The message panel flashes SELFTEST
CTRL after power is applied and then
displays CHK 98. (The SEL LED might
not flicker, indicating that the drive
formatter is not polling the drive.)
Make sure a SCSI terminator is firmly installed on
the unused SCSI port on the back of the tape
drive CRU. Then turn power off and on again.
