nected to the PA box.
• Make sure the mains cable is not pinched, bent, damaged by sharp edges or other-
wise subjected to mechanical strain. Avoid excess thermal stress on the mains cable
due to excessive heat or cold. Do not modify the mains cable. This may damage the
mains cable. A damaged mains cable can result in a life-threatening electric shock.
• Do not touch, when the mains cable is damaged. First, switch off the appropriate
mains socket (e.g. via the respective RCD and the circuit breaker) and then carefully
pull the mains plug from the mains socket. Separate the mains cable from the device.
Never use the product if the mains cable is damaged.
• To completely separate the device from the mains, you have to unplug the mains
plug from the wall socket. It is not sufficient to turn off the PA box through the on/off

• Never pour liquids over electrical devices and never place objects filled with liquid
on top of them (e.g. vases). You run the risk of causing a fire or a fatal electric shock.
If this is the case, cut the power to the appropriate mains socket (e.g. switch off the
RCD and the circuit breaker) and then remove the mains plug from the mains socket.
Disconnect all cables from the device. Do not use the product afterwards. Take it to
a specialized workshop.
• Do not place open sources of fire such as burning candles on the appliance.
