Texas Instruments TI-84 Plus Series Guide Book

Using Press-to-Test
As an alternative to TI TestGuard™, Press-to-Test deletes all RAM and Archive
and disables Programs, Apps, Pic Vars, and Image Vars.
You can access Press-to-Test on TI-84 Plus calculators with OS versions 2.40,
2.43, 2.53MP and 2.55MP, and the TI-84 PlusC with OS version 4.0 and
higher.
Note: Press-to-Test includes fewer calculator options on TI-84 Plus with OS
version 2.40, 2.43, and 2.53MP.
To use Press-to-Test on a student’s calculator, complete the following steps:
1. With the TI-84 Plus or TI-84 PlusC turned OFF, press and hold down the
right, left, and ON keys, and then release.
2. The RESET OPTIONS screen displays:
TI-84 Plus C
Notes:
• A blue status bar is shown on the TI-84 Plus C when in TEST MODE
and TEST MODE ENABLED.
• Pic & Image Vars are disabled on the TI-84 PlusC. These Vars are
stored in Arc memory on the TI-84 Plus C. Vars are deleted from RAM
and Arc on the TI-84 Plus and TI-83 Plus.
• By default, ANGLE is set to DEGREE, STAT DIAGNOSTICS is set to
ON, and DISABLE logBASE and DISABLE S( are set to YES.
