This Report sets out common technical and non-technical parameters for short-range radiocommunication devices (SRDs) and widely recognized approaches for managing their use on a national basis. When using this Report it should be remembered that it represents the most widely accepted views but it should not be assumed that all given parameters are accepted in all countries. It should also be remembered that the pattern of radio use is not static. It is continuously evolving to reflect the many changes that are taking place in the radio environment; particularly in the field of technology. Radio parameters must reflect these changes and the views set out in this Report are therefore subject to periodic review. Moreover, almost all administrations still have national regulations. For these reasons, those wishing to develop or market SRDs based on this Report are advised to contact the relevant national administration to verify that the position set out herein applies.
