7、ke sure that wires do not contact heat producing parts (heat sinks, oxide metal film resistors, fusible resistors, etc.). 7. Check that replaced wires do not contact sharp edged or pointed parts. 8. Also check areas surrounding repaired locations. 9. Make sure that foreign objects (screws, solder dr

8、oplets, etc.) do not remain inside the set. SAFETY CHECK AFTER SERVICING After servicing, make measurements of leakage-current or resistance in order to determine that exposed parts are acceptably insulated from the supply circuit. The leakage- current measurement should be done between accessible m

PRINCIPAL PARTS LOCATION SERVICE MANUAL 8 IV. OS Update

24、 Procedure OS Update Procedure OS Update procedure from USB The OS update can be made from the PC via the USB port. You must have the “OS loader software for MPC4000” besides the OS .bin file. The OS loader software includes the OS Loader.exe file, USB driver.inf file, and USB Driver.sys file. 1. In

25、stall USB Driver to your PC After all files are un-Zipped, place the USB Driver.inf and USB Driver.sys files into the same folder, e.g. Driver. Boot up the PC and MPC4000 complete and then connect the sampler to the PC using the USB cable. This prompts that the PC found the new device an d the new d

26、river is required. Refer it to the Driver folder you just created. The Driver software will be placed correctly and the MPC4000 is recognized properly. 2. OS update Double click on the OS Loader.exe icon and specify the OS .bin file. It will send the OS to the MPC4000. Caution After the update, be s

27、ure to initialize the MPC4000 by pressing the GLOBAL key, and then F6 (INITIAL) and F5 (DO IT) keys, before turning it off. OS update procedure from CD-R To update the OS from the CD-ROM, it requires the OS version later than V1.02 software installed on the MPC4000. You can update the OS from the CD

28、-ROM drive. Be sure to use the CD-ROM that contains the OS for the MPC 4000. You can create the OS disc by using your PCs CD-R/W function to write the “MPC4000.bin” file on to an ISO9660 CD-ROM disc. 1. Turn the MPC4000 on and insert the OS disc. 2. Press the LOAD key and select the MPC4000 OS file

29、(.bin file). 3. Press the F6 (DO IT) key and then the F6 (INSTALL) key. 4. The OS Update progress appears, i.e. the messages “Please wait ?.” and then “Upgrading of the Flash ROM was successful.” appear accordingly. 5. Press the F6 (Restart) key. Be sure to initialize the MPC4000 by pressing the GLO

30、BAL key, and then the F6 (INITIAL) and F5 (DO IT) keys, before turning it off. Writing Panel OS Program Change the position of the Short Pin P15 on the IO PCB to PROG side. The OS is automatically written to the Panel CPU RAM when the MPC4000 is switched on. Switch the unit off when the “Process com

31、pleted!” prompt message appeared and then replace the Short Pin to the original position. SERVICE MANUAL 9 Panel Test Mode To enter the Panel Test Mode, press the GLOBAL key while holding down the SHIFT key in the GLOBAL page F1 of the GLOBAL Mode. Moving the Q-link knobs changes the graphics accord

32、ingly. Tapping the PAD shows the amount of pressure applied on the bar graph. Switching the FOOT Pedal on/off changes the graphics accordingly. Turning the JOG wheel increases/decreases the value in the Data field. Pressing the key shows its name at the bottom of the screen. For those keys with the

33、LED, the LED is turned on/off. Pressing the F1 key stops the key test. After stopping the key test, pressing the mode key will abort the test mode. While the key test is stopped, pressing the SHIFT key and F6 key shows the A/D converted value of the Q-link/ PAD. CPU Board Test Mode The Test Mode of

34、the MPC4000 CPU Board is performed while the CPU board is mounted on the Z4/Z8 Sampler. When the Z4/Z8 is switched on after the MPC4000 CPU Board is mounted on the Z4/Z8 Sampler, the sampler is turned on with the MPC4000 screen. Install the Z4/Z8 OS using the “OS Loader” of “Boot Overwrite” type via

35、 the USB port. Similarly, when the CPU Board is mounted back on the MPC4000 after the Z4/Z8 OS is installed for the test, it boots up with the Z4/Z8 screen. Reinstall the MPC4000 OS using the “OS Loader” of “Boot Overwrite” type. Refer to the Z4/Z8 Service Manual for the operation details of the Tes
