If your math coprocessor does not seem to be operating properly, check the following:
1.Run the Setup program on your Reference diskette and check to make sure that the math coprocessor is listed as installed on the Exit display. If it is listed as not installed, you or your dealer may have installed the math coprocessor incorrectly. See Chapter 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 the coprocessor.
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 the math coprocessor for any additional procedures you may need to perform or any troubleshooting information.
3.If you are still having trouble with your math coprocessor, test the coprocessor by running the System diagnostics program on your Reference diskette. See Appendix E for instructions. If your math coprocessor came with its own diagnostic programs, check the documentation that came with it and run those tests also.
