transducer mark at the top left corner on the screen. See section 1.4.3.
In normal use, fully lower the transducer. The time required to fully lower the transduc-
er is approx. 12 seconds for full protrusion in case of 1200 mm stroke and 16 seconds
in case of 1600 mm stroke.
If the transducer becomes entangled in the net for some reason, partially raise the
transducer with the
