ROM-Based Diagnostics and Calibration
Comprehensive internal IBASIC diagnostics are provided to aid in
troubleshooting the Test Set. These diagnostic programs use external cabling
and the internal measurement and path setting capabilities of the Test Set to
diagnose itself for RF and audio hardware problems. No external test
equipment is necessary.
As the diagnostic programs execute, detected problems will be reported with a
suggested defective assembly and it's probability of failure. Refer to the
appropriate Assembly Level Repair section for more information.
