scanning the frequency band of 10 KHz to 12 MHz. An indicated power 
output of 200W should be maintained during this operation. 

 
 
 
 
 
 
4.5     PACKAGING FOR RESHIPMENT 
 
In the event of the equipment being returned for servicing it should be packed in 
the original shipping carton and packing material. If this is not available, wrap the 
instrument  in  heavy  paper  or  plastic  and  place  in  a  rigid  outer  box  of  wood, 
fiberboard  or  very  strong  corrugated  cardboard.  Use  ample  soft  packing  to 
prevent  movement.  Provide  additional  support  for  projecting  parts  to  relieve 
these  of  unnecessary  shock.  Close  the  carton  securely  and  seal  with  durable 
tape. Mark the shipping container FRAGILE to ensure careful handling. 

 

 

 
Chapter 5 Safety: 
 

Do  not  attempt  to  operate  this  unit  with  the  cover  removed.  High  AC  and  DC 
voltages are present. The cover protects against electrical shock due to AC line 
voltages,  high  DC  and  RF  fields.  Further  the  cover  provides  part  of  the  cooling 
system  design.  Components,  specifically  on  the  RF  driver  board  are  prone  to 
over-heat and eventual failure if the unit is operated without the cover in place. 
 

Removal of the cover voids the Warranty 

 
Ensure that the load is connected to the output prior to connecting the RF input 
to  the  unit.  This  will  prevent  high  voltages  being  present  and  exposed  at  the 
output connector.  
 
Only use the AC cord provided or equivalent.  
 
Ensure that the mains outlet is properly grounded.
