User Safety 

Introduction

Your safe and effective use of this product is of utmost importance to us at Newport. Please read the 
following amplifier safety information before attempting to operate the amplifier.  There are no 
user-serviceable parts inside the optical head or the controller.  No attempt should be made to open 
either component and doing so voids the factory warranty.  Any use of the amplifier system that is not 
in compliance with the instructions in this manual may compromise the safety of the user, and the 
performance and/or longevity of the device.  It is recommended that all safety and operation 
procedures are followed carefully. 

Usage of Symbols

Several symbols have been used throughout this manual.  An explanation of these symbols is given 
here. 

Symbol Explanation 

 

Warning.  This symbol warns the user of a 
potential danger – either electrical or optical.

 

Caution.  This symbol notifies the users that 
extra caution should be exercised when 
performing procedures discussed in that 
section. 

 

This symbol notifies the user of a special 
consideration that should be noted. 

Laser and Amplifier Safety

The laser radiation emitted from this unit may be harmful. Always follow these precautions: 

 

Avoid direct skin or eye exposure to the beam. 

 

Avoid looking directly at the beam or at radiation scattered from the beam. 

 

Be aware of and follow the warnings on the safety labels (examples are shown on following 
pages). 

 

The amplifier will exhibit a five-second delay before emitting light after pressing the on 
button, as mandated by the US FDA.
