Without taking action, the internal dates/clock will either roll-back to a previous incorrect date, and display the wrong position, or the units can be expected to fail.  The impact is compounded when interfacing with other navigation equipment (ECDIS, GMDSS, SSAS. VDR, ODME, etc.).

Mackay is standing by ready to provide software upgrade assistance or product replacement in order to maintain data integrity and reliable navigation operations.
