HP -01 Owner's Manual page 8

Introduction
Time: elusive and immediate...limited yet infinite. Because time is important to you, Hewlett-
Packard introduces the HP-01, a new dimension in time management and personal computa-
tion.
It's a digital electronic wristwatch, a personal calculator, an alarm clock, a stopwatch, a timer, a
200-year calendar...and yet it is more than all of these. The HP-01 is a unique, interactive
combination of time and computation functions that offers unmatched capability and versatility.
You can do anything from viewing the time to dynamically calculating the cost of a long-
distance phone call or,if a pilot, finding the distance to your next checkpoint.
For years, Hewlett-Packard atomic clocks have been used by international observatories and
authorities to set time standards with accuracy to within one second in over 3000 years.
Currently, millions of HP pocketcalculators are in use throughout the world. The same company
with this proven and respected clock and calculator expertise stands behind your HP-01.
Hewlett-Packard congratulates you on the acquisition ofthis fine instrument. We hope you will
wear and use it with the same pride that its creators at HP take in this remarkable technical
achievement.
