Avoid sudden changes in temperature
Abnormal occurrences
Cabinet cleaning
If the drive is moved from a cool place to a warm place, or if the room
temperature suddenly rises, moisture may condense inside the case. After a
sudden change in temperature, wait at least one hour before turning the drive
on.
Inserting a cartridge with condensation inside the drive can damage the drive
or the tape. Immediately remove cartridges in the drive if there is a possibility
that there is condensation inside.
Leaving the drive on without inserting cartridges, moreover, will quickly
evaporate any condensation.
If the drive behaves abnormally, or if it begins to smell or smoke,
immediately unplug it from the wall outlet and contact your supplier for
assistance.
Wipe the cabinet with a soft dry cloth. For heavy dirt, wipe with a soft cloth
moistened with a gentle liquid soap, then wipe again with a soft dry cloth. Do
not use alcohol, paint thinner, bug sprays or other volatile solvents, as they
can damage the finish.
