Math Coprocessor Problems
If your math coprocessor does not seem to be operating properly, check the following:
1.Run the SETUP program and check to make sure that the math coprocessor is listed as Installed on the SETUP display. If it is listed as Not installed, you or your dealer may have installed the coprocessor incorrectly. See Chapters 2 and 5 for more information.
Caution
Do not attempt to remove the math coprocessor yourself. Contact your dealer for information about a special extraction tool that is needed to remove it.
2.If your math coprocessor is listed as Installed in the SETUP program but still does not seem to be working, check the manual that came with it for troubleshooting information and for any diagnostic procedures you can perform.
