Chapter 1: Getting Started with the TI-84 Plus C Silver Edition 37
Troubleshooting
If the recharge fails:
• Make sure the graphing calculator is seated properly in the slot. Batteries are not charged if the
connector on the graphing calculator and the connector in the slot are not aligned.
• Check the connector on the graphing calculator to ensure that it is clean. If there is build-up on the
graphing calculator’s connector, you can remove it with a clean, dry cloth or a pencil eraser. Never
use wet cloths or solutions of any kind.
Storing Charging Stations
Store the TI-84 Plus C Charging Station on a flat surface such as a table or a wheeled cart. You cannot
damage the charging station by leaving it plugged in for extended periods of time. Also, you cannot
damage the batteries by leaving them in the charging station beyond the time needed to fully charge
them.
Transferring the OS from calculator to calculator
You can transfer the operating system from one calculator to another using a USB unit-to-unit cable or
an I/O unit-to-unit cable (sold separately).
Note: You cannot transfer the OS or files using the TI-84 Plus C Charging Station. The TI-84 Plus C
Charging Station only charges the TI-84 Plus C graphing calculators.
Connect the two calculators by firmly inserting either the USB or I/O cable ends into the calculators. The
USB and I/O ports are located on the top edge of the calculator.
