CE Declaration of Conformity

The system should be powered down when not in use.

The Core Tile generates, uses, and can radiate radio frequency energy and may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment causes harmful interference to radio or television reception, which can be determined by turning the equipment off or on, you are encouraged to try to correct the interference by one or more of the following measures:

  • ensure attached cables do not lie across the card

  • reorient the receiving antenna

  • increase the distance between the equipment and the 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


It is recommended that wherever possible shielded interface cables be used.
