E4 -

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 15 levels or

more pending become error.

c. [ ( ] key is accepted only immediately after [CE], [+], [

−

], [x], [

], [

], [=], [ ( ] keys can not accepted in all other 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 [=] key 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
becomes error.

From a viewpoint of numerical expression when the
corresponding “ ) ” key is not pressed, the operation is not
executed even if the “ ( ” key is pressed. On the other hand,
When the “ ( ” key is pressed and the “ = ” key is the pressed
without pressing the corresponding “ ) ” key, the operation is
also completed according to the priority.

a. The memory register “M” used by these keys is a completely

independent single memory.

b. Display data is added to “M” (memory register) by [M+] key. If

data overflows at this time, the proceeding data is hold.

c. Display data is stored in “M” by [X

M] key.

d. Contents of “M” is displayed by [MR] key.

e. When any data except for 0 is stored in “M”, the special display

“M” illuminates.
