The memory card reader has been tested with many of the prod-
ucts available on the market. However, in isolated cases it is
possible that individual memory cards may not be recognized.
Inserting a memory card
– Slide the memory card in the card reader slot with the
label side up (contact surface down) ⇒ fig. 37. The
angled corner of the memory card must point toward the
front right.
– Then push the memory card into the slot until you feel it
click into place. The memory card is flush with the area
around it. When the CD/SD function is activated, the
system automatically changes to the memory card
reader and begins playing.
If a memory card has been inserted and not played, the data from
the ID3/WMA tags are read in the background. If you start playback
of the memory card immediately, the ID3/WMA tag data are
displayed for the track currently being played.
