"OK" displayed when the "GOOD" column shows that the number of satellites acquired is five or more.

"3D" shown when no beacon receiver is used.

Satellite tracking status display

When the system is turned on for the first time it is in the “cold-start” state, which means there is no satellite data (almanac data) stored. In this condition it takes about 20 minutes to find heading. When heading is found the display shows “OK.” The timer at the top left corner of the screen shows time since power on. If OK is not displayed within 30 minutes after turning on the power, the antenna mounting location may not be suitable. Suspect that the number of satellites in view is less than five due to signal blockage. Resolve the problem and then recheck tracking status.

If the heading error is between 5° and 10°, adjust orientation of the antenna unit, while watching the heading indication on the display. (For the open-type antenna, loosen the nut at the center of the antenna unit to adjust antenna orientation.)

2.6.2Choosing heading source

Choose the source of heading data as below.

CAUTION

Never switch from internal to external heading while the autopilot is in the automatic mode. Change to the manual mode before switching.
