[3] LAT/LON Correction
This method corrects a chart position by changing the values of latitude and longitude that are sent by

Only our service engineers are to use this correction method because the contents of data such as
track data to be saved are changed when the method is used.
A correction value can be entered in the range -9.999' to +9.999'.
