To load more than one CD but less than six, complete
Steps 1 through 3. When finished loading CDs, the
radio will begin to play the last CD loaded.
When a CD is inserted, the CD symbol will appear on
the display. If more than one CD has been loaded,
a number for each CD will appear on the display. If you
select an equalization setting for your CD, it will be
activated each time you play a CD.
As each new track starts to play, the track number will
appear on the display.
Playing a Specific Loaded CD
For every CD loaded, a number will appear on the
display. To play a specific CD, first press the CD AUX
button, then press the numbered pushbutton that
corresponds to the CD. A small bar will appear under
the CD number that is playing and the track number
will appear.
If an error appears on the display, see "CD Messages"
later in this section.

LOAD CD Z (Eject): Press the CD eject side of
this button to eject a CD(s). To eject the CD that
is currently playing, press and release this button.
To eject multiple CDs, press and hold this button for
two seconds. You will hear a beep and the indicator light
will flash to let you know when a CD is being ejected.
REMOVE CD will appear on the display. The CD can be
removed. If the CD is not removed, after 25 seconds,
the CD will be automatically pulled back into the player.
If the CD is pushed back into the player, before the
25 second time period is complete, the player will sense
an error and will try to eject the CD several times
before stopping.
Do not repeatedly press the CD eject button to eject a
CD after trying to push it in manually. The player's
25-second eject timer will reset at each press of eject,
causing the player to not eject the CD until the
25-second time period has elapsed.
Once the player stops and the CD is ejected, remove
the CD. After removing the CD, push the PWR knob off
and then on again, or wait for the system to reset.
This will clear the CD-sensing feature and enable CDs
to be loaded into the player again.
