Extended Self-test
The cardiograph's Extended Self-test, loaded as part of the system
software, tests each major subassembly. The display tests and the
printer test require visual verification of displayed or printed output.
In most cases, a test failure halts the test and a message indicating
the failure appears on the keyboard display. In the case of the tests
that require visual verification, visible failure symptoms appear in the
printed or displayed test pattern. See Chapter 6, "Troubleshooting,"
for a list of self-test failure messages and failure symptoms.
To begin the Extended Self-test, press (On-Standby) to turn on the
cardiograph, then quickly press and release the @FJ and (?J keys
simultaneously. The following display will appear:
