Abstract
Abstract A paging device for receiving information and including a test mode for determining the receiving characteristics of the device and a scan mode for scanning a frequency range within which the information exists in determining the frequency of the information. A receiver within the device for receiving information at a receiving frequency can be set at different receiving frequencies. A control unit sets the receiving frequency during the test mode to a predefined test frequency. The predefined test frequency is determined by the control unit without the device entering the scan mode.
