Development of the technology and the design of the circuitry were done with minimum number of components as possible, so as to make the product totally cost-effective, and to reduce the component failure rate. Further, emphasis was given to the use of only indigenous components, which are freely available in the Indian market; for the development of the circuitry. This was done with a vision to avoid bottlenecks in all stages of production and marketing. For the development of this product, usage of customized components/parts were kept at the minimum, in order to ensure that the mass production process does not get hampered, and the "economies of scale" is achieved for the manufacturer.
