Maintenance

No user serviceable parts are to be found within 
the amplifier unit. Any maintenance or repair of the 
4020C unit should only be undertaken by qualified 
service personnel. 

Safety considerations

Although the 4020C has been designed in accord-
ance with international safety standards, the fol-
lowing warnings and cautions should be observed 
to ensure safe operation and to maintain the loud-
speaker under safe operating conditions:
 
•  Servicing  and  adjustment  must  only  be  
 

performed  by  qualified  service  personnel.  

 

The loudspeaker must not be opened.

•  Do  not  use  this  product  with  an  unearthed  
 

mains  cable  or  an  unearthed  mains  

 

connection  as  this  may  compromise  

 

electrical safety.

•  Do not expose the loudspeaker to water or  
 

moisture. Do not place any objects filled with 

 

liquid, such as vases on the loudspeaker or  

 

near it. 

•  This  loudspeaker  is  capable  of  producing  
 

sound  pressure  levels  in  excess  of  85 dB,  

 

which  may  cause  permanent  hearing  

 

damage.

•  Free  flow  of  air  behind  the  loudspeaker  is  
 

necessary  to  maintain  sufficient  cooling.  

 

Do  not  obstruct  airflow  around  the  

 

loudspeaker.

•  Note  that  the  amplifier  is  not  completely  
 

disconnected  from  the  AC  mains  service  

 

unless the mains  power  cord  is  removed  

 

from the amplifier or the mains outlet.
