Hummer H3. Manual — part 1204

Handle CDs carefully. Store them in their original cases or other protective cases and away from
direct sunlight and dust. The CD player scans the bottom surface of the disc. If the surface of a
CD is damaged, such as cracked, broken, scratched or wrinkled labeling, the CD will not play
properly or not at all. If the surface of a CD is soiled, take a soft, lint free cloth or dampen a
clean, soft cloth in a mild, neutral detergent solution mixed with water and clean it. Make sure the
wiping process starts from the center to the edge. Do not touch the bottom side of a CD while
handling it. This could damage the surface. Pick up CDs by grasping the outer edges or the edge
of the hole and the outer edge.

Care of the CD Player

The use of CD lens cleaners for CD players is not advised, due to the risk of contaminating the
internal lens of the CD optics with lubricants.

Stuck CDs

Interrupting the battery power by pulling the fuse will sometimes release a stuck CD. If a CD is
stuck and removed, inspect it for warps, cracks, etc. If the CD is damaged, do not replace the
radio.

Labeling CDs

Paper labels can eventually warp and wrinkle and this will cause the disc to jam inside the CD
player. Try labeling the top of the discs with a soft magic marker instead.
