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 OKIf 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 appropriate 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.
