1.2.4 Gain adjustment
The receiving gain is adjusted by the GAIN keys ( and ) of the controller.
The gain can be set in the range of 0.0 to 10.0 The gain is raised by the key
and lowered by the key. The gain is adjusted such that the fish school echo
clearly appears on the screen and the noise is minimized. In addition, this instrument
executes the gain control for the TVG; if the distance is increased, the gain is
automatically increased. By virtue of this, fish schools at both long distance and short
distance are displayed similarly on the screen.
1.2.5 Tilt adjustment
The tilt is adjusted by the tilt keys ( and ) of the controller. The tilt can be set
by 1° (degree) in the range from +5° (to the upward direction from the horizontal
direction) to -60° (to the downward direction from the horizontal direction).
The tilt is adjusted to the upward direction by the key and adjusted to the
downward direction by the key. The angle is adjusted to the direction where you
want to search for fish schools.
For the tilt adjustment operation, there are four modes: Manual, Auto, One shot, and
Track.
1.2.6 Range adjustment
The range can be adjusted with the range keys ( and ) of the controller.
The range can be set to a long distance with the range key and to a short
distance with the range key. These keys can be used to adjust the fish school
detection range.
