OPERATIONAL SAFETY 

 

 

WARNING 

 

Operation  of  electronic  equipment  involves  the  use  of  voltages  and  currents  that 
may  be  dangerous  to  human  life.  Note  that  under  certain  conditions  dangerous 
potentials may exist in some circuits when power controls are in the 

OFF

 position. 

Maintenance personnel should observe all safety regulations. 

 

Do  not  make  any  adjustments  inside  equipment  with  power 

ON

  unless  proper 

precautions are observed. All internal adjustments should only be made by suitably 
qualified  personnel.  All  operational  adjustments  are  available  externally  without 
the need for removing covers or use of extender cards. 

 
 
 

 
 

 

Optical Safety 

 

The  light  emitted  from  the  LASER  diode  used  in  this  system  is 
invisible  and  may  be  harmful  to  the  human  eye.  Avoid  looking 
directly  into  the  fibre  optic  cable  or  connectors  or  into  the 
collimated beam along their axis when the device is in operation. 
Operating  the  LASER  diode  outside  of  its  maximum  ratings  may 
cause device failure or a safety hazard.
