TI-86 error code 08 number base - Texas Instruments TI-86 Calculator

The - key is for subtraction, an operation that needs two numbers. If you press - as the first key on a line, the calculator assumes you want to subtract something from the previous answer, Ans.

If you want to enter a negative number, use the (-) key on the bottom row of the keyboard, just to the left of the Enter key.

Every time you change batteries this will happen to you. First press 2nd then press and hold the down arrow. Hold until their is no black in the background but you can still see the numbers on the screen.

The TI 86 has two logarithmic functions: natural logarithm (ln) and common (decimal) logarithms (log). If you need the logarithm in any other base than e or 10 you need to use one of the two equivalent expressions
log_b(x) =ln(x)/ln(b) =log(x)/log(b)
Here b is the value of the base of the logarithm and x is the argument (the value whose logarithm you are seeking). Of course the argument x must be a positive number.
Note: On the TI 86 the log function can calculate the logarithm of a complex number, according to the manual.

You apparently have the base set to something other than decimal. Press 2nd [MODE]. Use the arrow keys to move down to the sixth line, select "Dec", then press EXIT.

Having gone over a month without a response to my query, I assume my suggestions solved the problem.

To restore memory on a TI 84 to factory settings follow the directions on pages 108 and 109 of the instructions manual (TI 84 Plus Silver). Otherwise look in the index for RESET MEMORY to get the right page. Be sure you read the precaustions!!!!!!

Hello,
Read the following answer from the TI Knowledge Base.
Hope it helps.

How can I troubleshoot an Error in Xmit error message when transferring data between two graphing calculators?

The Error in Xmit error message is returned when a connection cannot be established between two calculators when attempting to transfer data. There are several factors that can contribute to this error message.
• The calculators being connected are not compatible for data transfer.
• The data cable is not firmly connected to both units.
• The receiving calculator is not in receive mode.
• The I/O port on one of the graphing calculators is damaged.
The procedure for connecting two graphing calculators is as follows:

• Connect the data cable to the I/O port of each unit. The cable will fit tightly in the I/O port and snap into place. If silver from the cable is visible, the cable is not properly connected.
• Access the Link menu on each unit
• Place the receiving graphing calculator on "Receive"
• Place the sending unit on "Transmit" or "Send" from the Link menu.

Once the data has been selected, the transfer will commence accordingly.

The data transfer protocols for graphing calculator is as follows:

• TI-73 - Link allows data sharing with another TI-73, TI-82, TI-83, and TI-83 Plus.
• TI-82 - Link allows data sharing with another TI-82.
• TI-83 - Link allows data sharing with the TI-82, TI-83 family calculator, and TI-84 Plus family calculator.
• TI-83 Plus/TI-84 Plus family- Link allows data sharing with another TI-82, TI-83 family calculator, and TI-84 Plus family calculator.
• TI-85 - Link allows data sharing with another TI-85(To a TI-86. Not From a TI-86).
• TI-86 - Link allows data sharing with another TI-86 and from a TI-85 to a TI-86.
• TI-89 family- Link allows data sharing with another TI-89 family calculator and from a TI-92 family calculator.
• TI-92 family- Link allows data sharing with another TI-92 family calculator and from a TI-89 family calculator.
• Voyage™ 200 - Link allows data sharing with another Voyage 200 and TI-92 family calculator.



If the cable does not fit properly into the I/O port, or if the I/O port appears to be damaged (broken or separated plastic, obstruction inside the port), call 1-800-TI-CARES (1-800-842-2737) M-TH 8:00 AM - 7:00 PM FRI 10:00 AM - 7:00 PM Central Standard Time to speak to a representative or sending an email to [email protected].

Press "2ND" "MATH" "F3" to invoke the Angle menu.

Enter the number of degrees, press "F3", enter the number of minutes, press "F3", enter the number of seconds, press "F3", then press "ENTER".

You're trying to reference a variable or use a function where it is invalid. If you're still struggling with this, post a little more detail as to exactly what you're trying to plot.

Most likely you're trying to graph a function while you have the stat plot turned on. Turn off the stat plot and try it again.
