3.5 ERROR AND WARNING CODES
A number of situations can occur which either prevent calculation of the position or can lead to
misrepresentation of the data.
If calculations cannot be performed on the data received, a message is displayed in the Status
Block and an ERROR CODE is sent out on the RS-232.
Other error codes that are displayed on the status line and sent out on RS-232 are warnings.
