Apparatus is for reception and transmission of data signals at one or more user locations. The data signals are received from and transmitted to remote locations typically via a satellite or cell phone transmission system. The operating condition of the apparatus at the user location is selectively adaptable such as to take into account the particular format in which the data signals are received or are to be transmitted to thereby allow the apparatus to be used in different locations and adapted for use at the time of installation or at a time after installation with no, or minimal, intervention or skilled technical personnel attendance being required at the user location to allow the operation of the apparatus to be adapted.
