Earth
The earth has to be connected! If the device will be
directly connected with the local power supply network,
a disconnection switch with a minimum opening of 3
mm at every pole has to be included in the permanent
electrical installation. The device must only be
connected with an electric installation carried out in
compliance with the IEC standards. The electric
installation must be equipped with a Residual Current
Device (RCD) with a maximum fault current of 30 mA.
Installation
Do not shake the device. Avoid brute force when
installing or operating the device. When choosing the
installation spot, please make sure that the device is
not exposed to extreme heat, moisture or dust. There
should not be any cables lying around. You endanger
your own and the safety of others!
Ambient Conditions
This device must never be operated or stockpiled in
surroundings where splash water, rain, moisture or fog
may harm the device. Moisture or very high humidity
can reduce the insulation and lead to mortal electrical
shocks. When using smoke machines, make sure that
the device is never exposed to the direct smoke jet and
is installed in a distance of 0.5 meters between smoke
machine and device. The ambient temperature must
always be between -5° C and +45° C. Keep away from
direct insulation (particularly in cars) and heaters. The
relative humidity must not exceed 50 % with an ambient
temperature of 45° C. This device must only be
operated in an altitude between -20 and 2000 m over
NN. The ambient contamination must never exceed
level 1 and must not be conducting, only dry. Never use
the device during thunderstorms. Over voltage could
destroy the device. Always disconnect the device
during thunderstorms.
Transport
Please use the original packaging if the device is to be
transported.
Cleaning
Never use solvents or aggressive detergents in order to
clean the device! Rather use a soft and damp cloth.
Operation
Operate the device only after having familiarized with its
functions. Do not permit operation by persons not
qualified for operating the device. Most damages are
the result of unprofessional operation!
Serial Barcode
Never remove the serial barcode from the device as
this would make the guarantee void.
Modifications and Guarantee
Please note that damages caused by manual
modifications on the device or unauthorized operation
by unqualified persons are not subject to warranty.
If this device will be operated in any way different to the
one described in this manual, the product may suffer
damages and the guarantee becomes void.
Furthermore, any other operation may lead to dangers
like short-circuit, burns, electric shock, etc.
Avoiding Hearing Loss
By operating amplifying systems, you can produce
excessive sound pressure levels that may lead to
permanent hearing loss. Please refer to the
explanations under "Legal instructions".
Public and Industrial Use
Operating an amplification system in public or industrial
areas, a series of safety instructions have to be
followed that this manual can only give in part. The
operator must therefore inform himself on the current
safety instructions and consider them.
