The F↔E key also converts the display format of a displayed numerical value simultaneously with the display format setting. At the same time, the number of digits below the decimal point of the above modes follows the display format assigned by the 2dnF and F↔E keys. Further, in the same manner as the F↔E key, the conversion is also takes place simultaneously with the display format setting. When the number of digits is specified, the last digit displayed is a rounded number, and when there is no specification of the number of digits, the last digit displayed is a cut number.

In setting data in the mantissa section, this key reverses the code in the mantissa section. Similarly, for the exponent section, it reverses the code in the exponent section. b. For the operation result, this key reverse codes in the mantissa section. (6) + - X ÷ = ( ) a. When the key operation are performed by these keys according to a numerical expression, a result of the operation is obtained according to mathematical priorities. Priorities discriminated are: 1) 1 Variable function 2) Expression in ( ); (The most inner expression has priority in case of multiple parentheses) 3) yx, x y 4) x, ÷ 5) +, b. Whenever the key is operated, the calculator discriminates the above priorities and holds the data and operation keys pending as required. This pending action is possible up to 6 times and 7 or more pending become error. c. (Key is accepted only immediately after CE, +, -, ×, ÷, y cases. When this key is accepted, the displayed data is cleared to 0. When ( key is first accepted, the special display “ )”illuminates. ( When a parenthesis expression is completed) and = keys or when it is cleared by the ON/C key, etc, or when errors are generated, the special display “ )”goes out. ( d. If it is within the allowable range of pending, (can be input into any place in an expression as many times as desired. However, if the key is pressed continuously 16 times or more, it be comes error. e. From a viewpoint of numerical expression, even when the corresponding C key is not pressed, the operation is not executed if the “ key is pressed. On the other hand, when the “ key is pressed and the “ key is )” (“ =” pressed without pressing the corresponding “ key, the operation is also completed according to the priority. )” 7.

All of our MOS devices are internally protected against electrostatic discharge but they can be damaged if the following precautions are not taken: • Persons at a work bench should be earthed via a wrist strap. • Equipment cases should be earthed. • All tools used during assembly, including soldering tools and solder baths, must be earthed. • MOS devices should be packed for dispatch in antistatic/conductive containers.
