Mazda 2007 Zoom-Zoom Owner's Manual page 233

A new CD may have rough edges on
l
its inner and outer perimeters. If a disc
with rough edges is used, proper
setting will not be possible and the CD
player/In-dash CD changer will not
play the CD. In addition, the disc may
not eject resulting in a malfunction.
Remove the rough edges in advance by
using a ball-point pen or pencil as
shown below. To remove the rough
edges, rub the side of the pen or pencil
against the inner and outer perimeter of
the CD.
When driving over uneven surfaces,
l
the sound may jump.
The CD player/In-dash CD changer has
l
been designed to play CDs bearing the
identification logo as shown. No other
discs can be played.
Use discs that have been legitimately
l
produced. If illegally-copied discs such
as pirated discs are used, the system
may not operate properly.

Be sure never to touch the signal
l
surface when handling the CDs. Pick
up a CD by grasping the outer edge or
the edge of the hole and the outer edge.
Do not stick paper or tape on the CD.
l
Avoid scratching the reverse side (the
side without a label). The disc may not
eject resulting in a malfunction.
Dust, finger smudges, and dirt can
l
decrease the amount of light reflected
from the signal surface, thus affecting
sound quality. If the CD should
become soiled, gently wipe it with a
soft cloth from the center of the CD to
the edge.
