Linking and Troubleshooting Internet address information The main internet address for Texas Instruments is http://www.ti.com/ The calculator materials main menu can be obtained at http://www.ti.corn!calc/docs/ It is unlikely the above two entry addresses will change. Web page designs do change, but the following addresses are current as of 1 January 1 1998 and will probably remain stable for finding the following topics.

But we include the following tips. »- The end-jack must be pushed firmly into the socket. There is a final click you can feel as it makes the proper connection- »- If you are experiencing difficulty connecting, turn off both calculators, check the connection, and then turn them on and try again. If available, try other cables or calculators. »- When selecting items, the cursor square is hardly visible when the selection arrow is on the same item. As you arrow off of the item, double-check whether or not it has been selected. »- If you are required to drain your calculator memory before entering an exam, use Back UP to keep a copy on some other calculator. Even better is to store it on your computer, which is the next topic. Linking to a computer The TI-Graph LinkTM is a cable and software that connects to a PC or Macintosh computer and your TI calculator. The software is available on the internet, so you can order only the cable. There are many advantages to using TI-Graph LinkTM. .This is the best way to back up your work. It is the preferred way to write and edit programs. You can download and transfer programs from the internet archives- It allows you to capture the screen in a form for direct printing or use in a word processor Troubleshooting Nothing shows on the screen. Check the contrast. Check ON/OFF button. Pullout the batteries and correctly reinsert the batteries. As a last resort, remove the backup battery and reinsert all the batteries. Warning: This will erase all memory, including programs. Nothing shows up on the graph screen except the axes. Press TRACE to see if a function is defined but outside the window. There may be no functions selected. The function may be graphed along either axis and need the window reset. .If there is a busy indicator (a running line) in the upper right comer of the screen, then the TI may be still calculating. Press ON if you can't wait. If there is a pause indicator (twinkling line) in the upper right comer of the screen, then the TI is paused from a program. Press ENTER to continue. If there is a full checkerboard cursor, then you have a full memory. You need to delete something; choose some things you no longer need or copy them to your computer. Nothing shows up in the table You may have the Ask mode set and need to either enter x-values or change to Auto in the 2nd-TBLSET . Check to see that a function is selected. I get a syntax error screen The most common errors are Parenthesis mismatch. Count and match parentheses carefully. Subtraction vs. negative symbol. For example, the subtraction sign cannot be used to enter -10. Pasting a command in the wrong place. For example, a program name must be on a fresh line. I get an error message. This can cover the widest array of problems. Read the manual carefully, it will tip you off to the kind of error you are looking for. If you have no idea what could have caused it, consult the appendix of the TI Guidebook for explanation of the error messages. I'm getting a result but it is wrong Check for Typing direct letters in place of pasting a command. For example, SIN ( X) can be entered using the ALPHA keys, but it is not the same as sin ( X) using the SIN key. Parenthesis mismatch. Count and match parentheses carefully. Subtraction vs. negative symbol. For example, the subtraction sign cannot be used to enter a -10.
