■ Remove the cassette before turning the power "OFF". The tape life might be
shortened or a malfunction might occur during the backup process if the power is
turned "OFF" while the cassette is still inside.
Note – If the "cleaning lamp" starts blinking immediately after completion of a
cleaning operation, the data cassette might have been damaged. In this case, replace
the data cassette.
