SAFETY AND WARRANTY INFORMATION

The Safety and Warranty Information section provides details about cautionary

symbols used in the manual, safety markings used on the instrument, and

information about the Warranty including Customer Service contact information.

Safety Information and the Manual

Throughout this manual, you will see the words Caution and Warning indicating

potentially dangerous or hazardous situations which, if not avoided, could result in

death, serious or minor injury, or damage to the product. Specifically:

Caution indicates a potentially hazardous situation which can result in minor or

moderate injury or damage to the product or equipment.

Warning indicates a potentially dangerous situation which can result in serious injury or

death.

WARNING

Visible and/or invisible laser radiation. Avoid direct exposure to the beam.

General Safety Considerations

If any of the following conditions exist, or are even suspected, do not use the

instrument until safe operation can be verified by trained service personnel:

•Visible damage

•Severe transport stress

•Prolonged storage under adverse conditions

•Failure to perform intended measurements or functions

If necessary, return the instrument to ILX Lightwave, or authorized local ILX

Lightwave distributor, for service or repair to ensure that safety features are

maintained (see the contact information on page xi).

All instruments returned to ILX Lightwave are required to have a Return

Authorization Number assigned by an official representative of ILX Lightwave

Corporation. See Returning an Instrument on page ix for more information.
