CARE AND MAINTENANCE

CD Player

The following guidelines will help you extend the life of your CD player:
1. When cleaning the vehicle interior, do not get water or cleaning fluids on the unit.
2. The CD player will not operate properly in extreme hot/cold or under damp conditions. In
case of such conditions, wait until the vehicle interior reaches a normal temperature or
any condensation on the disc player lens has evaporated before using the player.
3. Never insert anything other than round 5” CDs into the player. Attempting to insert CDs of
other sizes (even with an adaptor) will cause damage not covered by the warranty.
4. Always remove the CD when the player is not is use.
5. The unit is designed with a vibration dampening CD mechanism to minimize interruption
of disc play due to normal vibration in a moving vehicle. However, occasional sound skips
may occur when driving on very rough roads. This will not scratch or damage the disc,
and normal play will resume when the rough conditions cease.

Compact Discs

CD-R and CD-RW Capability
Depending on media type and method of "recording/burning", some CD-R/RWs may be
incompatible with this unit. After "recording/burning", the session must be closed. Please refer
to your software's recommended procedures for closing a disc/session. Review your recording
software to familiarize yourself with the correct "recording/burning" procedures. We
recommend using the latest versions of ROXIOTM or NEROTM burning software.
In addition, this unit will only recognize the CDDA (Compact Disc Digital Audio), .MP3
and .WMA formats "recorded / burned" onto a CD-R/RW. This unit does not support .WAV,
.OGG or other formats.
CD Care and Handling
Dirt, dust, scratches and warpage can cause skips in the playback and deterioration of sound
quality. Please follow these guidelines to take care of your compact discs.
1. Carefully wipe fingerprints, dust and dirt from the disc’s playing surface with a soft cloth.
Wipe in a straight motion from the inside to the outside of the disc.
2. Never use chemicals such as record sprays or household cleaners to clean CDs, as they
can irreparably damage the disc’s surface.
3. Discs should be kept in their storage cases when not in use.
4. Do not expose discs to direct sunlight, high temperatures or high humidity for long
periods.
5. Do not stick paper, tape or CD labels on disc surfaces, as internal damage may
occur.
