7)  Do  not  block  any  ventilation  openings.  Install  in  accordance  with  the  user 
manual.

8) Do not install near any heat sources such as radiators, heat registers, stoves or 
other apparatuses that produce heat.

9) Protect the power cord from being walked on, pinched or damaged in any 
other way. Pay particular attention to plugs and the point where they exit from 
the amplifier.

0) The amplifier may only be used in accordance with the information provided 
in the user manual. Before and during the usage of the amplifier please ensure 
that all recommendations, especially the safety recommendations as detailed in 
the user manual, are adhered to.
The 

D-POWER 

Amplifier is designed for the amplification of pulsed audio signals 

and the amplifier should only be connected to speakers with an average impe-
dance as indicated.

) Do not place this amplifier on an unstable cart, stand, 
tripod,  bracket  or  table.  The  device  may  fall,  causing 
serious injury and serious damage to the device itself.

2) The amplifier can only be disconnected from the power supply by removing

during lightning storms or when unused for long periods of time.

3) Refer all servicing to qualified service personnel. 
Servicing is required when  

   the power-supply cord or plug has been damaged, 
   liquid has been spilled or objects have fallen into the amplifier, 
   the amplifier has been exposed to rain or moisture, 
   the amplifier has been dropped or suffered damage in any other way,
    the amplifier exhibits a distinct change from its normal function or 

performance.
