COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED LINE WITH MARK 0 ON THE SCHEMATIC DIAGRAMS AND IN THE PARTS LIST ARE CRITICAL TO SAFE OPERATION. REPLACE THESE COMPONENTS WITH SONY PARTS WHOSE PART NUMBERS APPEAR AS SHOWN IN THIS MANUAL OR IN SUPPLEMENTS PUB- LISHED BY SONY. Notes on chip component replacement - Never reuse a disconnected chip component. - Notice that the minus side of a tantalum capacitor may be dam- aged by heat. Flexible Circuit Board Repairing - Keep the temperature of the soldering iron around 270 ËšC dur- ing repairing. - Do not touch the soldering iron on the same conductor of the circuit board (within 3 times). - Be careful not to apply force on the conductor when soldering or unsoldering. UNLEADED SOLDER Boards requiring use of unleaded solder are printed with the lead- free mark (LF) indicating the solder contains no lead. (Caution: Some printed circuit boards may not come printed with the lead free mark due to their particular size) : LEAD FREE MARK Unleaded solder has the following characteristics. - Unleaded solder melts at a temperature about 40 ËšC higher than ordinary solder. Ordinary soldering irons can be used but the iron tip has to be applied to the solder joint for a slightly longer time. Soldering irons using a temperature regulator should be set to about 350 ËšC . Caution: The printed pattern (copper foil) may peel away if the heated tip is applied for too long, so be careful! - Strong viscosity Unleaded solder is more viscous (sticky, less prone to flow) than ordinary solder so use caution not to let solder bridges occur such as on IC pins, etc. - Usable with ordinary solder It is best to use only unleaded solder but unleaded solder may also be added to ordinary solder. NOTES:- The recorded music is limited to private use only. Use of the music beyond this limit requires permission of the copyright holders. - Sony is not responsible for music files that are not saved on your computer due to unsuccessful recording from CD or music downloading. Other features - Compact size, light weight. - Skip-proof: you can enjoy uninterrupted enjoyment of music during physical activities such as jogging or commuting. - Approximately 10 hours of continuous playback with a rechargeable nickel hydride battery. - Recordable time: up to 60 min., 80 min., 120 min.**, on the supplied 64MB MagicGate Memory Stick. - Backlight LCD screen: song titles and artist names can be displayed. - High speed data transfer using the supplied USB cable. - OpenMG Jukebox software enables you to record compact discs using the ATRAC3 format (high sound quality, high compression) to the hard drive. * The copyright protection technology of Network Walkman conforms to the SDMI (Secure Digital Music Initiative) specifications. **Differs according to the bit rate when recording. In this case, the figures for the recordable time are when recording on a 64MB MagicGate Memory Stick at 132kbps, 105kbps, and 66kbps. ATTENTION AU COMPOSANT AYANT RAPPORT Ã- LA SÉCURITÉ! LES COMPOSANTS IDENTIFIÉS PAR UNE MARQUE 0 SUR LES DIAGRAMMES SCHÉMATIQUES ET LA LISTE DES PIÈCES SONT CRITIQUES POUR LA SÉCURITÉ DE FONCTIONNEMENT. NE REMPLACER CES COM- POSANTS QUE PAR DES PIÈCES SONY DONT LES NUMÉROS SONT DONNÉS DANS CE MANUEL OU DANS LES SUPPLÉMENTS PUBLIÉS PAR SONY. Ver 1.1

3 NW-MS9 - NOTE FOR REPLACING THE EEPROM (IC6002) In case of replacing the EEPROM (IC6002) when repairing this set, it is necessary to write the setting for destination. When replacing the EEPROM (IC6002), write the setting for destination, referring to 4. TEST MODE, Items to Check in the Test Mode, 3-2. Writing Destination. - Replacement of MBM29LV400BC-90PBT (IC5000), HY62UF16201ALLF (IC5600), CXD9534BGG (IC7001) and CXD1859GA (IC8000) used in this set requires a special tool. - To check the operation when the MAIN board and SUB board are removed, check it after connecting CN100 on the MAIN board and CN200 on the SUB board with the servicing jig (relay board between the MAIN board and SUB board) as shown below.
