FELCOM 82
H3-2
2. System settings
2.1 Heading alignment
The system detects the heading direction at every power-up by using the limit switch in
the antenna unit. The switch is factory-adjusted so that the antenna is installed with the
access hatch located in the stern. When the antenna unit is installed with a directional
offset of 90, 180 or 270 degrees, following adjustment is necessary.
1. Mark the four screw locations on the disk.
2. Loosen the four screws fixing the disk.
3. Rotate the disk according to the access hatch position. For example, if the hatch is
located on the starboard side, rotate the disk 90 degrees counter clockwise.
4. Tighten the screws.
5. Confirm that the limit switch hits when the antenna points toward the ship’s bow.
