In the overwriting mode, the sign before the cursor “ _ “ will be deleted by
pressing [DEL] or directly replaced by inserting a new character.
To delete all characters, press [AC] .
Error indication function (Error)
If an illogical or unrealizable mathematical operation is to be performed, the
function indicates an error and its location. Find the error by pressing [◄] or
[►] and correct it before repeating calculation.
Replay
The function saves the last performed operations in the COMP mode. By
pressing [▼] or [▲] after the last calculation you can view the last performed

Memory-based calculations
The calculator has 9 different memories available for repeated use: A, B, C, D,
E, F, M, X, Y. A real number can be saved in any of the 9 memories.
• [2ND][STO] + [A] to [F] , [M] , or [X] or [Y] enables saving the value into
a given variable.
• [RCL] + [A] to [F] , [M] , or [X] to [Y] recalls the saved values from the variables.
•
[0][2ND][STO]
+
[A]
to
[F]
,
[M]
, or
[X]
to
[Y]
deletes content of a selected
variable.
• [ALPHA] + “variable in memory” enables entering a respective variable
in the calculation.
