Happy user of the Promark 500 here, however, recently when I go to set up the base station to log over a single point for the day the file dates come back saying the year is 1999 (it is currently 2019).
I've double checked the date and time is correct on the handheld and I've tried getting to the logging stage a couple of different ways with no improvement.
Any ideas? or ways to reset the system or correct the date and time on the base station? could it be an internal battery has died?
