Precautions
Installation
Avoid placing the drive in a location subject to:
- high humidity
- high temperature
- mechanical shock and vibration
- direct sunlight
Operation
• Do not move the drive while it is operating. It may cause malfunction.
• Avoid exposing the drive to sudden changes from a low to high in temperature. This
may cause water condensation to collect inside the drive. If the ambient
temperature should suddenly rise while the drive is turned on , wait at least one
hour before turning on the drive. If you attempt to operate the drive immediately
after a sudden increase in temperature, a malfunction may occur.
• Do not turn off the drive while the tape is in the drive.
Transportation
• Keep the original packing materials to facilitate transportation of the drive.
• Always remove the tape before moving the drive. After removing the drive from the
computer, repack the drive into its original packing.
