Helpful Tips 1. If the Internet Radio keeps re-buering radio station:

The Internet Radio is streaming the data from the radio station via your broadband connection, if there is a high error rate on your broadband connection, or the connection is intermittent, then it will cause the Internet Radio to pause until the connection is re-established and it has received enough data to start playing again. If your Internet Radio keeps stopping, please check the DSL modem to ensure that the Broadband line is not suering a high error rate or disconnections. If you are experiencing these problems, you will need to contact your broadband supplier. 2. What is Buering?

When playing a stream, the Internet Radio/Media player, downloads a small amount of the stream before it starts playing. This is used to ll in any gaps in the stream that may occur if the internet or the wireless network is busy. The Internet Radio streams music data from the PC while you are listening. If a stream gets blocked or experiences Internet congestion while transferring it may stop/interfere with the quality of play. If this happens, check your internet connection speed- it must be faster than the speed of the streams. 3. My Radio is working but some stations cannot be played. The problem may be due to one or more of the followings:

a. The radio station is no longer broadcasting. b. The radio station has reached the maximum allowed number of simultaneous listeners. c. The radio station has changed the stream arrangement and the link is no longer valid. d. The radio station is not broadcasting at the time of the day (not all stations are broadcasting 24 hours throughout the day). e. The Internet connection between your radio and the radio station server is too slow or unstable to support the data rate of the broadcast.
