SonarPhone SP100, Руководство пользователя

Страница: 11 / 38

Press the "Beam Angle Select / Return" button on the SP200/SP300
touch pad. During normal operation, this button switches
back-and-forth between the the wide 40 degree cone and the narrow
20 degree cone.
IMPORTANT: You will need to increase the gain level while using
the wide 40 degree much more than when using the narrow 20 degree
beam. This is normal because you are covering twice as much area
with the wider beam.
