SERVICE AND REPAIR PROCEDURES
4.1 GUIDELINES
r All the tools and supplies you need to perform a specific procedure are listed under
Tools/Supplies Needed, at the beginning of the applicable procedure.
r Each time you are told to turn the instrument’s power ON, you should have the Program
Disk in the floppy disk drive.
r If you are told to let the system reach the Main Menu and it does not, or you are told to
perform a System Verification Procedure (SVP) and the system fails, you will have to
troubleshoot the problem. Refer to Chapter 7, Troubleshooting, for guidelines.
r Verify that each connector has a label. Tracing where each connector goes when
installing the new card would be very time consuming without labels.
