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 dou­bly 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 connec­tions 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 swimming
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 connec­tions 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, dis­connect ALL the power connections of other machines and antenna and
phone/network cables which may be interconnected so that no light­ning damage or overload results from such secondar y connections.

Important Security Information

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 inches 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 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 and immediately contact a qualified tech­nician when you think repairs are needed – or when moisture or for­eign objects may accidentally have gotten in to the housing, or in
cases when the machine 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 cord or its plug, first consider turning
off the main circuit breaker before unplugging the power cord.

Replacement/substitute parts: Be sure that any ser vice 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
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.
