A method and apparatus for reducing cross-talk in an oximeter. The electrically conductive adhesive is applied between the metal plate and the electrode of the piezoelectric body, and the metal plate and the piezoelectric body are subjected to heating and pressurization so that the carbon black aggregate is deformed, thereby hardening the electrically conductive adhesive. The memory further comprises a BIOS. The mobile unit generates a first value based on the first HFNs of established radio bearers wherein the first value is at least as great as the x most significant bits of each first HFN. The user interface may guide the user in the initiation of interactions between the digital camera and external devices such as television monitors, personal computers, and printers and may also provide feedback regarding the progress of these interactions.
