Disc Select (SIDE Button)

For CD changer applications (U1S), the radio PROG button is a non-latching momentary contact control. The PROG button serves a dual function with the radio preset button # 5. It functions as a disc select when you are in the CD changer mode. Each momentary button press increases the disc number by one, starting from the presently selected disc or at the lowest numbered disc. if a disc has not been previously selected. The disc count wraps back to the first available disc after the last disc is selected. Preset button # 6 is a hidden button that decreases the disc number by one. Only the cartridge slot numbers with discs installed are available for selection.

During the selection process the following actions occur:
^ The disc number displays
^ Track number 1 is displayed
^ The audio mutes

The disc and track numbers always display simultaneously.
