ERRORS

There are several situations which will cause an overflow or an error condition. When this occurs, E will be displayed. The contents of the memory at the time of the error are retained. must be used to If an 0E is displayed at the time of the error, will be printed in red and clear the calculator. Also, in rare cases, printing may stop midway and the indication E appear on the display. This is not a malfunction but is caused when the calculator is exposed to strong electromagnetic noise or static electricity key and then repeat the calculation from the from an external source. Should this occur, press the beginning. Error conditions: 1. When the integer portion of an answer exceeds 12 digits. 2.
