[. . . ] Please remove some documents first. " is displayed on the handheld. To restore memory, you must remove some of the documents before you can enter Press-to-Test mode. To resolve this condition: • • Delete unnecessary documents from your handheld Use TI-Nspire™ software to back up documents to a computer or another handheld. You can restore the documents after you exit Press-to-Test mode. Turning the handheld off and on in Press-to-Test mode If you turn off the handheld or if it goes into Automatic Power Down™ (APD™) while in the Press-to-Test mode, it remains in testing mode when powered on again. A message reminds you that the handheld is in Pressto-Test mode and shows the selected restrictions. Note: If a dialog is open when the handheld powers down while in Pressto-Test mode, that dialog is displayed when you turn the handheld on again. Clearing and re-entering Press-to-Test mode When a handheld is in Press-to-Test mode, you can clear data added in a previous session without exiting Press-to-Test mode. (On a Clickpad: press / w. ) 6 Using Press-to-Test 2. Press d c to turn the handheld on. (On a Clickpad: press dc w) The Press-to-Test window is displayed. 3. Click Reset Press-to-Test to clear the data. 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 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. When a student manually enters the log(a, b) and >logbase(, commands, submitting the command results in an error message. Students are allowed to enter log(a), log(a, 10), and log(a, 10. ).

To exit Press-to-Test mode, the handheld must be connected to another TI-Nspire™ handheld, TI-Nspire™ CAS handheld, TI-Nspire™ CX handheld, or TI-Nspire™ CAS CX handheld. [. . . ] This menu option is visible and active only while in Press-to-Test mode. c) 5. Press ¢ and select Exit Press-to-Test. If a class is not active, the message "Connect your TI-Nspire™ Handheld to another TI-Nspire™ Handheld and try again" is displayed. Using Press-to-Test 19 Returning from Press-to-Test to normal functionality Exiting Press-to-Test clears all data and files created while in Press-to-Test mode. All files and system settings are restored to what they were before Press-to-Test was enabled on the handheld. • All documents created during the Press-to-Test session are permanantly deleted.
