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.
