(DG) ST70 settings not saving

[[email protected]]

I have 5 ST70s as well as E80 chart plotter along with various other interconnected devices.
Recently one of the ST70s lost any customised settings and does not save any settings changes when powered off.
Is there an internal battery that needs replacing?

Hi [email protected]
Thank you for your enquiry.

Unfortunately it sounds like the ST70 in question has developed a fault, there is no back up battery inside and so the unit will need to be returned for investigation and possible repair.

The ST70 display should be sent to Raymarine’s Product Repair Center to be bench checked / serviced,please enclose contact details and as much description as possible to help the service engineer identify possible causes.
