©(ignore) will bring up the main screen directly. If any of the failed selftests involve actual

testing circuitry (eg. FMxx), the operator will not be permitted to actually run a test cycle. File
manipulation, RD Test and System setting changes are possible, however.

Debug has three main keys: ©(run), ©(display), ©(prt_res). The last one means "print
results" and sends a formatted listing of all test results from the last test(s) executed to the serial
RS232 port, "display" brings to the screen, the characteristic 4 b)4e in^vidual result of the test
whose number was entered on the command line. This test must first have been run, either

explicitly or during the powerup.

The key labels under "run" are words that can be used to compose a command line instmction.
