When a game apparatus detects a double-touch in an area other than an area where an enemy character is displayed, the game apparatus causes a player character to perform a forward roll motion. The indicators identify different codings to be used for different corresponding bands in the wireless channel. These corresponding components are then used by a source-determination arrangement to infer the presence of at least one sound source and to determine the azimuth location of this source within the audio field. The assembly comprises a common power terminal block that makes the electrical connection by clamping the output side connection strips of the first electrical device with the input side connection strips of the second electrical device, thus providing a mechanical attachment between the two electrical devices. The user’s device then accesses the broadcast streaming program and playback begins.
