[. . . ] (On a Clickpad: press dc w) The Press-to-Test window is displayed. 3. Click Reset Press-to-Test to clear the data. To retain the data from the previous session, click OK. Selecting Reset Press-to-Test retains all restrictions and clears all documents created and data entered in the previous Press-to-Test session. Note: If you have entered and saved data on the handheld in TI-84 mode, that data is not deleted if the handheld is cleared in Press-to-Test mode using a TI-Nspire™ keypad. However, the TI-84 Plus data is not accessible when using the TI-Nspire™ keypad. Auto-save If the handheld re-boots while in Press-to-Test mode, the handheld remains in testing mode and returns to the last opened document. Managing battery power If using a TI-Nspire™ or TI-Nspire™ CAS handheld, you can remove and replace batteries while in Press-to-Test mode. If you change the batteries, the handheld remains in testing mode. When you turn it on again, the reminder dialog is displayed. If using the TI-Nspire™ CX and TI-Nspire™ CX CAS handhelds, you should ensure the rechargeable battery is fully charged before launching Pressto-Test mode or before beginning an exam. Switching keypads The TI-Nspire™ CX and TI-Nspire™ CX CAS handhelds have fixed keypads. You cannot switch to a different keypad if using a TI-Nspire™ CX handheld. Using Press-to-Test 7 When using the TI-Nspire™ or TI-Nspire™ CAS handheld, be sure to exit Press-to-Test mode before attempting to switch to a different keypad; for example, from a TI-Nspire™ keypad to a TI-84 Plus keypad and vice versa. If you switch keypads while in Press-to-Test mode, the handheld displays the following message: Working with documents in Press-to-Test mode When the handheld is in Press-to-Test mode, all folders and documents present on the handheld before you entered Press-to-Test mode are disabled. While in Press-to-Test mode, you will only see the Press-to-Test folder listed in My Documents. Teachers can send and collect documents when handhelds are in Press-toTest mode. Students are allowed to enter log(a), log(a, 10), and log(a, 10. ). Disabling summation functions and templates Students are prevented from using commands, , and templates related to summation.

[. . . ] The information in this section only applies to TI-Nspire™ when using the TI-84 keypad. Enabling Press-to-Test mode 1. Press and hold |, ~ and É until the Reset Options screen opens. By default, the angle mode is set to DEGREE, Stat Diagnostics are ON, and the functions logBASE and summation (∑) are disabled. To change the default settings, move the cursor over the desired setting and press ÎÍ. Press q (beneath OK on the screen) to select OK. [. . . ]
