the total amount of usable memory available will be less
depending on the actual system configuration.
*3 A segment of the main memory is allotted automatically
depending on the computer’s operating status. The size of
the Video Memory cannot be set by the user.
*4 1GB = 1,000,000,000 bytes. Your operating system or some
application software will report as fewer GB.

4.2. Troubleshooting
Please take note of the following two points with regard to troubleshooting:
1. Know-how of diagnosis upon occurrence of heavy troubles, e.g. ‘Set cannot be turned ON’, ‘Set fails to start’, ‘No display on
screen’, etc.
2. Explanation of each trouble, mainly symptom of trouble in operation.

5 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.
zStart .............Test begins automatically when power switch is set to ON.
zNormal 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:
= long sound (about 0.4 sec.), = short sound (about 0.2 sec.), Length between sounds is about 0.1 sec.

6 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 offsetnnnn.
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 termi-
nate 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.

Standard at test time
All devices other than RAM and HDD ---------- about 1 minute
RAM standard test ----------------------------------- 1 - 2 minutes
HDD standard test ----------------------------------- 2 - 3 minutes
HDD enhancing test (60GB) ---------------------- about 40 minutes
Ex.The standard when the standard <all device> is tested becomes 1+2+3=6 minutes.
■There is greatly a difference from RAM test when the memory is increased according to the performance
of the memory occasionally.
■Moreover, when the main body of PC under the test is a high temperature, it occasionally takes time.
■There is greatly a difference from HDD according to the performance of the drive occasionally.
2-1. Selection of tested device
-To test only a specific device, "Test" and "Do not test" of each device can be selected.
