Hi,
After more than 6 years in service I'd like to check if the button battery on the rtb2004 front board would need a replacement. No messages nor any problem arised by now.
The cell is easy to access once retired the back cover, but I'm not sure if removing it may delete any important record (like calibration or so) or it's just a RTC battery that in the worst case will reset the system date and time.
Of course the user manual doesn't even mention it.
Has anyone gone into this? Thanks!!
Alonso
