the warranty becomes void. Incorrect operation may lead to danger e.g: short-circuit, burns and electric shocks etc.
Do not endanger your own safety and the safety of others!
Incorrect installation or use can cause serious damage to people and/or property.
• Speaker & Amplier systems can produce high sound
pressure levels, please operate all controls with caution to
ensure people are not exposed to excessive or dangerous
sound pressure levels.
• Never let the power cable come into contact with other
cables. Handle the power cable and all mains voltage
connections with particular caution!
• Never remove warning or informative labels from the unit.
• Do not open the equipment and do not modify the unit.
• Do not switch the equipment on and off in short intervals,
as this will reduce the system’s life.
• Only use the equipment indoors.

• Always disconnect the power from the mains when
equipment is not in use or before cleaning! Only handle
the power-cable by the plug. Never pull out the plug by
pulling the power-cable.
• Make sure that the available voltage
is between 220-240V, 50/60Hz AC or 24V DC.
• Make sure that the power cable is never crimped or
damaged. Check the equipment and the power cable
periodically.
• If the equipment is dropped or damaged, disconnect the
mains power supply immediately and have a qualied
engineer inspect the equipment before operating again.
• If the equipment has been exposed to drastic
temperature uctuation (e.g. after transportation),
