FEATURES
*
Full
y Integrated Circuit (lC)
Advanced MOS-MSls (Metal Oxide Semi-conductor Middle Scale Integrations and
MOS-ICs (Metal Oxide Semi-conductor I ntegrated Circuits) enormously reduce the
amount of working parts and ensure greater dependability through superior trouble
free performance.
*
Compact
and
easy
to
carry
Space-age all IC design and unique memory device make the CS-221A amazingly
compact and light; can be carried anywhere with utmost ease and convenience.
*
Wide
ra
nge of calculations
I n addition to its four arithmetical operations, mUltiplication, division by constant,
discount calculation and memory calculation can be quickly carried out with maxi
mum efficiency.
*
Ease of operation
Simplified operations such as AxBxCx ...
=,
A.-;-B.-;-C ...
=
etc. require no special
training. The answer to almost any practical mathematical problem appears instantly;
*
Easy
to
read
display panel
Snap reading with newly developed green numeral indicator.
Does
not cause eye
strain with long use.
*
Automatic decimal positioning
Tabulation selector specifies the decimal positioning automatically.
*
M
inus sign indicator
Automatically turns on when the result is negative.
*
Overflow error check system
When the result of calculation exceeds 12 digits, all the decimal points automatically
turn on and calculation function stops.
No worry about mistake by
overflow.
*
Double-setting protection keys
Numeral keys are so designed that no two keys are set at a time. This eliminates
error, speeds up operation .
