An objective of the present invention is to present an optimal information system in accordance with build requisites which a user desires. A baseband processing circuit includes processing components that are coupled to receive and process the first and second downconverted signals so as to extract first and second data from the signals. Latch members extend from the shield that include catches for engaging mating catches on the body for holding the body in the extended position. The electronically readable media includes random access memory, read only memory, magnetic media, optical media, magneto-optical media, CDROM, digital video disk, hard disk, a remote computer memory storage location accessible via an electronic network such as a telephone system or a computer network, or any other electronically readable media method.
