... FCC Labeling Requirements The A2500R24A and A2500R24C modules have been labeled with their own FCC ID number and if the FCC ID is not visible when the module is installed inside another device, then the outside of the finished product into which the module is installed must also display a label referring to the enclosed module. This exterior label can use wording such as the following: A2500R24x – ...

... Temperature Range 3.3. Pin Out The A2500R24C and A2500R24A radio modules share a common pin-out and foot print, that is also shared by Anaren modules using other frequencies -- thus enabling easy changeover from one to another, e.g. if changing the frequency, antenna scheme, or adaptive antenna tuning is desired. Below the common footprint are shown. ...
