TI-Nspire™ CX Handheld


With the built-in Press-to-Test feature on TI-Nspire™ handhelds, you can easily comply with the rules for the use of calculators in exams by temporarily disabling all current documents and denying access to programming libraries.

A blinking LED located at the top of the TI-Nspire™ handheld provides invigilators with a way to quickly and confidently see that a candidate's handheld is operating in Press-to-Test mode. After the exam, handhelds are easily restored for classroom use by exiting Press-to-Test mode and all previously created documents restored.

The new Press-to-Test feature is only available with TI-Nspire™ operating system version 1.3 or higher.

To start Press-to-Test mode:

  • Turn the TI-Nspire™ device OFF
  • Press and hold the ESC and HOME keys
  • While ESC and HOME are pressed and held, turn ON
  • Make selections and confirm Degree, Radian or Gradian (can be changed afterwards)
  • You will see that the "Limit geometry functions" box is selected by default. Deselect the box if you decide to allow all geometry functions.

Select OK. The handheld will restart and the Press-to-Test confirmation screen will appear.

Select OK. A blinking green LED on the handheld indicates the unit is in a Press-to-Test mode that restricts geometry features. A blinking yellow LED indicates the unit is in a Press-to-Test mode that restricts non-geometry features.
Note: Whilst in Press-to-Test mode, you can send and receive files. However, once you exit, all documents created while in Press-to-Test mode are deleted.

To end Press-to-Test mode:

Connect the device to another handheld or computer Navigate to My Documents.

On a TI-Nspire™ with Touchpad or CX handheld

  • Press and release DOC
  • Select 9 to exit Press-to-Test

On a Clickpad

  • Press and release CTRL
  • Press and release HOME
  • Select 9 to exit Press-to-Test

Note: Only a device connected to another handheld or computer can exit the Press-to-Test mode. Before you begin this process, you must have access to another TI-Nspire™ handheld with an operating system of 1.3 or higher.

To disable Press-to-Test mode through a computer:
If you choose to disable Press-to-Test mode through a computer, you must have TI-Nspire™ Computer Link software installed on your system. After installing TI-Nspire™ Computer Link:

  • Create a folder on your computer called “Press-to-Test”
  • In that folder, place an empty tns document called “Exit Test Mode”. This file is the only file that should be in that folder. Note: folder and file names are case-sensitive
  • Send this file to your connected device and you will exit Press-to-Test mode

The Press-to-Test feature also works with the TI-Nspire™ handheld's interchangeable TI-84 Plus Keypad. Programs and Apps not allowed during testing will be temporarily disabled and then restored after the exam.

When the TI-84 Plus Keypad is inserted, the Press-to-Test feature configures the TI-Nspire™ handheld just like TI-84 Plus and TI-84 Plus Silver Edition family graphing calculators. If using the TI-84 Plus keypad with a TI-Nspire™ handheld, please refer to TI TestGuard™ for similar functionality.
