Upgrading the Operating System
As new applications and
accessories are developed by Texas Instruments, operating system updates are
posted at their website. These new operating systems can be downloaded
from the website or transferred from one calculator to another.

Before you begin to update your OS, be sure you have a new set of
batteries in your TI handheld for optimum performance.
How do I quickly
upgrade the OS on students’ calculators?
Upgrading the Operating System
erases the RAM memory from the calculator. This means that any programs (games)
that reside under the “PRGM” button will be lost unless they are archived before
you begin. (Students generally will know how to archive.)
To archive: Go to
(2nd) MEM and choose #2 Mem
Mgmt/Del. Hit Enter. Arrow down to
#7 Prgm. Hit Enter.
Arrow down passed each PROGRAM hitting Enter as you
go. An asterisk will appear indicating that the program has been moved to
archive. If an asterisk is already present, this process will remove it (unarchive).
Be sure all programs have an asterisk before continuing. APPS are
automatically archived and will be safe.
To upgrade the OS: This is a simple
“send and receive” process. Connect the calculators and set your calculator to
“send” (LINK) and arrow down to
“G: SendOS”. Be patient! It is a
What if something goes wrong during the
transfer of an OS?
Most of the time, everything will be fine. There may be, however, that ONE
student who interrupts the transfer by fiddling with the calculator or whose
calculator simply is not cooperating. Don’t panic.
If you have a newer version of the
TI-Connect software (1.5.3 or higher), then simply do the following:
1. connect the calculator via cable to your computer
2. open TI-Connect software
3. choose TI Device Explorer
4. choose Tools
5. choose TI OS Download
6. remember where you store the new OS on your computer
7. be patient
If for some reason this process does not
work, try the process below:
