Hewlett-Packard Quality
Our calculators are made to excel and to be easy to use.
This calculator is designed to withstand the drops, vibrations,
pollutants (smog, ozone), temperature extremes, and humidity
variations that it may encounter in everyday work life.
"The calculator and its manual have been designed and tested for ease
of use. We added many examples to highlight the varied uses of the
calculator.
Low-power electronics and an advanced power management system
gives extended battery life.
The microprocessor has been optimized for fast and reliable
computations using 15 digits internally for precise results.
Extensive research has created a design that has minimized the
adverse effects of static electricity, a potential cause of malfunctions
and data loss in calculators.
