Abstract
Abstract A radio telecommunication apparatus to be used in a radio telecommunication system wherein one or more base units broadcast radio signals over a plurality of radio channels. The apparatus detects the availability of one or more radio channels and provides an indication representing operability of the apparatus in response to a change of the detected availability. The apparatus also provides an indication to a user in response to his request input or a call origination operation. Furthermore, the apparatus may provide an indication of which system is serving the apparatus in response to a received system identification signal.
