1.11.3 Train controls for vertical mode
In Vertical display mode, the scanning beam “swings” in an arc, within the preset sec-
tor (see section 1.13.2). The train control adjusts the bearing in which the scan beam
“swings.”
The train angle moves in 6° steps and can be adjusted in the full 360° spectrum.
The train angle indicator (solid circle) moves to show the starting direction of each
scan.
To increase the bearing, turn the TRAIN knob clockwise.
To decrease the bearing, turn the TRAIN knob counter-clockwise.
1.11.4 Train control for echo sounder mode
In Echo Sounder display mode, the scanning beam is sent in the direction set with the

To move the scanning beam clockwise (in relation to your ship), turn the TRAIN knob
clockwise.
To move the scanning beam counter-clockwise (in relation to your ship), turn the
