Wiring and Additional Improved Features

The 1991 model year radio features an improved wiring connection with integral CD data cable mounting. It is also equipped to accept the new 50 ohms antenna connector.

Although radios of both Pioneer and Alpine manufacture are identical in appearance in their installed positions, the radio manufacturer may be identified (in the dot-matrix display) by pressing the "Prog" and "-" keys simultaneously.

Important
Note: Both CD changers are designed to give years of trouble-free service.
However, improper maintenance of compact discs can comprise the reliability of the changer. It is therefore important to observe the following cautions:

1. Never use 3 inch discs in the changer (even with an adapter). Use only 5 inch (12 cm) compact discs.
2. Never affix labels, paper, or tape to compact discs.
3. Never load a cracked, bent, or otherwise damaged disc into the magazine.
4. Never apply any foreign substance (record cleaning spray, anti-static agents, marking ink, etc.) to a compact disc. If the disc should become soiled, gently wipe the surface with a soft, dry, lint-free cloth, wiping from the center of the disc to the edge.
