Testing Voltage Levels......
Following this "all tests passed" report, the TE-3000 will enter into the
normal display condition (see the following Section D) provided that the

any time after the completion of the self-test routine, the following
display will be shown.
If any test fails during this power-up self-test sequence, it will be noted
on the display for that particular test. The displays will resemble the
previous sequence shown above but if any failure is encountered, the OK
will be replaced by BAD and PASSED will be replaced by FAILED!.
