SEARCH
In this mode the sonar will automatically search within the sector
set by the search sector buttons.
The bearing at the time of pressing the button will be the centre
of the search area.
The AUTO SEARCH button also has a stop/return function,
which means that if the button is held in the inner position, the
search will stop, and when it is released again, it will train in the
opposite direction.
