CDP-10 Initialization

The initialization process of the Premium 10500 has been developed, so that the application can play back most of the discs available on the market. Indeed, the re-tries are necessary to check for CDs, CD-Rs, CDRWs and HDCDs. It is also useful in case of slightly damaged discs or discs which are at the limit of the Red Book specifications.

Although the process may be a bit longer than expected (by the way the speed can not be changed), it allows to play back most of the discs. Else, we would have had complaints because some discs (CD-RW or damaged discs) would not be accepted by the application. Thus, the current process (number of re-tries, speed, time, ...) is a good compromise for a CD application in order to accept most of the discs, while keeping a good playability level (both are related during play back, hence it is important to have this process at initialization for disc acceptance).

As reported, dumping material is usually sufficient to reduce the noise at initialization. However, the mechanical design of the chassis has sometimes more influence on the amplification or reduction of the initialization noise (note that the re-tries are repeated only when no disc has been inserted ... ).

CDP- 10 SOFTWARE UPDATE

O VERVIEW__________________________________________________________________ _____________________

We have received and confirmed reports of two CDP-10 drawer-related issues that require your prompt attention.

The first is a minor, occasional hesitation while opening the drawer of the CDP -10. It occurs only when you open the drawer without letting the disc first come to a complete stop. It does not happen unless you open the drawer while the laser is near the middle or outer edge of the disc---playing higher track numbers, in other words. It appears to be repeatable with all the CDP -10s, but if you wait even a fraction of a second longer before opening the drawer, you might never see it.

The second is potentially more serious. If the standby button is pressed twice while the drawer is closing, the motor may continue to receive power even after the drawer has closed. The result is the motor will eventually burn out.

We have isolated the problems to software controlling the Philips drive and issued a new EPROM V1.6, for units in the field and made the necessary changes in all current production CDP-10s.

Neither problem has any relation to performance. And while the problems only occur under unusual circumstances, the potential for a motor failure lead s us to request that you install new EPROMS in all display and customer units as soon as possible.

We are providing EPROMS, a pulling tool and installation instructions, TSD0001, to all dealers and distributors who have taken delivery of at least one CDP-10.

CDP-10 SOFTWARE UPDATE

OVERVIEW______________________________________________________ ____________ _____________________

Software v1.7 supersedes v1.6 and should be installed in units having version v1.6 or lower. It is recommended that software in all customer and demonstration units be updated as soon as possible.

We are providing EPROMS and installation instructions, TSD0002, to all dealers and distributors who have taken delivery of at least one CDP-10.

Contact Classé if you are holding any CDP-10s in A-stock inventory.

CDP- 10 SOFTWARE UPDATE

KIT__________________________________________________________________ ______________________________

The upgrade kit consists of one EPROM (28 pin IC) and one IC extractor tool.

PROCEDURE________________________________________________________________________________________

CDP-10 EPROM REPLACEMENT PROCEDURE

• It is preferable to perform this upgrade at a static controlled workstation. ESD handling precautions should be observed.

1- Ensure that the AC power cord is disconnected. 2- Remove unit cover by first removing all eight Phillips head screws then simply lifting the cover. 3- Locate EPROM as indicated in figure 1. The component identifier is “U503.” 4- Remove the old EPROM from the socket by placing the supplied IC extractor’s hooks under each

end of the EPROM, squeezing gently, and pulling the EPROM straight up while holding the chassis firmly on your work table.

5- The new version EPROM and the socket both have a “D” shaped notch at one end; these must

align to ensure proper pinout connection when inserting the new EPROM.

6- Align the notches of both components and ensure that each pin of the EPROM is positioned to

properly insert into the corresponding receptacle of the socket. Be careful not to touch the pins as the EPROM is static sensitive. Press gently and evenly on both ends of the EPROM until it is fully inserted.

7- Replace unit cover and eight Phillips head screws. 8- Power up the CDP-10 and test.

5- The new version EPROM and the socket both have a “D” shaped notch at one end; these must

align to ensure proper pinout connection when inserting the new EPROM.

6- Align the notches of both components and ensure that each pin of the EPROM is positioned to

properly insert into the corresponding receptacle of the socket. Be careful not to touch the pins as the EPROM is static sensitive. Press gently and evenly on both ends of the EPROM until it is fully inserted.

7- Replace unit cover and eight Phillips head screws. 8- Power up the CDP-10 and test.
