1 This occurs during writes where an excessive number of read-after-write
errors occur and during reads where an excessive level of C3 correction
is being applied. This indication would persist until the cassette is
unloaded.
2 The termination resistor problem occur only at power-on time, and the
tape drive appears to have hung during self-test.
3 Indicates a failure of the DDS field replaceable unit.[REV END]
