25 Safety instructions

Never open electronic devices! Servicing and programming must only be
done by authorised personnel and is all the more important for current-
carrying units. If devices are opened by customers in breach of this
instruction, the warranty becomes null and void.
Keep the receiver away from central heating radiators and electric
heaters.
Use a damp cloth for cleaning the receiver. Do not use any cleansing
agents or solvents.

26 Error messages

The display of the receiver is also used by the integrated microprocessor to
display error messages for service purposes. If you see error messages such
as „EE_DEF" or „rS_232", there is a fault in the receiver unit which can only
be corrected by your local Sennheiser service department.
