To bring up the Flash Player and start the radio streaming, stand on the DVD (It will spin one turn around.) The radio will continue playing after you leave the stand. If you no longer need it, you can unload it by clicking the red (x) button to the right of the Controls Bar. By default, all avatars that are currently tuned to the radio will hear the same station. This allows for group listening where synchronisation between all users is wanted (for example in dance clubs.) However, there are times when you don't want other users to change the station you're listening to, and this is precisely what the Lock button does: It disconnects your radio from other users so you can listen to your favorite music without being interrupted. Of course, you can unlock the station anytime you wish to join back the group. You can hide the Radio Player by clicking the arrow on the right edge of the Controls Bar.
