WARNINGS
FOR YOUR SAFETY PLEASE READ THE FOLLOWING TEXT CAREFULLY
This appliance is supplied with a moulded three pin mains plug for your safety and convenience.
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 3
amps and that it is approved by ASTA or BSI to BS 1362.
Check for the ASTA mark or the BSI mark on the body of the fuse.
If the plug contains a removable fuse cover you must ensure that it is refitted when the fuse is
replaced.
If you lose the fuse cover the plug must not be used until a replacement cover is obtained.
A replacement fuse cover can be purchased from your local Panasonic Dealer.
IF THE FITTED MOULDED PLUG IS UNSUITABLE FOR THE SOCKET OUTLET IN YOUR
HOME THEN THE FUSE SHOULD BE REMOVED AND THE PLUG CUT OFF AND DISPOSED
OF SAFELY.
THERE IS A DANGER OF SEVERE ELECTRICAL SHOCK IF THE CUT OFF PLUG IS INSERTED
INTO ANY 13 AMP SOCKET.
If a new plug is to be fitted please observe the wiring code as shown below.
If in any doubt please consult a qualified electrician.
Important
The wires in this mains lead are coloured in accordance with the following code:
Blue: Neutral
Brown: Live
As the colours of the wires in the mains lead of this apparatus may not correspond with the
coloured markings identifying the terminals in your plug, proceed as follows:
A S A
The wire which is coloured Blue must be connected to the terminal which is marked with
the letter N or coloured BLACK.
The wire which is coloured Brown must be connected to the terminal which is marked
with the letter L or coloured RED.
Under no circumstances should either of these wires be connected to the earth terminal of the
three pin plug, marked with the letter E or the Earth Symbol .
The mains plug on this equipment must be used to disconnect the mains power.
Please ensure that a socket outlet is available near the equipment and shall be easily
accessible.
How to replace the fuse
Open the fuse compartment with a screw
driver and replace the fuse.
Warnings
This equipment is not designed for connection to an IT power system.
(An IT system is a system having no direct connections between live parts and Earth; the exposed
conducive parts of the electrical installation are earthed.
An IT system is not permitted where the computer is directly connected to public supply systems in the
U.K.)
Disconnect the mains plug from the supply socket when the computer is not in use.
This equipment is produced to BS800/1983.

3.Technical Information
3.1 System Overview
3.1.1 System Configuration
The main system is made up of a Main board, a SUB board, a LED board, a PAD board and a LID board.
The CPU operates at 1.6V, 1.35V(core)/2.5V; the main memory at 3.3V; the core logic at 3.3V/5V; and the
other main chips at 3.3V.
3.1.2 Power Supply System
The power supply used by the Main board is generated on the Main board based on the voltage from the AC adapter.
Power Supply System Description On mode
VC system (VC5, VC3, VC25, VC18,
VC16, VC15)
CPU and logic power supply ON OFF OFF
Suspend
mode
VB system (VB5, VB3) Logic power supply ON ON OFF
VA system (VA3) PMC power supply ON ON ON
VPP system (VPP) 12V power supply, for the card slot ON OFF OFF
Table 1: Description of Power Supply Systems
Power is supplied to the AC adapter and battery pack in that order when the RTC power is off or is in
suspend mode. When neither power supply can be accessed, power is supplied from the clock battery
(RTC battery).

4.2. Power-On Self Test (Boot Check)
4.2.1. Outline of POST
The set has a boot check function called POST (Power-On Self Test) in it. The condition of the main body is diagnosed by checking
beep sound or error code.
l Start .............Test begins automatically when power switch is set to ON.
l Normal finish .....After memory checking, a beep sound is issued once and the set is placed into automatic stop.
Note: If no error occurs, nothing is displayed. (No display of OK, etc.)
4.2.2. Error Diagnosis by Checking Beep Signal Sound
The beep sound is as follows:

4.3. List of Error Codes
The following is a list of the messages that BIOS can display. Most of them occur during POST. Some of them display informa-tion
about a hardware device, e.g., the amount of memory installed. Others may indicate a problem with a device, such as the way
it has been configured. Following the list are explanations of the messages and remedies for reported problems.
If your system displays one of except the messages marked below with an asterisk (*), write down the message and contact
Panasonic Technical Support. If your system fails after you make changes in the Setup menus, reset the computer, enter Setup and
install Setup defaults or correct the error.
0200 Failure Fixed Disk
Fixed disk in not working or not configured properly. Check to see if fixed disk is attached properly. Run Setup. Find out
if the fixed-disk type is correctly identified.
0210 Stuck key
Stuck key on keyboard.
0211 Keyboard error
Keyboard not working.
0212 Keyboard Controller Failed
Keyboard controller failed test. May require replacing keyboard controller.
0213 Keyboard locked - Unlock key switch
Unlock the system to proceed.
0230 System RAM Failed at offset :
System RAM failed at offset
0231 Shadow RAM Failed at offset :
Shadow RAM failed at offset
0232 Extended RAM Failed at offset :
Extended memory not working or not configured properly at offset
0250 System battery is dead - Replace and run SETUP
The CMOS clock battery indicator shows the battery is dead. Replace the battery and run Setup to reconfigure the system.
*0251 System CMOS checksum bad - Default configuration used
System CMOS has been corrupted or modified incorrectly, perhaps by an application program that changes data
stored in CMOS. The BIOS installed Default SETUP Values. If you do not want these values, enter Setup and enter your
own values. If the error persists, check the system battery or contact Panasonic Technical Support.
0260 System timer error
The timer test failed. Requires repair of system board.
0270 Real time clock error
Real-time clock fails BIOS test. May require board repair.
*0280 Previous boot incomplete - Default configuration used
Previous POST did not complete successfully. POST loads default values and offers to run Setup. If the failure was caused
by incorrect values and they are not corrected, the next boot will likely fail. On systems with control of wait states, improper
Setup settings can also terminate POST and cause this error on the next boot. Run Setup and verify that the wait-state
configuration is correct. This error is cleared the next time the system is booted.
0281 Memory Size found by POST differed from EISA CMOS
Memory size found by POST differed from EISA CMOS.
02B0 Diskette drive A error
02B1 Diskette drive B error
Drive A: or B: is present but fails the BIOS POST diskette tests. Check to see that the drive is defined with the proper
diskette type in Setup and that the diskette drive is attached correctly.
02B2 Incorrect Drive A type - run SETUP
Type of floppy drive A: not correctly identified in Setup.
02B3 Incorrect Drive B type - run SETUP
Type of floppy drive B: not correctly identified in Setup.

I/O device IRQ conflict error.
Operating System not found
Operating system cannot be located on either drive A: or drive C:. Enter Setup and see if fixed disk and drive A: are properly
identified.
Parity Check 1
Parity error found in the system bus. BIOS attempts to locate the address and display it on the screen. If it cannot locate the
address, it displays ????. Parity is a method for checking errors in binary data. A parity error indicates that some data has
been corrupted.
Parity Check 2
Parity error found in the I/O bus. BIOS attempts to locate the address and display it on the screen. If it cannot locate the
address, it displays ????.
