For this check, the program writes specific data into memory and then
reads it back. The data is written and read in blocks of 64KB. A parity check
is also made on each block. A count of memory is displayed after each block
that is tested without an error. The final message is usually:
640
KB OK
If an error is reported, write down the error code and message, or print
them out, and contact your Epson dealer. Attempting to correct memory
errors yourself may violate your warranty agreement.
Keyboard Check
Use this option to check the operation of the keyboard. The program
first checks the keyboard controller; during this check, you see the green
indicator lights on the keyboard flash. If no errors are detected, you can then
choose the correct keyboard layout.
Before checking the operation of the keys, you must select the appro-
priate keyboard layout so that the test display matches the keys on your
keyboard. You see this menu:

Enter selection number:
Type the number of your keyboard layout, then press
Enter. You can
exit
the keyboard test by pressing 8 and
Enter.
After you select a keyboard layout, the program displays the layout on
the screen. Press each key on the keyboard to make sure the corresponding
character is displayed on the screen. If the character displayed on the screen
does not match the key you pressed, there is a problem with your keyboard.
Test each key.
