5. Overflow condition
The following operations simulate the overflow condition and call t he overflow sign. In this
case, depress CE/C key for resetting .

Automatic constant calculation
Automatic constant calculation can be performed in all four rules and yX calculation.
After calculation is completed with
=
key being depressed, the function (+, -, x,
7,
or
yX) and the last operator number are automatically stored as a constant factor. Same
type of calculation can be continued by entering a new number and depressing the
corresponding function key or
=
key, as shown in sample calculations.
7. Automatic repeat calculations
Repeat calculations can be performed in all four rules and yX calculation by depressing =
key or function key continuously, as shown in sample calculations.
