Miran Card loses calendar assigements

[lexer]

Hi, I've got two Miran cards NTAG37AB Version 2.0.17 (Rls 4), These Miran were storage for long time without use them, I'm testing these cards for a customer, I set the "calendar assigment", but Each time We poweroff or reset the PBX, the Miran card loses its assignments. The recorded messages are still there but the channel assignments need to be re-entered. Is there an on-board battery that retains these settings that I should replace?
Please any ideas?

Did you save the calendar assignment after you had made the changes?. The best way to check this is to navigate to the command line area where you can look at the files on the drive to see if the date has changed.
