for an extended period of time.
• For safety reasons, disconnect the mains plug from the mains socket during thun-
derstorms.
• Ensure that the mains cable is not squeezed, bent, damaged by sharp edges or
subjected to mechanical stress. Avoid excess thermal stress on the mains cable
due to excessive heat or cold. Do not modify the mains cable. Failure to adhere
to these instructions may lead to damage of the mains cable. A damaged mains
cable can cause a fatal electric shock.
• Do not touch the mains cable if there are any signs of damage. Power down the
respective mains socket (e.g. via the respective circuit breaker), and then carefully
unplug the mains plug from the mains socket. Never use the product if the mains
cable is damaged.
• Damaged mains cables must be replaced by the manufacturer, an authorised re-
pair centre or a qualified electrician.
• Never connect or disconnect power plugs when your hands are wet.
• Only use the power cable and power adapter supplied with the product and certi-
fied for use in your country.
