#INFORMATIONS
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 conformance 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 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 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 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 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 1500 ohms paralleled with a 0.15 µF
capacitor, under the unit’s 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 resistance should be
more than 2.2 M ohms.

MAKE YOUR CONTRIBUTION TO PROTECT THE
ENVIRONMENT
Used batteries with the ISO symbol for recycling as
well as small accumulators (rechargeable batteries),
mini-batteries (cells) and starter batteries should not
be thrown into the garbage can.
Please leave them at an appropriate depot.
PRECAUTIONS FOR LITHIUM BATTERY
The lithium battery may explode when
incorrectly replaced.
[OBSERVE THE FOLLOEING WHEN REPLACING]
• Replace with the same make and type or equivalent recom
mended by manufacturer.
• Place battery in correct polarity.
• Do not short the terminals.
• Do not charge battery.
• Do not dispose of battery in fire.

IV. OS Update 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. Install 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 driver 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 sure 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-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 PC’s 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 (.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 GLOBAL 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 completed!”prompt message appeared and then replace the Short Pin to the
original position.

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 accordingly.
•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 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 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 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 Test Mode for the CPU Board.
