Epson Y16499100301 - Manual (Page 110)

Type the number of your keyboard layout and press Enter.
You can exit the keyboard test by pressing 0 and
Enter.
After you select a keyboard layout, the program displays
the layout on the screen. Press each key on the keyboard to be
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.
The status of the Num Lock, Caps Lock, and Scroll Lock
indicators is shown on the upper right side of the keyboard
layout.
These messages appear on the screen:
KEYBOARD CHECK
Press Y followed by ENTER to exit.
Press N followed by ENTER if screen and
keyboard do
not match.
If all the keys function correctly and match the characters
displayed, press Y and then
Enter.
If all the keys function, but the characters displayed do not
match the keys, press Y and then Enter. Then re-select the
keyboard test from the DEVICE LIST and check that you
selected the correct keyboard layout. You can find diagrams of
all the international keyboard layouts in the MS-DOS manual.
If any key is incorrect, press N and Enter. Make a copy of
the error code and message, or print them out, and contact
your Epson dealer.
Video Adapter and Display Check
Use this option to check the operation of the LCD or
monitor connected to your computer. This test includes several
checks that allow you to identify particular problems related to
the color display. If you are using the LCD screen, you cannot
see any color; so the colors are displayed in monochrome tones.
