Transferring Programs to Your Calculator

To transfer programs from your computer to your calculator, you need a cable to connect the two, which was likely included with your purchase. For some models, this is a simple USB-to-miniUSB cable that is commonly used with many other devices. A guide to connect your calculator and install the required software is available here. After you have completed this step, you can copy downloaded programs to your calculator using these instructions.
