Setting the Tilt Angle
The tilt angle shows the direction to which the sound wave is emitted. When the
sound wave is emitted horizontally, it is said to be zero (0) degrees and when
emitted vertically, 90 degrees.
To set a tilt angle, operate the TILT lever for the desired angle while watching the
tilt angle indication at the top right corner of the sonar display. Each time the
lever is operated the newly selected tilt angle is displayed in large characters for
five seconds at the top of the sonar display. The tilt angle can be set in
one-degree steps within the range of 0 to 55 degrees.
