1、SERVICE MANUAL 1 Music production Center RadioFans.CN 收音机爱 好者资料库 SERVICE MANUAL 2 SAFETY INSTRUCTIONSINFORMATIONS 1. 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 are specified for con

2、formance with such regulations as those applying to spurious radiation. These must also be replaced only with the specified replacements. Examples : Noise blocking capacitors, noise blocking filters, etc. 3. Use specified internal wiring. Note especially : 1) Wires covered with PVC tubing 2) Double

3、insulated wires 3) High voltage leads 4. Use specified insulating materials for hazardous live parts. Note especially : 1) Insulation Tape 2) PVC tubing 3) Spacers (insulating barriers) 4) Insulation sheets for transistors 5) Plastic screws for fixing micro switches 5. When replacing AC primary side

4、 components (trans- formers, power cords, noise blocking capacitors, etc.), wrap the ends of the wires securely around the terminals before 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

5、 wires do not contact sharp edged or pointed 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 SERVICING After servicing, make measurements of leakage-current or resistance in

6、order to determine that exposed parts are acceptably insulated from the supply circuit. The leakage- current measurement should be done between accessible metal parts (such as chassis, ground terminal, microphone jacks, signal input/output connectors, etc.) and the earth ground through a resistor of

7、 1500 ohms paralleled with a 0.15 ? F capacitor, under the units normal working conditions. The leakage-current should be less than 0.5 mA rms AC. The resistance measurement should be done between accessible exposed metal parts and power cord plug prongs with the power switch (if included) “ON”. The

8、 resistance should be more than 2.2 M ohms. SYMBOLS FOR PRIMARY DESTINATION Unit destinations are indicated with letters as shown below.

24、ill not accept any user in put while a USB cable is connected) Note: The OS data can also be copied 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

25、Compact Flash card containing OS data. Insert a CF containing OS data into the MPC1000. Turn on the 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:

26、The MPC1000 can not be updated from a computer via USB directly updating is only possible using a CF 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. Cur

27、rently these modes are not supported in OS Version 1.06. Owner Name Mode Other F3/FOOTSW F6 Enter owner 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

28、 unit. Demo mode Hold down the Bank “D” button while powering on the unit. In this mode “Internal memory” 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 an

29、d on again. To turn off the Demo mode, hold down the Bank “D” button while powering on the unit. 1. 2. 3. 1. 2. 3. 4. SERVICE MANUAL 8 Test 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 OS A test program can be ins

30、talled on the MPC1000 by updating it with a Test OS. The Test OS must be copied to a 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 Progr

31、am list”. Note: Once the Test OS is installed, the unit will always start up using the 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 t

32、he test program on the PC Flash ROM MPC1K follow this procedure: 1. Turn off the MPC1000 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. MPC1000 TEST OS Starting DisplayStarting Display F1F1 F2F2 F3
