All of the CD functions are controlled by the radio
buttons except for ejecting the magazine. Whenever a
CD magazine with CDs is loaded in the changer,
CHNGR will appear on the display. If the CD changer is
checking the magazine for CDs, CHNGR will flash on
the display until the changer is ready to play. When a
CD begins playing, the CD and track number will appear
on the display. The CD numbers are listed on the
front of the magazine.
