Repair work is also required if the device is not working properly or has been
dropped. If smoke is produced, or there are any unusual sounds or smells, turn
the headphones off immediately. In such cases, the headphones should not be
used until they have been inspected by authorised service personnel. Only
have the device repaired by qualified personnel. Never open the housing of
