Warning
FOR
YOUR
SAFETY
PLEASE
READ
THE
FOLLOWING
TEXT
CAREFULLY
This appliance
is
supplied with a moulded three pin mains plug for your safety and conve-
nience.
A 3
amp
fuse
is
fitted
in
this plug.
Should the fuse need
to
be replaced please ensure that the replacement fuse has a rating of

1-5. Block Explanation
CPU
CPU is ARM60. This RISC type micro processer has 32-bit address and 32-bit data path.
MADAM supplies CPU with 12.5 MHz clock.
ROM
1 MB ROM stores the system management program. The ROM is connected to Slow bus and its data is
read by MADAM and MADAM arranges 8-bit data into 32-bit word and send it to CPU.
SAAM
32 KB SRAM is connected to Slow bus. Since Lithium battery backs up SRAM while power is down,
SRAM can retain data. It may be used to back up game data, for example.
DRAM/VRAM
DRAM and VRAM is used as main memory.
VRAM is dual-port memory. This means one port is used as normal DRAM and the other one is used to read
and write data simultaneously with the former port. Therefore, it is used as Frame Buffer which is required
fast access.
MADAM
MADAM is Address Engine. It includes OMA logic, CPU control logic, bus sharing logic and Cell Engine.
Aoscillator provides MADAM with 50 MHz clock, and MADAM divides it by two, and itprovides CLIO, CPU
and CD-ROM interface with 25 MHz clock.
CLIO
CLIO is Data Engine. It includes pixel decoding logic, 16-bit Digital Signal Processer and video interface
logic. With acrystal, CLIO oscillates 24.5454 MHz ( [g) or 29.5 MHz ( ~) clock and supplies MADAM with
24.54 MHz ( [g) or 29.5 MHz (~)and supplies Digital Color Encoder with 12.27 MHz ( [g) or 14.75 MHz
(~)-
Digital Color Encoder
CLIO supplies Digital Color Encoder with RGB data and some control signals. And Digital Color Encoder
modifies them into NTSC or PAL signals. It outputs both composit signal and Y/C signal.
Audio DAC
16-bit Audio DAC converts digital audio data from CLIO into analog audio data.
CLIO sends DAC data with serial communication manner.
CD-ROM interface
CD-ROM interface Gate Array is the interface between CLIO and both internal CD-ROM drive and External
drives which are connected through Expansion Port.

2. Checking Information
2-1. Handling Precautions for Traverse Deck
The laser diode in the traverse deck (optical pickup) may break down due to potential difference caused by static
electricity
of
clothes or human body.
So,
be
careful of electrostatic breakdown during repair of the traverse deck (optical pickup).
• Handling
of
traverse
deck
(optical pickup)
1.
Do not subject the traverse deck (optical pickup)
to static electricity as it is extremely sensitive to
electrical ~hock.
2.
To prevent the breakdown
of
the laser diode, an
antistatic shorting pin is inserted into the flexible
board (FPC board).
When removing
or
connecting the short pin, finish
the job
In
as short time as possible.
3.
Take care not to apply excessive stress
to
the
flexible board (FPC board).
4. Do not
tum
the variable resistor (laser power
adjustment). It has already been adjusted.
•
Grounding
for
electrostatic
breakdown
prevention
1. Human body grounding
Use the ant~static wrist strap to discharge the
static electricity from your body.
2.
Work
table grounding
Put a conductive material (sheet) or steel sheet on
the area where the optical pickup is placed, and
ground the sheet.
Caution:
The static electricity
of
your clothes
will
not be
grounded through the wrist strap. So, take care not
to
let your clothes touch the traverse deck (optical pickup).

2-2. Disassembly / Reassembly
Note:
Before disassembling, be sure to perform the following procedures first.
1. Remove the CD-ROM disk
if
it is inserted
in
the CD-ROM drive.
2.
Turn the power switch off.
3.
Disconnect the
AC
power cord.
4.
Remove the optional units.
Caution:
Please follow directions carefully.
