Sears, Roebuck And Co; Operation - Sears 10m Instruction Manual

INTRODUCTION
Your Sears Portable Electronic Calculator is light
enough and small enough to be used in one hand
yet it provides a standard keyboard and a light
emitting diode (LED) display that is easily read at
home or in the office.
The ten digit display and the full floating decimal
allow the calculation of most problems without
sacrificing accuracy, and the time-out feature
provides longer battery life between charges.
Your calculator has the ability to solve engineering
or bUdget problems, with such features as a
switch-selectable accumulative or fUlly accessible
memory, square root, reciprocal, percentage,
automatic constant, automatic squaring, and
change sign. The calculator operates In
"algebraic'" mode, which aflows you to perform
chain or mixed calculations in the order in which
they are written. The reciprocal and change sign
features are particularly helpfUl In solving complex
problems. We suggest that this programmed
Instruction Manual be read with the calculator in
hand. Performing the operations as you read them
will increase your familiarity with them. For a quick
reference, an outline of operations is on the back
of the calculator.
