• IrDA test...
Performs the IrDA communication test. Another personal computer to communicate with is necessary for this test. The
models released from the year 2000 have already been confirmed that they do not cause any problems regarding the IrDA
communication. Even models released before 2000 will cause no problem if the same type of IrDA communication IC
chip (the IC chip used in the SIE block connected to the Extend I/O bus) is used in both personal computers that are
connected. In other combinations, the IrDA communication test is not confirmed. (Use of the models released from the
year 2000 is recommended.)
1. Place the two computers so that their IrDA transmitter and receiver ports face each other.
2. Start up the personal computer at the other end of the IrDA communication test connection using the tool floppy disk
that must be created beforehand by copying programs from the service diagnostics CD disc. (Prepare a floppy disk
that is formatted to contain the DOS system. Create a tool floppy disk by copying the entire TOOL folder of the CD
disc to a floppy disk.)
3. Select the IrDA communication test from the menu at the connected computer to enter the reception state.
4. After the connected personal computer has entered the reception state, select the IrDA communication test at the
personal computer to be tested. The IrDA communication test then starts.
• Jog dial test...
The computer cannot perform this test.
• Short aging test.../Long aging test...
Performs the aging test. The short aging test ends when all test items have been performed once. The long aging test checks
the machine for about 10 hours by repeating the test items.
• Aging test including the HDD...
NOTE: Note that this test destroys the entire contents of the user's hard disk drive.
Perform this test only when destructive testing of HDD is desired.
The aging test is performed first, then read and write tests of the hard disk are implemented following the aging test.
There are two tests; SHORT and LONG. However, the contents of the SHORT aging test are the same as those of the
LONG aging test. The test starts immediately when the menu item is selected.
• Exit from Diagnostics MENU...
Quits the service diagnostics program and the DOS prompt appears. If you exit the service diagnostics program by
mistake, start up the program again.
