PRECAUTIONS
1. This unit does not operate independently. The unit must be used with a source unit that has a cable connec-
tion for CeNET wire bound (sold separately).
2. When playing 3" (8cm) CDs, use an adapter that conforms to the recommended CD standards or the adapter
included with the
mark. Refer to the adapter instruction manual concerning operation and loading 3"
(8cm) CDs in the adapter.
3.
The pickup, the heart of a player, is built in deep behind the door. Do not leave this door open for extended
periods to prevent dust adhering to the pickup.
When the inside of the car is very cold and the player is used soon after switching on the heater, dew may
form on the disc or optical parts of the player and proper playback may not be possible. If dew forms on the
disc, wipe it with a soft cloth. If dew forms on the optical parts of the player do not use the player for about
one hour and the condensation will disappear naturally to allow normal operation.
4. While the system is in play, do not plug or unplug the cables as this will cause damage.
5. Do not expose the magazine to direct sunlight, the car heater or other sources of strong heat. Replace the
CD magazine (CAA-122) with a new one if bent or otherwise damaged.
Caution
• ONLY use the magazine included with the CDC1255z or RDC1255z. For additional magazines, pur-
chase Clarion Model CAA122. Do not attempt to insert different style magazine into the CD changer
even if they fit into the magazine opening. Inserting other manufacturers' magazines or previous
Clarion 6 Pack style magazines into the CDC1255z or RDC1255z will cause damage to the mecha-
nism and void the warranty.
