INTRODUCTION

Sharp's amazing CS.22C electronic desk calculator using lCs (lntegrated Circuits) marks

another major advance in modern business methods. Years of pioneering research and

resourcefulness in electronic engineering has enabled Sharp to develop an exceptionally

remarkable desk calculator with a memory register.

The CS-22C is thoroughly reliable and carries out complicated calculations with amazing

speed and efficiency. This booklet has been prepared to give current users and prospec-

tive buyers a detailed understanding of the scope and breadth of the machine's operation.

FEATURES

* Superior MOS-lCs

83 M0S-lcs( Metal 0xide Semiconductor lntegrated Circuits), 75 transistors and 34g

diodes drastically reduce the number of working parts, increase dependability.

* Memory register

Stores intermediate answers f or continued calculation. . . . enables extremely complicat.

ed and diverse calculations, such as sum of procucts, calculations by constant, etc.

* Compact

ïhanks to 83 lcs, the cs-22c is amazingly compact and light.

* Round off device

setting the Round off diar convenienily counts fractions over 1 /z as one, rounds off

othe rs.

*Overflow error check lamp

When the results of multiplication and calculation by memory exceeds I4 digits,

the red Error lamp turns on.

* Memory indicator

when the memory entry is registered, the red Memory ramp turns on.

* Double-set protection keys

Eliminate error, speed up operation...no more worry about doublesetting keys.

* CIear display panel

Snap reading with advanced electronic numerical indicators. The provided hood pre-

vents annoying glares caused by light refrecting off the dispray paner

x Simplifíed exponent calculation

{< Optional ' Memorizer "

Sharp's dial unit Menorrzer 10 CSA-10 or automatic prograrner ,Memorizer 30

& 60" CSA- i 1 & 12 can be easily connected for simplified diverse calculation by

cons tant.

* Sophisticated space-age styling

Lightweight and noiseless, easy-to-carry the cs-22c enhances modern office decors,

upgrades working areas, increases efficiency.
