SAFETY INSTRUCTIONS 

 

 

 

                          DANGEROUS HIGH VOLTAGE INSIDE! 

 

The power amplifier is using high voltage up to 3200V DC, which is very dangerous for human 
life!  Read  next  safety  instructions  carefully  first,  before  you  will  start  to  install  and  operate 
power amplifier!   NEVER VIOLATE NEXT RULES! 

 

NEVER ALLOW CHILDREN to play around PA or to touch power amplifier or connected cables 
in working condition, or to push anything into the case holes! 

 

Never  turn  the  amplifier  on  without  the  upper  lid  in  place.    DO  NOT  ATTEMPT  TO  SHORT  OR 
BYPASS safety switch under upper lid! 

 

The    amplifier  is  neither  to  be  used  in  a  WET  or  HUMID  environment  nor  to  be 
exposed to RAINFALL! 

 

Do not turn the amplifier ON without having connected the ANTENNA or properly rated DUMMY 
LOAD!  A  hazardous  HF  voltage  may  build  up  on  the  antenna  connector  after  turning  the 
amplifier on with no antenna or dummy load connected! 

 

Before  opening  the  upper  lid  of  the  amplifier  make  sure  that  power  supply  has  been 
disconnected  AT  LEAST  10  minutes  allowing  the  electrolytic  capacitors  to  discharge  fully. 
Disconnect power cord from the outlet!  

 

Any work inside the PA (internal fuses replacement, tube replacement, etc.) can be carried out 
only by professionally qualified person!
