10. Handling

• Never connect the mains plug to a mains socket immediately after the device has been taken from a cold
to a warm environment. The resulting condensation may destroy the device.
Allow the device to reach room temperature before connecting it. Wait until the condensation has eva-
porated.
• Never pull the mains plug from the mains socket by the cable. Only pull it from the mains socket by the
intended grip areas.
• Unplug the mains plug from the mains socket if you are not using the device for an extended period of
time.
• Disconnect the mains plug from the mains socket during thunderstorms for reasons of safety.
• Do not listen to excessively loud music over an extended period of time. This may damage your hearing.

11. Maintenance

Periodically verify the technical safety of the device, e.g. check for damage to the mains cable or the
casing.
If you have reason to believe that the device can no longer be operated safely, disconnect it immediately
and make sure it is not operated unintentionally. Pull the mains plug from the mains socket!
It can be assumed that safe operation is no longer possible if:
• there is visible damage to the device or to the mains cable
• the device no longer works
• the device has been stored under unfavourable conditions for an extended period of time or
• after exposure to extraordinary stress caused by transport
Always observe the following safety information before cleaning or servicing the device:
Live components may be exposed if covers are opened or components are removed.
The device must be disconnected from all power sources before any servicing or repair work is
carried out.
Capacitors inside the device may still carry voltage even though they have been disconnected
from all power sources.
Only qualified experts familiar with the hazards involved and the relevant regulations must per-
form repairs.
Cleaning
Clean the exterior of the device with a soft, dry cloth or brush only. Never use any aggressive cleansing
agents or chemical solutions since these may damage the casing or impair its function.
