Selecting an audio program
If the station you are tuning in has multiple audio programs, “HD1”is indicated on the display.
If it only has one audio program, “HD” is indicated.
When the unit receives multicast channels, the multicast program number (HD2) is displayed to the right of the station name.
This function is not available for AM HD Radio stations because they cannot broadcast multicast channels.
If digital audio data cannot be received after the station is selected, or if the station signal is weak, the unit may not be able to receive the multicast channels.
If the station signal is weak, the digital audio of the multicast channel may cut out.
