Getting Started
This guide is intended to get you started with your new 10bII+ financial calcula-
tor. It includes basic information about the many features available on the 10II+
along with example problems. If you require more information about the con-
cepts presented here, refer to the HP 10bII+ Financial Calculator User’s Guide on
the CD included in the package along with your calculator. For more information
about HP calculators, please refer to the training materials available at:
www.hp.com/calculators.
Power On and Off
To turn on your HP 10bII+, press =. To turn the calculator off, press the orange
shift key, \, then >. To change the brightness of the display, hold down
=and then simultaneously press 1or A.
Since the calculator has continuous memory, turning it off does not affect the
information you have stored. To conserve energy, the calculator turns itself off
after five minutes of inactivity. The calculator uses two CR2032 coin batteries. If
you see the low-battery symbol ()in the display, replace the batteries.
See the section below titled, Replacing the Batteries for more information.

Shift Keys
Most keys on the HP 10bII+ have three functions:
• a primary function printed in white on the key.
• a secondary function printed in orange on the bevel of the key.
• a tertiary function printed in blue above the key on the keyboard (see
Figure 1).

When you press \or ], a shift annunciator or is displayed to
indicate that the shifted functions are active. For example, press \followed
by 2to multiply a number in the display by itself. To turn the shift annuncia-
tors off, simply press \or ]again.
In this guide, key symbols are used to indicate the key presses used in the exam-
ple problems. These symbols vary in appearance according to whether they indi-
cate the primary, secondary, or tertiary functions required for the problem. For
example, the functions associated with the equals key, 4, are illustrated in the
text as follows:
• primary function (equals): 4
• secondary function (display): \5
• tertiary function (random): ]6

4 Getting Started
Boxed Key Functions
There are three shifted key functions on the calculator that are used to change the
operation of another key's function. These three tertiary functions, ]O,
]o and ]r, are bound by blue boxes to show that they oper-
ate differently. These special functions require subsequent key presses to operate.
For example, the functions associated with the clear key, M, include:
