Security Advices

Controls and switches

Operate the controls and switches only as described in the manual. Incorrect adjustments 
outside safe parameters can lead to damage and unnecessary repair costs. Never use the 
switches or level controls to effect excessive or extreme changes. 

Repairs

Unplug the unit from all power and signal connections and immediately contact a quali-
fied technician when you think repairs are needed – or when moisture or foreign objects 
may accidentally have reached inside the housing, or in cases when the device may have 
fallen and shows any sign of having been damaged. This also applies to any situation in 
which the unit has not been subjected to any of these unusual circumstances but still is 
not functioning normally or its performance is substantially altered. In cases of damage 
to the power supply and cord, first consider turning off the main circuit breaker before 
unplugging the power cord.

Replacement/substitute parts

Be sure that any service technician uses original replacement parts or those with identical 
specifications as the originals. Incorrectly substituted parts can lead to fire, electrical 
shock or other dangers, including further equipment damage. Safety inspection: Be sure 
always to ask a service technician to conduct a thorough safety check and ensure that the 
state of the repaired device is in all respects up to factory standards.

Cleaning

Do not use any solvents, as these can damage the chassis finish. Use a clean, dry cloth (if 
necessary, with an acid-free cleaning oil). Disconnect the device from your power source 
before cleaning

Notes on Environmental Protection 

At  the  end  of  its  operating  life,  this  product  must  not  be  disposed  of  with  regular 
 household waste but must be returned to a collection point for the recycling of electrical 
and electronic equipment. The wheelie bin symbol on the product, user‘s manual and 
packaging indicates that. The materials can be reused in accordance with their markings. 
Through  reuse,  recycling  of  raw  materials,  or  other  forms  of  recycling  of  old  products, 
you are making an important contribution to the protection of our environment. Your local 
administrative office can advise you of the responsible waste disposal point.
