</span>I suppose, if there is provision to "plug in" a radio module, the CE<br>
declaration is made much simpler. If the radio module is available to end<br>
users and they plug it in, technically, they've probably voided the CE<br>
approval of their product, but then again, who gets their PC re-tested<br>
every time they install some new RAM.<br>
<br>
I have a friend who runs a small business who have been through CE<br>
approval a product that was essentially a zigbee node. I'll drop him a<br>
mail.<br>
