install it near heat emitting appliances, such as a room heater or stove.

No naked flame sources such as lighted candles should be placed near the device.
Operate the device in a place where the temperature is between -20°C and 50°C (-4°F to 122° F). Avoid 

dramatic changes in temperature or humidity when using it, as condensation may form on or within the 
device.

During the use, it is normal for the device to get warm. The exterior of the device functions as a cooling 

surface that transfers heat from inside the unit to the cooler air outside.

The device should be placed so that its location does not interfere with its proper cooling. For example, 

the device shouldn’t be placed on beds, carpets or similar surfaces that could create an obstacle for the 
ventilation openings.

To reduce the risk of electric shock, unplug the power cord before connecting audio cables.
Set up your device on a stable horizontal surface. If combined or mechanically connected with other products, 
always verify the stability of the system set up. Install the unit only in a location that can structurally support 
the weight of the unit, far away from people who can interfere with the stability of the system. In case 
of  outdoor  installation,  assure  that  the  wind  does  not  interfere  with  the  system’s  stability,  taking  extra 
securities like chains, weights, ropes or any other certified anchoring systems.  Doing otherwise may result 
in the unit falling down, causing personal injury or property damage. Doing otherwise may result in the unit 
falling down, causing personal injury or property damage. The system should only be suspended by qualified 
personnel following safe rigging practices. Secure fixings to the building structure are vital. To clarify any 
doubt you may have, seek help from architects, structural engineers or other specialists.
Protect the power cord from being walked on or pinched.

This audio system is not intended for use in the operation of nuclear facilities, aircraft navigation or 
communication systems, air traffic control systems,or for any other uses where the failure of the audio 

system could lead to death, personal injury, or sever environmental damage.

Do not make repairs yourself.

  Caution,  risk  of  electric  shock.  Do  not  open  the  device,  it  contains 

potentially hazardous voltage. Never attempt to disassemble, repair or modify the system yourself.  
Disassembling the unit may cause damage that is not covered under the warranty. The device contains no 
user-serviceable parts. Repairs should only be performed by factory trained service personnel. Do not plug 
the power cord if you suspect that your device needs service or repair.

Voltage requirement.

 Make sure that the supplied voltage stays within the specified range. Verify that your 

mains connection satisfies the power ratings of the device. 

Only connect the power supply to an appropriate power outlet.  
Warning:  The  device  must  be  only  connected  to  an  AC  three-wire  grounding  outlet.  If  your  outlet  isn’t 

grounded, contact a licensed  electrician to replace it  with a property grounded outlet. 

Warning:  connecting  the  system  to  an  AC  power  mains  with  a  voltage  exceeding  270  V  will  cause 
significant damage to the device and create a serious risk for users!

The devices which feature powerCON connectors allow power supply to other devices from the 
white outlet socket. The maximum power value which can be picked up from that socket changes 

according to the device model. Please, read the user manual carefully.
