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.
