When a recording device is connected to a power source and a main power is supplied, position information of the recording device is obtained by using GPS satellites. A region where the recording device is installed is decided based on the obtained position information. Channel information appropriate for the decided region is read out from a storage medium such as a memory, and a tuner of the recording device is set automatically using the read channel information thus read. Additionally, when the position information is obtained, it is decided whether or not the position where the recording device is installed is within a predetermined distance from a boundary between regions. If it is adjacent to other region, a plurality of region codes are read out, and a request for selecting one to perform the channel setting is displayed using a display panel or an OSD function so that the selection can be received.
