Teach, please.
Does the memory of my HP-41CV break?
I have HP-41CV and HP-41CX.
#1 I push a "[<-] + [on]" key at the same time.
#2 A calculator indicates "MEMORY LOST".
#3 I push a [PROG] key.
#4 "HP-41CX" is indicated with "00 REG 219".
#5 "HP-41CV" is indicated with "00 REG 46".
I don't know why the indication of "HP-41CX" and "HP-41CV" is different.
Does the memory of "HP-41CV" break?
Or, is the default value of "HP-41CX" and "HP-41CV" only just different, and may I be relieved?
