This is the Media Caution Signal.
1 Wait for the current operation to finish, then insert
a different tape and repeat the operation that was
being performed.
2 If the media caution signal does not show this time,
it indicates that the original cartridge was nearing the
end of its useful life. Copy any data you want to keep
from the original tape onto a new tape if possible,
then discard the old tape.
3 If the media caution signal appears again with the
second tape, the tape heads need cleaning.
4 If the media caution signal appears after using a
cleaning cartridge, the cleaning cartridge has
probably expired and should be discarded.
