|Batteries:||C x 4|
Huge and heavy desktop calculator. It needs four big "C" type
batteries to operate without the power supply! The keys are big
and heavy duty, and the green fluorescent display has 8 digits and
a special "SIGN" digit. This last one is really special. The table
below shows how it works:
Also present are a switch to turn constant operations on and off, and a switch to set the calculator's accuracy.
Another special feature is the soft ON/OFF by means of two buttons instead of a switch.
Also take a look at this calculator's brother, the Soundesign 8301.
