Parts identified by the ? symbol are critical for safety.Replace them only with the parts number specified.2. In addition to safety, other parts and assemblies arespecified for conformance w

2、ith such regulations as thoseapplying to spurious radiation.These must also be replaced only with the specifiedreplacements.Examples : Noise blocking capacitors, noise blocking filters,etc.3. Use specified internal wiring. Note especially :1) Wires covered with PVC tubing2) Double insulated wires3)

3、High voltage leads4. Use specified insulating materials for hazardous live parts.Note especially :1) Insulation Tape2) PVC tubing3) Spacers (insulating barriers)4) Insulation sheets for transistors5) Plastic screws for fixing micro switches5. When replacing AC primary side components (trans-formers,

4、 power cords, noise blocking capacitors, etc.),wrap the ends of the wires securely around the terminalsbefore soldering.6. Make 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

5、orpointed parts.8. Also check areas surrounding repaired locations.9. Make sure that foreign objects (screws, solder droplets,etc.) do not remain inside the set.SAFETY CHECK AFTER SERVICINGAfter servicing, make measurements of leakage-current orresistance in order to determine that exposed parts are

6、acceptably insulated from the supply circuit. The leakage-current measurement should be done between accessiblemetal parts (such as chassis, ground terminal, microphonejacks, signal input/output connectors, etc.) and the earth groundthrough a resistor of 1500 ohms paralleled with a 0.15 ? Fcapacitor

7、, under the units normal working conditions.The leakage-current should be less than 0.5 mA rms AC. Theresistance measurement should be done between accessibleexposed metal parts and power cord plug prongs with thepower switch (if included) “ON”. The resistance should bemore than 2.2 M ohms.SYMBOLS F

21、ORMATIONUpdate procedure =How to copy the OS binary file to a CF card using a MPC1000 and a computer= Below procedure will utilize the MPC1000 as a Compact flash writer. Required Equipment : Compact Flash (CF), Computer with USB mass storage class support (Windows XP/ME/2000 or Mac OSX, OS9.x) 1. Co

22、py/Download the OS data to a computer s hard disc drive and extract it s data. 2. Insert a Compact Flash card into the MPC1000. 3. Turn on the power of the MPC1000. 4. Go to Load mode, then press USB (F4). 5. Connect a USB cable between the computer and the MPC1000. (Display will change from “Status

23、=Not Connected ” to “Status=Connected ”) 6. The CF in the MPC1000 will be mounted as a drive on the computer. 7. Copy the OS binary file to the CF in the MPC1000. 8. Disconnect the USB cable. (MPC1000 will not accept any user in put while a USB cable is connected) Note: The OS data can also be copie

24、d to a Compact Flash card using any other Compact Flash card reader/writer. In this case it is not necessary to connect the MPC1000 to a computer. =How to update the MPC1000= MPC1000 is updated using a Compact Flash card containing OS data. Insert a CF containing OS data into the MPC1000. Turn on th

25、e power of the MPC1000 while pressing down the “Window” button. To start the update process, p ress the “REC” button. After the update process is finished the MPC1000 will re- boot automatically.Note: The MPC1000 can not be updated from a computer via USB directly updating is only possible using a C

26、F card. =Hidden model=( Note: V1.06 is not supported.) The MPC1000 has the following hidden modes, which can be accessed by certain input sequences or holding down a key while powering on the unit. Currently these modes are not supported in OS Version 1.06. Owner Name Mode Other F3/FOOTSW F6 Enter o

27、wner name in the startup screen, “Owner Name” will be displayed. Initialize parameter Hold down the ERASE button while powering on the unit. Memory Check Hold down the PLAY button while powering on the unit. Demo mode Hold down the Bank “D” button while powering on the unit. In this mode “Internal m

28、emory” on the Save page can not be selected . In the startup screen “Demo” will be displayed instead of “MPC1000”. Once demo mode has been activated it will remain active even if power is turned off and on again.To turn off the Demo mode, hold down the Bank “D” button while powering on the unit. 1.2

29、.3. 1.2.3. 4.RadioFans.CN 收音机爱 好者资料库SERVICE MANUAL8Test program Test programs on the MPC1000 can be run either using a Test OS or a JIG PC Flash Rom. Running the test Program using a Test OSA test program can be installed on the MPC1000 by updating it with a Test OS. The Test OS must be copied to a

30、CF card from which it will be written to the Flash ROM of the MPC1000. The installation procedure is the same as for a normal OS update. For a description of the test mode functions, refer to the “MPC1000 Test Program list”. Note: Once the Test OS is installed, the unit will always start up using th

31、e Test OS, until the regular OS is re-installed. Running the test Program using a JIG PC Flash ROM MPC1K (AJ - 771312J) The PC Flash ROM is used during repair for the testing jig and boot block recovery. To access the test program on the PC Flash ROM MPC1K follow this procedure: 1. Turn off the MPC1

32、000 and open the unit. 2. Insert the PC Flash MPC1K ROM into J110 on the CPU board. 3. Turn on the MPC1000 to start up the Test OS from the PC Flash ROM.
