Precautions
Installation
• Avoid placing the drive in a location subject to:
-high humidity
-high temperature
-excessive dust
-mechanical vibration
-direct sunlight
• CDU535 can be used in either a horizontal or vertical position.
Operation
• Do not move the drive during operation. This may cause it to
malfunction during reading.
• Avoid exposing the drive to sudden changes in temperature as
condensation may form inside the unit 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. If you operate the unit
right after a sudden increase
in temperature, it may malfunction during
