Precautions
■Installation
• Avoid placing the drive in a location subject to:
–high humidity
–high temperature
–excessive dust
–mechanical vibration
–direct sunlight.
We recommend to use the drive in a horizontal position. Do not use
it in a tilted position.
■Operation
• Do not move the drive during operation. This may cause it to
malfunction during reading or writing.
• Avoid exposing the drive to sudden changes in temperature as
condensation may form on the lens inside the drive as a result.
Should the surrounding temperature suddenly rise while the drive
is on, wait at least one hour before you turn off the power.
Operating the drive immediately after a sudden increase in
temperature, may result in a malfunction during reading or
writing.
■Transportation
• Keep the original packing materials for future transport of the
drive.
• Remove the caddy before moving the drive and, if you take the
drive out of the computer, repack the drive as you received it.
