2.3.4Adjusting for orientation error

It may be impossible to perfectly align the processor unit on the fore-and-aft or port-and-starboard line. Open the top cover, loosen the two fixing screws on the angular rate sensor and turn. For example, if the orientation error is 2.5° to port, rotate the sensor 2.5° starboard. The range of adjustment is -45°to +45°. Close the top cover after completing the adjustment.
