Note: You can transfer any file, not just the OS, to the calculator using this method.

Verifying memory space

Before installing TI-Navigator applications, you must verify that you have enough free memory space on your TI-73 Explorer. Applications on the device take up blocks of memory called "application slots. The bigger the application, the more slots it will require. The TI-Navigator applications (LearnChk, NavNet, AlgACS, navstk) require a total of five application slots. The TI-73 Explorer has a total of eight application slots. 1. On your calculator, press [-. The memory screen opens.

Select 3: Check APPs.

The calculator displays how many slots are free, and how many slots each of the existing apps require.
If there are five or more free slots, proceed to the steps for transferring applications to your calculator. If there are fewer than five free slots, you must remove applications from your calculator to make space for the required TI-Navigator applications. You can save the applications you remove to your computer, or delete them.

Frequently-asked questions
What is different when using TI-Navigator with the TI-73 Explorer?
The TI-73 Explorer can perform all of the same TI-Navigator functions as the TI-84 Plus with the following exceptions.

Activity Center notes

In Activity Center, The TI-73 Explorer can submit four equations at a time, not ten. The functions available on the TI-84 Plus versus the TI-73 Explorer differ slightly. Functions that are available in Activity Center on the TI-73 Explorer include: sin( cos( tan( Arcsin( Arccos( sqrt( abs( int( ln( exp( log( rand PI
LearningCheck Creator and Class Analysis notes
Can I use LearningCheck documents created for the TI-83 Plus or TI-84 Plus? You can use any existing LearningCheck Creator.edc files with the TI-Navigator 2.2 software. There are, however, some exceptions when using LearningCheck Creator and Class Analysis with the TI-73 Explorer. These exceptions are noted below: Send to Device does not work in LearningCheck Creator (use Send to Class). To enter text, you must press - t menu on the TI-73 Explorer. The TI-73 Explorer does not support the TI keyboard. Student answers are saved in an answer file. When this answer file is collected directly from the calculator to the computer, it has a.73v extension. However, Class Analysis will only load.8xv files. When you collect an answer file from students, TI-Navigator handles the class type discrepancy by saving two versions of the students answers on the computer. One will have a.73v extension (which can be returned to a device) and one will have a.8xv extension (which can be used in Class Analysis). If you collect an answer file outside of TI-Navigator through other tools such as TI Connect, you collect only a.73v file as expected. However, you will not be able to analyze these files in Class Analysis. All text entered on the TI-73 Explorer is upper case. If you create questions that require a case-sensitive answer, correct answers may be marked incorrect. All characters in LearningCheck Creator's character palette and all characters on a standard computer keyboard will display on TI-73 Explorer in question text, section text and fill-in-the-blanks pull down. Fill-in-the-blank text supports a limited character set. You should be careful not to create a question requiring a correct answer that is impossible to create on the device. From the computer keyboard, the following characters are NOT available on the TI-73 Explorer: | (vertical pipe) ` (accent mark) \ (backward slash) ~ (tilde)

@#$& _ (underscore) ; (semi colon)
On the character palette provided by LearningCheck Creator, these are the ONLY characters also available on the TI-73 Explorer:
Why do I get a Communication Failure sometimes even though I am plugged in? If you get a failure to communicate on the calculator, it probably means that two things were trying to happen at once. For example, if you take a screen capture while someone is logging in, you may have to refresh screenshots. Simply retry on the calculator or computer. Why do some of my students miss a Force to Students? If the teacher forces a transfer and the calculator does not automatically receive the file, the file is still there waiting for the student. From the TINavigator Home screen on the NavNet App, the calculator user simply selects 3. TRANSFERS 1. AUTO SEND/RECV to request any files waiting for them. How do I do things off the network during a class session? If the calculator user is going to disconnect from the network (example: to do a CBR collection), the calculator user will need to exit NavNet before disconnecting. Not doing so will not harm the system but the user may have to login again when accessing NavNet.
Can I use TI-Navigator without the Access Points and Hubs? You can use the system with a calculator connected to the computer through the USB Silver Edition cable. This is great for trying out lessons when you are lesson planning without having the network set up. Why do I get errors in TI Connect when I have TI-Navigator open? You cannot use the USB Silver Edition cable with TI Connect software and TI-Navigator software at the same time. If you want to use TI Connect software to communicate with a calculator, TI-Navigator software must be closed. How many apps slots will TI-Navigator require? The TI-73 Explorer has eight available app slots. The TI-Navigator apps will take three of these, while LearningCheck will take an additional 2. This leaves three app slots for other applications. For example, you can fit NumberLine, Geoboard, and the CBL/CBR app in addition to the TI-Navigator applications. Can you have a mixed classroom of TI-73s and TI-83s or TI-84s? No, you need to assign each class a device type. This can either be the TI-73 Explorer or a mixed classroom of TI-83 Plus and TI-84 Pluses. Can I change the device that my class uses? No. The best way to enable a class to use a different device is to create a new class, and then copy and paste the students from the original class to the new class of a different calculator family. This will result in two identical classes -- one for the TI-73 Explorer Classroom and one for the TI-83 Plus/TI-84 Plus Classroom. Will TI-Navigator require an OS update? The TI-73 Explorer requires an OS update to run TI-Navigator. The new version is 1.80. If you do not have this version, you can download it from the TI-Navigator 2.2 CD to the TI-73 Explorer with the TI Connect software. Will the TI-Navigator functions in TI InterActive! software work with the TI-73 Explorer ? No. TI InterActive! software was not designed to work with the TI-73 Explorer.
