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.
Finding operating system upgrades
For up-to-date information about available OS upgrades, check the Texas
Instruments web site at http://education.ti.com.
You can download an OS upgrade from the Texas Instruments web site to
a computer, and use a USB cable to install the OS on your TI-Nspire™
handheld. You will need an Internet connection and the appropriate USB
cable to download the updates.
