|CES Model 975 - Computer
just received my new 975 trainer, unpacked it, turned it on, and
nothing happened. What is wrong?
All of our trainers
are shipped fully assembled and tested, and have undergone 72 hours of
bench burn in before shipping. The 975 trainer is final inspected by an
A+ Certified technician before the trainer is packed and shipped. If you
receive a 975 trainer that you feel is not working,
or is exhibiting a "dead on arrival" symptom, the trainer may have
suffered concealed damage in shipping. You can try the following steps to see
if it resolves the situation, if not, contact support.
- Recheck that all connectors are properly inserted into their correct location.
- Check to see that the trainer is plugged into a 120 V outlet, and that
the outlet is receiving power.
- Check the position of the intensity controls on the monitor, be sure that
you set them to the mid
scale position, if the monitor supplied uses analog controls. If the monitor
uses digital controls,
press the control to see if video is present on the monitor.
- Check the position of the fault insertion switches. Both the monitor and
the computer system
unit have fault insertion switches that must be set to the "0" or off position
for the trainer to function properly.
- TURN OFF THE TRAINER POWER, remove the 6 screws
from the glass cover, and firmly, but carefully,
press all of the expansion cards down, into their sockets.
Turn on the trainer and verify proper operation.
- TURN OFF THE TRAINER POWER, Remove the sound
card, and POST diagnostic card, turn on the trainer
and verify operation.
- TURN OFF THE TRAINER POWER, replace all cards
you removed in step 6, into the trainer, turn on the power
to the trainer, and make note of any numbers displayed on the POST card and
contact technical support.
has been operating perfectly, but now I have no sound when the student
runs the multimedia presentation. What is wrong?
This is most
likely not a hardware issue, but a problem with the sound card drivers.
Either the sound card drivers have been removed by the student or by
a problem with Windows. Simply locate the sound card drivers that are
with the instructors package, and reinstall the sound card drivers.
If this solves the problem, you will notice that Windows will place a
of a speaker in the system tray next to the time of day clock.

What program do you recommend? What effect will this have on my trainer? We have evaluated several different, commercially available
protection programs available for Windows 9X. All these programs work
to prevent access to various functions available to the user. The purpose
of this trainer is a computer repair trainer, and we do not recommend
or sanction the installation of any software that restricts access to
the computer. Since the laboratory experiments manipulate the hardware
directly in some cases and other experiments require DOS access, these
lock out programs will directly interfere with the operation of the repair
trainer. If school policy or your personal preference dictates that you
install a lock down program, please note that you are doing so at your
own risk, and consequences. CES Industries, Inc. cannot be held responsible
for experiments that do not function as described in the instructors manual,
or student manual if the trainer has any software that interferes with
the normal operation of the Windows operating system. This includes anti-virus
programs as well. The trainer is supplied with an emergency recovery disk,
that in the event the student damages the computer, you can recover the
system to factory specification by simply using the emergency recovery
presentation disk has disappeared, what do I do now?

I use the disk, it starts to run, then the computer freezes. I can use
other programs without this happening.
This problem is usually associated
with the CD-ROM drive itself. You can overcome this problem by changing
the read-ahead setting in Windows. Select the Start... Settings.... Control
Panel... System settings and then select the performance tab. Under File
system, select CD-ROM and from the drop down box, which is normally set
to "Quad Speed or Higher" change this setting to No Read Ahead.
You will have to reboot the computer after changing this setting. If this
does not solve the problem, return the disk for replacement.

The fault switch is protected from accidental
activation by a key switch that must be enabled by the instructor.

We do not
recommend that you use this computer repair trainer as a working classroom
computer. This trainer is designed to teach computer technology, and not
