the instructions, may cause harmful interference to radio communications.  
However, there is no guarantee that interference will not occur in a particu-  
lar installation. If this equipment does cause harmful interference to radio  
or television reception, which can be determined by turning the equipment  
off and on, the user is encouraged to try to correct the interference by one  
or more of the following measures:  
Reorient or relocate the receiving antenna.  
Increase the separation between the equipment and receiver.  
Connect the equipment into an outlet on a circuit different from that to  
which the receiver is connected.  
Consult the dealer or an experienced radio/TV technician for help.  
This class B digital apparatus complies with the Canadian ICES-003.  
Changes or modifications made to this equipment not expressly approved  
by Sennheiser electronic Corp. may void the FCC authorization to operate  
this equipment.
