Legislation within countries around the world dictates high quality in both manufacturing and design procedures. With a commitment to on-going feature enhancement this policy has enabled us to maintain a strong compliance with world approvals, especially in the United States and European Union, where Federal Communication Commission (FCC) and harmonized (CE) standardization has led to the introduction of improved circuit design which maintains a high degree of RF immunity and the latest state of the art design. Such a level of voluntary commitment for approval makes us a market leader in quality and performance.
