software, such as the CellSheet App, that can be installed and run on a
TI handheld.

Important — Read This Before You Begin

• Upgrading the OS erases everything in random-access
memory (RAM). You may want to perform a backup using

TI Connect or TI-GRAPH LINK software before upgrading the
OS.

• New batteries should be installed in the TI handheld before
beginning an OS upgrade. Do not attempt to upgrade OS or install

an App if a low battery message appears on your TI handheld.

• Do not remove the TI-GRAPH LINK cable from either the
computer or the TI handheld during an OS upgrade or App
installation. Never interrupt an OS upgrade or App installation.

Choose the instructions for your software and computer type.
