Epson Apex 20020 - Manual (Page 139)

6. If you are running an application program, check to make
sure the program is set up for the type of monitor you have.
Some programs need to be set up specifically for the type of
monitor you are using.
Note
If your application program requires a monitor that
supports graphics but you have a monochrome monitor,
the results will be unpredictable.
7. If you are still having difficulty with your monitor, try
running either the Monochrome Display Adapter and CRT
Check or the Color Graphics Display Adapter and CRT
Check, both of which are described in Appendix C of this
manual. If the diagnostics program indicates an error,
contact the place where you bought the monitor. If you are
using an Apex monitor, call your Epson Customer Care
Center for assistance.
Diskette Problems
If you have trouble accessing data on a diskette, try the
following steps:
1. Remove the diskette from the diskette drive and reinsert it.
Repeat the operation that gave you trouble. This usually
solves the problem if the diskette was not seated properly in
the drive.
2. If reinserting the diskette does not solve the problem, and
you have access to another diskette drive of the same type,
place the diskette in the other diskette drive and repeat the
operation. If you can successfully perform the operation in
the new drive, the trouble may be in your diskette drive.
See the section below on “Diskette Drive Problems.”
