| Notes: |
This is an 8-digit calculator with the
square root function √x and the
X2 key to square numbers. It has
separate fluorescent tubes for all eight digits. Above the display there are three leds. One
to indicate overflow, one to indicate low battery and one to indicate negative
numbers.
The slider on the left enables constant calculations, where repeatedly pressing the += or −= key repeats the last multiplication or division. Repeatedly pressing the −= key changes the sign with each operation. Very similar in design to the realtone micro EXECUTIVE Model 8414 The battery compartment is made in such a way that it can be removed after sliding a lever. After changing the batteries, click it back into place. |
