Welcome to

the

HP-22S

Your

HP-22S reflects the superior quality

and

attention to detail in

engineering

and

manufacturing that have distinguished Hewlett-

Packard products for more

than

years. Hewlett-Packard stands

behind this calculator: we offer expertise to

support

its use (see inside

the back cover), accessories,

and

worldwide service.

Hewlett-Packard Quality

Our

calculators are made to excel, to last,

and

easy to use.

• This calculator is designed to withstand the usual drops, vibrations,

pollutants (smog, ozone), temperature extremes,

and

humidity vari-

ations that it may encounter in normal, everyday use.

• The calculator

and

its manual have been designed

and

tested for

ease of use.

use spiral binding to let the manual stay open to

any page,

and

we include many examples to highlight the varied

uses of this calculator.

• Advanced materials

and

permanent, molded key-lettering provide a

long keyboard life

and

a positive feel to the keyboard.

• CMOS (low-power) electronics

and

the liquid-crystal display allow

the HP-22S to retain data while it is off,

and

let the batteries last a

long time.

• The microprocessor

has

been optimized for fast

and

reliable com-

putations. The calculator uses 15 digits internally for precise results.

• Extensive research has created a design that has minimized the ad-

verse effects of static

electricity-a

potential cause of malfunctions

and

data loss in calculators.

Welcome

the

HP·225

Features

The HP-22S's features reflect the needs

and

wishes we solicited from

customers:

• A 12-character, alphanumeric display that provides you with a va-

riety of

information-messages,

prompts, labels, and, of course,

numbers.

• Menus that greatly expand the number of functions available

and

make them easy to find.

• A broad range of numeric functions, including coordinate, base,

and

unit conversions.

• The IEVAL I

and

ISOLVE Ifunctions, which allow you to compute the

value of

any

variable in

equation.

• A library of built-in equations,

and

equation list that lets you

store your

own

equations.

• Statistical functions, including mean, standard deviation, weighted

mean,

and

linear regression

and

estimation.

• Twenty-six storage registers,

and

enough memory to store statistical

data

and

your

own

equations.
