The miniDose unit which is unable to communicate the data could be due to corrupted software. All else are working fine except for the data which is not reflecting on the software.
As this was manufacture to be an inexpensive radiation unit, no software reflash or replacement parts are available.
Factory has checked that the warranty for the unit has expired since Feb 2016 and thus warranty is not covered.
Please recommend user a replacement unit.
