It includes basic information about the many features available on the 10II+ along with example problems. If you require more information about the concepts 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 \, then >. To change the brightness of the display, hold down = and then simultaneously press 1 or A. shift key, 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). 2 Getting Started Figure 1 When you press \ or ], a shift annunciator or indicate that the shifted functions are active. For example, press is displayed to \ followed 2 to multiply a number in the display by itself. To turn the shift annunciators off, simply press \ or ] again. by In this guide, key symbols are used to indicate the key presses used in the example problems. These symbols vary in appearance according to whether they indicate 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: • • • 4 secondary function (display): \5 tertiary function (random): ]6 primary function (equals): Getting Started 3 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 operate differently. These special functions require subsequent key presses to operate. For example, the functions associated with the clear key, M, include: Table 1-2 Clearing functions Keys Associated Function M \N ]Oj ]OY ]OJ ]O: Clear display. Clear all memory. Clears bond memory. Clears break-even memory. Clears TVM memory. Clears cash flow memory.

There is a danger of explosion if batteries are incorrectly replaced. Replace only with the same type of battery or with equivalent batteries (as recommended by the manufacturer). Dispose of used batteries according to the manufacturer’s instructions. • The calculator is powered by two 3-volt CR2032 coin batteries. • When changing batteries, use only fresh coin-cell batteries. Do not use rechargeable batteries. • Do not mutilate, puncture, or dispose of batteries in fire. The batteries can burst or explode, releasing hazardous chemicals. • Do not use new and old batteries together, and do not mix batteries of different types. 1. Have two fresh CR2032 batteries at hand. Only touch the batteries by their edges. Wipe each battery with a lint-free cloth to remove dirt and oil. 2. Make sure the calculator is off. When changing the batteries, change the batteries one at a time to avoid clearing the memory. As a back-up, write down any data that you have stored and might need for later use. 3. Turn the calculator over and pry off the battery cover. 4. Gently remove one battery. Getting Started 33 5. Insert the new battery, making sure that the positive sign (+) battery is facing outward. 6. Gently remove the other battery. 7. Insert the other new battery, making sure that the positive sign (+) battery is facing outward. 8. Replace the battery-compartment lid. 9. Press 10. If the calculator does not turn on, follow the procedures in the section titled, Determining if the Calculator Requires Service in Appendix A of the HP 10bII+ Financial Calculator User’s Guide. =.
