CD CHANGER LOADING PROCEDURES

BECAUSE OF DIFFERENCES IN CD CHANGER LOADING PROCEDURES, SOME CONFUSION EXISTS REGARDING THIS ISSUE. ALTHOUGH CORRECT LAODING PROCEDURES ARE INCLUDED WITH EACH CHANGER'S OWNER'S MANUAL, OFTEN THIS INFORMATION IS NOT AVAILABLE TO THE DEALER SERVICE PERSONNEL.

VERIFY PROPER LOADING WHEN EVALUATING CUSTOMER CONCERNS OF "CD INOPERATIVE".

DELCO ELECTRONICS PRODUCT TYPE LOADING PROCEDURE

RADIO W/INTERGRAL CD LABEL SIDE UP 6 DISC CHANGER (LLAI) LABEL SIDE UP 10 DISC CHANGER (FMI) LABEL SIDE UP

12 DISC CHANGER (LLAI) LABEL SIDE DOWN

IMPORTANT: FAILURE TO LOAD MAGAZINE/PLAYER CORRECTLY WILL DISABLE THE OPERATION.

NOTE THAT ONLY THE 12 DISC CHANGER IS TO BE LOADED WITH THE LABEL SIDE DOWN.

CD CLEANERS

AVOID USE OF COMMERCIALLY AVAILABLE CD CLEANERS.

THE USE OF CD CLEANERS IS NOT RECOMMENDED AND CAN DAMAGE THE PLAYER'S CD MECHANISM.

UNLIKE CASSETTE TAPE HEADS, WHICH MUST BE CLEANED REGULARLY, CD MECHANISMS DO NOT ACCUMULATE RESIDUE ON THE OPTICS DURING NORMAL USE. THIS IS BECAUSE THERE IS NO ACTUAL CONTACT BETWEEN THE DISC SURFACE AND THE OPTIC LENS. THUS, ROUTINE CLEANING IS NOT NEEDED TO MAINTAIN PEAK FIDELITY.
