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,

hear a buzzer and see

the message:

DIAGNOSTIC CODE 0001

with a

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, ex-

cept 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.
