Good day
I am lucky enough to have two cx's
Can anyone explain to me the difference between my two model versions?
When I remove the battery pack one says REV.D4 and the other says REV.C
... to correct myself, it is written into foil strip on the calculators battery terminals (not on the battery at all)
