When in OS download mode, the Automatic Power Down™ (APD™) feature
does not function. If you leave your handheld in download mode for an
extended time before you begin the downloading process, your batteries may
become depleted. You will then need to replace or recharge the batteries
before downloading the OS.

You can download an OS upgrade from the Texas Instruments website to a

You will need an Internet connection and the appropriate USB cable to
download the updates.

your computer.
2. In the Documents Workspace, click to open Content Explorer.
