Important Security Information

Please note and retain this manual. Carefully read and follow all of the 
safety and operating instructions before you use the machine. Be dou-
bly careful to follow all warnings and special safety instructions noted 
in this manual and on the unit. 

Connections: 

Only  use  the  connections  as  described.  Other  connec-

tions can lead to health risks and equipment damage.

Water and humidity:

 Do NOT use this machine anywhere near water 

(for example near a wash basin or bath, in a damp cellar, near swim-
ming pools, or the like). In such cases there is an extremely high risk of 
fatal electrical shocks!

Insertion  of  foreign  objects  or  fluids: 

NEVER  allow  a  foreign  object 

through any of the machine‘s chassis openings. You can easily come 
into contact with dangerous voltage or cause a damaging short circuit. 
NEVER allow any fluids to be spilled or sprayed on the machine. Such 
actions can lead to dangerous electrical shocks or fire! 

Opening the Unit:

 Do NOT open the machine housing, as there is great 

risk you will damage the machine, or – even after being disconnected – 
you may receive a dangerous electrical shock!

Electrical  power:

  Run  this  machine  ONLY  from  sources  which  can 

provide proper power at the prescribed rating. When in doubt about 
a source, contact your dealer or a professional electrician. To be sure 
you have isolated the machine, do so by disconnecting the power cord 
from your wall connection. Be sure that the power cord plug is always 
accessible. When not using the machine for a longer period, make sure 
to unplug it from your wall power socket. 

Power cord protection:

 Make sure that your power cord is arranged to 

avoid  being  stepped  on  or  any  kind  of  crimping  and  damage  related 
to such event. Do not allow any equipment or furniture to crimp this 
power cord.

Power  connection  overloads: 

Avoid  any  kind  of  overload  in  connec-

tions to wall sockets, extension or splitter power cords. Always keep 
manufacturer warnings and instructions in mind. Overloads create fire 
hazards and risk of dangerous shocks!

Lightning: 

Before thunderstorms or other severe weather, disconnect 

the  machine  from  wall  power  (but  to  avoid  life  threatening  lightning 
strikes, not during a storm). Similarly, before any severe weather, dis-
connect ALL the power connections of other machines and antenna and 
phone/network cables which may be interconnected so that no light-
ning damage or overload results from such secondary connections.
