SAFETY INSTRUCTIONS
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.
:fr
...
...
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 inpuVoutput connectors, etc.) and the earth ground
through a resistor of 1500 ohms paralleled with a 0.15 F
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.

IV. SUPPLEMENTARY INFORMATION
[Update procedure]
===How to copy the
OS binary file to a CF card using a MPC2500 and a computer====
Below procedure will utilize the MPC2500 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. Copy/Download the OS data to a computer's hard disc drive and extract it's data.
2. Insert a Compact Flash card into the MPC2500.
3. Turn on the power of the MPC2500.
4. Go to Load mode, then press USB (F4 ).
5. Connect a USB cable between the computer and the MPC2500. (Display will change
from "Status=Not Connected" to "Status=Connected")
6. The CF in the MPC2500 will be mounted as a drive on the computer.
7. Copy the OS binary file to the CF in the MPC2500.
8. Disconnect the USB cable. (MPC2500 will not accept any user input 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 MPC2500 to a
computer.
====How to update the MPC2500====
MPC2500
is updated using a Compact Flash card containing OS data.
1. Insert a CF containing OS data into the MPC2500.
2. Turn on the power of the MPC2500 while pressing down the "Window" button.
3. ====MPC2500 OS UPDATE==== File: M25V100B.BIN (version information) will be
displayed
on the LCD screen.
4. To start the update process, press the "F6 (DO IT)" button. After the update process is
finished the MPC2500 will re-boot automatically.
Note: The MPC2500 can't
be updated from a computer via USB directly -updating is only
possible using a CF card.
-----------------SERVICEMANUAL-----------------
7

[Test program]
Test programs on the MPC2500 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 installed on the MPC2500 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 MPC2500.
The installation procedure is the same as for a normal OS update. For a description of the
test mode functions, refer to the "MPC2500 Test Program 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 MPC2.5K (AJ-771314J)]
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 MPC2.5K follow this procedure:
1. Turn off the MPC2500 and open the unit.
2. Insert the PC Flash MPC2.5K ROM into J110 on the CPU board.
3. Turn on the MPC2500 to start up the Test OS from the PC Flash ROM.
[Hidden modes]
The MPC2500 has the following hidden modes, which can be accessed by certain input
sequences or holding down a key while powering on the unit.
[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.
[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 "MPC2500". 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.
