August 3, 2025 is JUST AROUND THE CORNER – GPS Rollover affecting JRC devices*:

JRC JHS-182 (AIS)
JRC NTE-182 (AIS Transponder)
JRC NTE-183 (AIS)
JRC NCM-983 (AIS)

JRC JLR-31 (GPS Compass)

In Case you missed it….. it’s not too late update these units if onboard:
September 8, 2024 GPS ROLLOVER impacted the following JRC devices*:

JRC JUE-500 (Inmarsat Fleet Broadband FB500)
JRC JLR-7500 (GPS Navigator)

JRC JLR-4331W (GPS Receiver)
JRC JLR-4340 (GPS Receiver)
JRC JLR-20 (GPS Compass)

*Depending on the device, either ALL or specific S/N or CORE may apply

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.

To coordinate service or product replacement, contact Mackay World Service 24/7 , any of Mackay’s 68+ Global Locations, or your regional Mackay Salesperson.
