CE Declaration of Conformity

The system should be powered down when not in use.

It is recommended that ESD precautions be taken when handlingRealView ICE and RealView Trace equipment.

The RealView ICE and RealView Trace modules generate, use,and can radiate radio frequency energy and may cause harmful interferenceto radio communications. However, there is no guarantee that interference willnot occur in a particular installation. If this equipment causesharmful interference to radio or television reception, which canbe determined by turning the equipment off or on, you are encouragedto try to correct the interference by one or more of the followingmeasures:

  • ensureattached cables do not lie across the card

  • reorient the receiving antenna

  • increase the distance between the equipment andthe receiver

  • connect the equipment into an outlet on a circuitdifferent from that to which the receiver is connected

  • consult the dealer or an experienced radio/TV technicianfor help

Note

It is recommended that wherever possible shielded interfacecables be used.
