To ensure safe operation the three-pin plug must be inserted only into a standard three-pin power point
which is effectively earthed through the normal household wiring.
Extension cords used with the equipment must be three-core and be correctly wired to provide connection to earth. Wrongly wired extension cords are a major cause of fatalities.
The fact that the equipment operates satisfactorily does not imply that the power point is earthed and
that the installation is completely safe.
For your safety, if you have any doubt about the effective earthing of the power point, consult a qualified electrician.
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.
Warning: THIS APPLIANCE MUST BE EARTHED.
Important
The wires in this mains lead are coloured in accordance with the following code:
Green-and-yellow:Earth
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:
The wire which is coloured GREEN-and-YELLOW must be connected to the terminal in the plug
which is marked by the letter E or by the safety earth symbol
YELLOW.
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.
coloured GREEN or GREEN-and-
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 screwdriver 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-conduciveparts 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.

2 Power-On Self Test (Boot Check)
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.
Start .............Test begins automatically when power switch is set to ON.
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.)
Error Diagnosis by Checking Beep Signal Sound
The beep sound is as follows:
(1 (long sound) -2-3-4)
(Length of bar shows length of sound.)
= long sound (about 0.4 sec.),

3. ListofErrorCodes<Only when the port replicator is connected>
The following is a list of the messages that BIOS can display. Most of them occur during POST.
Some of them display information 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: nnnn
System RAM failed at offset nnnn of in the 64k block at which the error was detected.
0231 Shadow RAM Failed at offset: nnnn
Shadow RAM failed at offset nnnn of the 64k block at which the error was detected.
0232 Extended RAM Failed at offset: nnnn
Extended memory not working or not configured properly at offset nnnn.
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.

02F7: Fail - Safe Timer NMI Failed
ServerBIOS2 test error: Fail-Safe Timer takes too long.
device address Conflict
Address conflict for specified device.
Allocation Error for: device
Run ISA or EISA Configuration Utility to resolve resource conflict for the specified device.
Failing Bits: nnnn
The hex number nnnn is a map of the bits at the RAM address which failed the memory test.
Each 1 (one) in the map indicates a failed bit. See error 230,231 or 232 for offset address of
the failure in System, Extended or Shadow memory.
Invalid System Configuration Data
Problem with NVRAM (CMOS) data.
I/O device IRQ conflict
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 nnnn
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 nnnn
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 ????.
Press <F1> to resume, <F2> to Setup
