CD Pro 2 is backward compatible with CDM 12 Industrial/CD Pro players: having same electrical connections and same communication interface. However, the optical pick-up and the control PCB are not interchangeable. Mechanically they are very similar.

Q: How long does it take to replace the optical pickup?
Depending on your skill level servicing small electronic devices, all procedures shouldn't take more than 30 minutes.

Q: What lubrication should I use?
Factory recommends using Tribol Molub-Alloy 9890-2 lubricant. It is manufactured by Castrol Germany and is quite uncommon. We do have limited stock of the Tribol. The recommended substitute is Krytox GLP-204 by Dupont. Click on this link for recommended maintenance by the factory.

Q: I replaced the optical pickup and the unit still does not work.
Does it have the same symptoms as before you started to service the unit? If so, the problem is not with the optical pick-up itself. We recommend replacing the turntable motor. It is extremely difficult to trouble shoot a bad motor. Also make sure you did not use a wrong optical pickup. CDM12 & CD Pro optical pickups are not compatible with CD Pro 2 optical pickups.

Q: Is there any modification necessary to repair the unit?
No. This is the advantage of repairing the CD player, you do not have to modify or install any non-factory players into your jukebox and therefore, there is no need to carry several different CD players to fix your jukeboxes.

Q: What is the most common problematic part on the CD player?
From our experience we found the optical pickup is the most troublesome. It is best to replace it at any sign of trouble. We are also recommending to replace the turntable motor, particularly on CD Pro 2 players.

Q: What tools do I need to repair the CD player?
You will need minimum No. 6 and No. 10 torx drivers, small flat screwdriver, and a small wire cutter.

Q: Should I perform regular maintenance of the CD player?
Factory recommends regular lubrication. See the enclosed link for maintenance instructions.

Q: Is there any adjustment or calibration necessary to repair the unit?
No. All required adjustments and calibrations were already performed on all new OPUs at the factory.
