HOW TO CONNECT THE AC ADAPTOR (OPTION)

This machine can also be operated on AC power by use of AC Adaptor. When the AC adaptor is connected to the calculator, the power source is automatically switched over from dry batteries to AC power source.

AC adaptor: Model EA-28A (Never use any other AC adaptor except EA-28A.)

Note: Make sure that you turn the calculator ’s power off when connecting or disconnecting the AC adaptor.

To connect the AC adaptor, follow

steps and .

To disconnect the AC adaptor, simply reverse the procedure.

CAUTION

Use of other than the AC adaptor EA-28A may apply improper voltage to your SHARP calculator and will cause damage.

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.

If “0 • E” is displayed at the time of the error, “– – – – – – –” will be printed in red and C CE must be used to clear the calculator.

Error conditions:

1.When the integer portion of an answer exceeds 12 digits.

2.When the integer portion of the contents of the memory exceeds 12 digits. (Ex. M 999999999999 M+ 1 M+ )

3.When any number is divided by zero. (Ex. 5 0 ).
