1.When everything is A-OK, your screen reads:

INSERT DISKETTE

2.When there is an abnormality somewhere, and it’s time to call your Epson service center, you11 hear a buzzer and see the message:

DIAGNOSTIC CODE 0001

with a 3-character suffix or you’ll hear the buzzer and see the message:

DIAGNOSTIC CODE 0002

3.When something is wrong with the central processing unit (CPU), you might or might not see the DIAGNOSTIC CODE 0001 message, and you might or might not hear the buzzer. Check the small red light labelled POWER at the right front of the main unit. If it is not lit, the CPU is probably defective.

WARNING: Neither the monitor nor the keyboard should ever be opened except by a trained QX-10 service specialist. This is also true for the main unit, except for the cover on the left side that protects the option card slots. You’ll need to open it to install or remove option cards.

WARNING: Never open the QX-l0 while it is plugged into a wall outlet!

If you do have problems you can’t solve yourself, call your Epson dealer or authorized Epson service center.
