USER’S MANUAL

Safety Instructions

The following safety instructions must be observed whenever the unit is operated, serviced, or repaired. Failure to comply with any of these instructions or with any precaution or warning contained in the user’s manual is in direct violation of the standards of design, manufacture, and intended use of the unit. JDS Uniphase assumes no liability for the customer’s failure to comply with any of these safety requirements.

Before Initializing and Operating the Unit

Inspect the unit for any signs of damage, and read the user’s manual thoroughly.

Install the unit as specified in the Getting Started section.

￿Ensure that the unit and any devices or cords connected to it are properly grounded.

Operating the Unit

Warning

To avoid the risk of injury or death, always observe the following precautions before initializing the unit:

•To prevent hazardous radiation exposure, use only the controls or adjustments and perform only procedures specified for the laser source.

•If using a voltage-reducing autotransformer to power the unit, ensure that the common terminal connects to the earthed pole of the power source.

•Use only the type of power cord supplied with the unit.

•Connect the power cord only to a power outlet equipped with a protective earth contact. Never connect to an extension cord that is not equipped with this feature.

•Willfully interrupting the protective earth connection is prohibited.

•Never look into the end of an optical cable connected to an optical output device that is operating. Laser radiation is invisible, and direct exposure can severely injure the human eye. For more information, see the user’s manual of the laser source in use.

•Do not use the unit outdoors.

•To prevent potential fire or shock hazard, do not expose the unit to any source of excessive moisture.

•Do not operate the unit when its covers or panels have been removed.

•Do not interrupt the protective earth grounding. Any such action can lead to a potential shock hazard that can result in serious personal injury.

•Do not operate the unit if an interruption to the protective grounding is suspected. In this case, ensure that the unit remains inoperative.

•Use only the type of fuse specified by JDSU as appropriate for this unit. Do
