Abstract
A radio communication device, suitable for use in a portable computer, is capable of operating at any one of a set of common frequencies which are legally permissible in all countries (or a set of countries) and at any frequency on which it detects that a transmission of its own type is being used for a transmission from another device. Thus, users can legally operate the device in different countries, while manufacturers can obtain certification for use in those countries. If the user attempts to select a frequency which is not one of the common frequencies nor detected by transmission, an indication that such frequency is not available is provided to the user.
