Switching Track Control Off; Adjusting The Offset - JRC ALPHATRON Marine AlphaRiverTrackPilot User Manual

3.3 Switching Track Control Off

To switch the track control system off:
• Select "AUTO" or "WEG" on the autopilot control panel.
• Press "Track" on the touchscreen of the AlphaRiverTrackPilot control panel
If the track control system has been switched off successfully the green light "Run" on the touchscreen changes into red.
For other autopilots, the blue bar on the "Track" button on the touchscreen disappears. It is needed to check if the track
control system is really switched off and the manual steering is functioning as expected.

3.4 Adjusting the Offset

For passing and meeting of other vessels there is an adjustable offset to the guiding line. To adjust the offset move
the joystick on the control panel left or right. The speed of the adjustment is proportional to the angle of the joystick.
The offset can also be adjusted by pressing the corresponding buttons on the touchscreen of the control panel (see
Touchscreen Interface on page 8). To reset the offset to the original line use the button on the touchscreen.
The position of the new parallel line must be checked in the chart display to make sure that the new line is inside the
fairway and does not lead to collisions. The following left picture shows the original guiding line (blue) and the new
parallel line (red) with an offset to starboard. On the right picture, the original guiding line (blue) and the new parallel line
(red) are shown after resetting the offset to zero.
