For your safety, never remove the PC’s cover without 
first removing the power cord from the power outlet 
and any connection to a telecommunications network. 
If a power protection device is fitted to your PC, you 
must remove the power cord then wait for a complete 
shutdown of your system before removing the cover. 
Remove the power protection device cables before any 
servicing operation. Always replace the cover before 
switching the PC on again.
To avoid electric shock and harm to your eyes by laser

requirements and wavelength. This product is a class
