A communication system and method are disclosed for allowing a consumer to place wireless calls over their wireless communication device from telephones connected through-out their location. Rename logic supports renaming for both partial-bit accesses and bulk-bit accesses to bits of the register. In some embodiments, the cleaning solution provides low residual rate of proteins, low residual rate of lipids, desirable within-batch repeatability in clinical testing, low level of cross-contamination, and low level of reactant deposit after cleaning, without affecting test results of the biochemical analyzer. Also, operation of a service switch for the actuator may be checked relative to its state.
