HP -22S Owner's Manual page 3

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 40 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 to be 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. We 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.
