Control

Air circulation: 

Chassis openings offer ventilation and serve to protect 

the  machine  from  overheating.  NEVER  cover  or  otherwise  close  off 
these openings. NEVER place the machine on a soft surface (carpet, 
sofa, etc.). Make sure to provide for a mounting space of 4-5 cm/2 inch-
es to the sides of the unit when mounting the unit in racks or cabinets.

Controls  And  switches: 

Operate  the  controls  and  switches  only  as 

described  in  the  manual.  Incorrect  adjustments  outside  safe  para- 
meters 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  and  immediately  contact  a  qualified  tech-

nician when you think repairs are needed – or when moisture or for-
eign  objects  may  accidentally  have  gotten  in  to  the  housing,  or  in 
cases when the machine may have fallen and shows any sign of hav-
ing 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 al-
tered. 

 

 

 

 

 

 

In cases of damage to the power cord or its plug, 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 con-

duct a thorough safety check and ensure that the state of the repaired 
machine is in all respects up to factory standards.

Cleaning: 

In 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 machine from your power source before 
cleaning.
