After the Board has been reset to the DEFAULT values, the GPS receiver
requires up to 13 minutes of satellite reception to determine the correct leap
second information from the GPS data. The Board 6021GPS can only re-
synchronize after this has been done.
The following message appears on the error display during this period:
