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, indicated by displaying “OK.” (Once almanac
data is stored it takes about five minutes to find heading.) 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. It is suspected that the number of satellites in view is less than five due
to signal blockage. Clear the problem and then check status on the status
display.
If the heading error is between 5° and 10°, loosen the nut at the center of the
antenna unit and adjust antenna orientation, while watching the heading
indication on the display.
