SSC200 User’s Manual Page 12 Revision 1.8 4. While continuing to turn the vessel as indicated in step 3, remove the power from the compass and reapply power (this in itiates deviation calibration). 5. Continue turning the vessel through four complete circles in less than 10 minutes from the time power was applied.
Revision 1.8 Page 13 ® ® 2. With the vessel laying flat in the water, adjust the pitch ang le of the SSC200 by adding small washers or spacers between the mounting bracket holes and mounting surface until the display reads zero for the pitch angle (skip this step if you are not interested in viewing the vessel’s pitch angle).
