TECH NOTE By: Jimmie Bates

Summary

This document is intended to walk an end-user through the procedure to replace the
SPROM programming IC in your Quantum Composers Pulse Generator. Only someone
familiar with handling of electronic equipment should perform the following procedure.

Please adhere to all safety precautions outlined in this document!

Introduction

1) Disconnect the power cord. The power
supply inside the Pulse Generator has exposed
surfaces that have live grid voltage when the unit is
plugged in. Electrical shock could occur if the unit
is not disconnected from the power source. You

must disconnect the power cord.

2) Disconnect any other instruments
connected to the Pulse Generator. This ensures the
protection of the extraneous instruments, the end­user, and the Pulse Generator from damage caused
by inadvertent short circuits, etc.

3) Remove the front and rear bezels by pulling
away from the side of the Pulse Generator and

twisting the side of the bezel out.

4) Remove the top screws from the front & rear
panels.

5) Remove the top cover. Do this by inserting a
coin, or other relatively dull tool, into the top gap on the
side of the unit and twist to “pop loose” one side of the
cover.

6) Without lifting the side that has been
popped loose, repeat the procedure on the other
side of the cover. Lift the cover straight up to
remove.

7) The IC to be replaced has the location
reference U6. This IC is located in the rear, left
hand side of the main board.

8) Carefully remove the old IC. This is
generally easier when using an IC pulling tool as
depicted.

9) Replace the old IC with the new SPROM
IC from Quantum Composers. Be certain to orient
the chip correctly! There is a U-shaped indention
on one side of the chip that needs to be aligned
with the same U-shaped indention of the image of
the chip on the board.

10) Reassemble the unit by following steps 1
through 6 in reverse order.

11) Plug in the power cord and turn on the
Pulse Generator. Ensure that the unit boots and
functions properly. If this is not the case, contact
technical support for further assistance.

12) Reconnect other instruments.
