Do not defeat the safety purpose of the polarized or grounding type plug. A 

polarized  plug  has  two  blades  with  one  wider  than  the  other.  A  grounding 
type plug has two blades and a third grounding prong. The wide blade or the 

third prong are provided for your safety. If the provided plug does not fit into 

your outlet, consult an electrician for replacement of the obsolete outlet. 

10.

 

Protect the power cord from being walked on or pinched particularly at the 
plugs,  convenience  receptacles,  and  at  the  point  where  they  exit  from  the 

apparatus. 

11.

 

Only use attachments/accessories specified by the manufacturer. 

12.

 

Unplug  the  apparatus  during  lightening  sorts  or  when  unused  for  long 

periods of time. 

13.

 

Refer  all  servicing  to  qualified  personnel.  Servicing  is  required  when  the 
apparatus has been damaged in any way, such as power supply cord or plug 

is damaged, liquid has been spilled or objects have fallen into the apparatus, 

the  apparatus  has  been  exposed  to  rain  or  moisture,  does  not  operate 
normally, or has been dropped.

Disconnecting from mains: Switching off the POWER switch all the functions 

and light indicators of the amplifier will be stopped, but fully disconnecting 

the  device  from  mains  is  done  unplugging  the  power  cord  from  the  mains 
input socket. For this reason, it always shall remain readily operable. 

15.

 

Equipment  is  connected  to  a  socket-outlet  with  earthing  connection  by 

means of a power cord.
