A wireless communication terminal includes a radio frequency transceiver and a baseband processing circuit, which is arranged to detect an indication of a rate of movement of the terminal. The solar cell comprises a solar cell substrate having a light receiving frontside and a backside comprising base and emitter regions. The apparatus further includes a sensor electrically coupled with the plurality of switches, wherein the sensor monitors the change of state of each switch to indicate that the respective conductive pins are properly mated with the circuit board.
