A mobile radio terminal includes a system clock having a controller, a frequency generator for outputting a clock signal and a temperature sensor for detecting an operating temperature of the frequency generator. The protection switch includes a wavelength selective switch coupled to the two-fiber optical channel protection ring. A plurality of LCD’s each discretely associated with a corresponding camera are mounted within the vehicle passenger compartment at a location that is readily observable by the vehicle driver. If the battery voltage signal is above a minimum reference value, the battery voltage signal will be analyzed to ensure that neither voltage spiking nor a no load change condition caused the anomaly. The first reservoir provides for the containment and storage of at least a first component and the second reservoir provides for the containment and storage of at least a second component. Individual shaped charge units and cooperative fusing are assembled in a light weight inner loading tube having an alignment collar to secure the angular and axial position of the loading tube relative to the transition collars.
