 ## Playing
 Enter the frequency in MHz of the station you want to play and either click the triangular Play button on the toolbar, or just hit return. When the receiver attains synchronization, the pilot in the lower left corner of the status bar will turn green. It will return to gray if synchronization is lost. If the device itself becomes 'lost', the pilot will turn red to indicate an error has occurred (this is the theory, though I've yet to see this status message happen in practice). The synchronization process may take about 10 seconds, and the station will begin to play. This depends upon signal strength and whether it's relatively free from adjacent interference. After a short while, the station name will appear to the right of the frequency, and the available streams will show on a row of buttons just beneath the frequency entry. Clicking one of these buttons will change to that particular stream. Note: No settings other than stream may be changed while the device is playing.
