The CD changer/player begins checking the CDs in the magazine which takes almost 20 seconds. The CD changer/player symbol will be displayed on the radio display to indicate the magazine is loaded. If the magazine is inserted without any CDs loaded, the symbol will not illuminate. (The CD changer/player symbol will flash during the CD check and initialization).

If the button is pressed during random play mode, the beginning of current track will be played.

While rewinding, sound can be heard at a reduced volume and the display will show elapsed track time to assist in locating specific passages.

When a new track is encountered during this search, it is briefly shown, the elapsed track time continues until the FF button is released. Then, the updated CD and track number will be displayed for ten seconds before the display changes to time of day.
9	Press DISC rocker button.	The DISC rocker button provides for forward and reverse CD selection. DISC directs the CD changer to find the beginning of the first available track on the next higher numbered available CD and resumes play from that point. DISC directs the CD changer to find the beginning of the first available track on the next lower numbered available CD and resumes play from that point. The CD number can be increased or decreased multiple times with wraparound at the lowest and highest available CD number.
IMPORTANT: If a CD in the CD changer/player has moisture on it or is accidentally loaded into the cartridge upside-down, initialization of that CD will not be completed. The upside-down CD will be skipped and the system will automatically select and play the next higher available properly loaded CD. If no CD can be played, "Err" will temporarily appear on the display and the system will return to the last played mode. Also, in random play mode, the "bad" CD is ignored as if no CD is in that slot.
