• Delete selected data stored on students’ calculators before tests.
• Disable selected data on student’s calculator before tests, including
an option for all programs and selected applications.
Important! Be sure to follow the recommendations listed in the
section Before Using TI TestGuard™ 4.0.
• Restore previously disabled programs and applications on student
calculators after tests (if needed).
TI TestGuard™ 4.0 Requirements
The TI TestGuard™ application is not publicly available. To request
TI TestGuard™, call 1-800 TI-Cares.
Important! You must first install TI Connect™ on your computer before
you can install TI TestGuard™ 4.0 on your educator calculator. For
instructions on installing TI Connect™ go to education.ti.com/software.
Hardware Requirements
• TI-83 Plus, TI-84 Plus, and TI-84 Plus C Silver Edition calculators.
• TI USB Connectivity Cable for Windows®/Mac® – to transfer
TI TestGuard™ 4.0 from your computer to your calculator.
• I/O (Input/Output) unit-to-unit cable – to transfer the calculator
setup to a student’s calculator.
Note: TI TestGuard™ 4.0 does not run on the TI-84 Plus mode of the
TI-Nspire™ handheld software.
Software Requirements
• 1500 bytes of free RAM on your calculator.
• For TI-83 Plus calculators – OS version 1.19.
• For TI-84 Plus calculators – OS version 2.55MP.
• For TI-84 Plus C calculators- OS version 4.0.

2 Before Using TI TestGuard™ 4.0
Before Using TI TestGuard™ 4.0
Before you use TI TestGuard™ 4.0, consider the following
recommendations:
• Ensure that you are using the correct operating system on your
calculator. TI TestGuard™ 4.0 application functions with OS version
1.19 for TI-83 Plus, 2.55 MP for TI-84 Plus, and 4.0 for TI-84 Plus C
Silver Edition calculators.
• Advise students to install the latest operating system before an
exam.
• Advise students that TI TestGuard™ 4.0 deletes all programs and
applications on a TI-83 Plus calculator. Students must backup and
re-load programs and applications on the calculator using
TI Connect™ or by linking to another calculator.
•The
Disable logBASE and summation S( functions feature works
on a TI-84 Plus with OS version 2.55 MP and the TI-84 Plus C with OS
version 4.0.
–logBASE and summation S(functions are unavailable for TI-84
Plus with OS version 2.43 MP or earlier, and the TI-83 Plus. If you
create a calculator setup to disable these functions and then
transfer this setup to one of these calculators, TI TestGuard™ 4.0
ignores the DISABLE FUNC setting and no error is created.
– An attempt to disable logBASE and summation S(functions
for the TI-84 Plus with OS version 2.53MP displays an error
message. You must upgrade the OS to 2.55 MP and then transfer
the calculator setup.
• Ensure that the student handheld has 2500 bytes of free RAM.
Note: If the student’s calculator does not have enough free RAM,
TI TestGuard™ 4.0 displays a memory error. In that case, you must
manually remove RAM data from the student’s calculator before you
can run TI TestGuard™ 4.0.
• Ensure you are in possession of both your educator calculator and
the student’s calculator when transferring the calculator setup.
– Ensure the student’s calculator is on the Home screen.

DELETE Mode
Deletes data and applications on a student’s calculator:
Note:
• If you select APPS as the DELETE mode setting and also disable the
logBASE and/or summation S( function, TI TestGuard™ 4.0
changes the mode setting to ALL, so programs are also deleted.
Programs must be deleted to prevent the retention of the pre-
