Solution 14860: TI TestGuard™ 2.0 App May Not Set the Degree Angle Mode Setting on the TI-83 Family, TI-84 Plus Family, or TI-Nspire™ Handheld in TI-84 Plus Mode.
Why doesn't the TI TestGuard 2.0 app put my student's TI-83 family, TI-84 Plus family, or TI-Nspire handheld in TI-84 Plus mode into the degree angle mode setting?
The TI TestGuard 2.0 app changes the angle mode setting of student's units to Degree mode regardless of the version of the current OS (operating system) installed on the calculator. However, if the student presses any keys while the 'Transfer Complete' screen is displayed on the receiving calculator, TI TestGuard 2.0 will fail to change the mode settings. To ensure that TI TestGuard completes the setup properly, wait until the home screen (blank screen with blinking cursor) appears on the receiving calculator before pressing any keys.
For more information on using TestGuard 2.0, please see the TI TestGuard guidebook.
