1.11 How to Use the Train Controls
The TRAIN knob selects the direction (bearing) in which the scan beam is output. The
actual beam changes depending on the display mode currently in use.
• Horizontal display mode: Select the center direction (bearing) for the scanning
beam.
• Vertical display mode: Select the bearing for the scanning beam.
• Echo sounder display mode: Select the direction for the sounding beam.
1.11.1 How to change the train direction
Typically, the train moves in a clockwise direction. On occasions where you want to
reconfirm echoes, you can reverse the train direction.
To reverse the train direction, press the REVERSE button ( ).
Each time the button is pressed, the indication "REVERSE" appears for approximately
three seconds at the top of the echo display area, and the train is reversed.
Note: The train reverse function is not available for Echo Sounder mode.
1.11.2 Train controls for horizontal mode
You can change the center direction, or bearing, for the horizontal scanning beam. If
you have a scanning sector set (see section 1.13), the center of the sector moves ac-
cording to the train setting.
The train bearing moves in 6° steps and can be adjusted in the full 360° spectrum.
The train indicator (solid circle) moves to show the bearing graphically. The bearing
indication at the top-left of the screen shows the bearing in degrees.
To increase the bearing, turn the TRAIN knob clockwise.
To decrease the bearing, turn the TRAIN knob counter-clockwise.
