# HP 12c Platinum Manual

This HP 12c Platinum (can use a reference for HP 12c) Owner’s Handbook and Problem-Solving Guide is intended to help you get the most out of your investment in your HP 12c Programmable Financial Calculator. Although the excitement of acquiring this powerful financial tool may prompt you to set this handbook aside and immediately begin pressing buttons, in the long run you’ll profit by reading through this handbook and working through the examples it contains. The handbook is organized basically into three parts:

Part I describes how to use the various financial, mathematics, statistics, and other functions (except for programming) provided in the calculator.

Part II describe how to use the powerful programming capabilities of the HP 12C Platinum.

Part III give you step-by-step solutions to specialized problems in real estate, lending, savings, investment analysis, and bonds. Some of these solutions can be done manually, while others involve running a program. Since the programmed solutions are both selfcontained and step-by-step, you can easily employ them even if you don’t care to learn how to create your own programs. But if you do start to create your own programs, look over the programs used in the solutions: they contain examples of good programming techniques and practices.

Press [f] and next [CHS], or going by correct functions [f],[RPN]. If that doesn't work, the keyboard is busted.

Your 12c Platinum was probably built before 2006.
