Congratulations!
Congratulations on your purchase of the HAWK-800 retrofit kit. This kit provides your Poly 800, Poly-800 MK2 or EX-800
with many new and exciting sound creation and control capabilities. See
http://www.hawk800.com
for the latest list of
completed and supported features as well as patches, templates and owners documentation.
WARNING and DISCLAIMER
You take full responsibility for any outcome, good, bad or ugly, when constructing, installing and using this retrofit kit. Do
NOT attempt to construct, install or use this retrofit kit unless you understand and are willing to accept responsibility for
any outcome that may result from your own attempts to construct, install and use this kit.
NOTE: This kit requires the removal of two components from the main Poly-800 (and MK2) or EX-800 printed circuit boards
(PCB's). This requires advanced electronics technician skills. If you do not have the skills required to remove a 16 pin IC and
a 28 pin DIP socket then you should have someone else do the job for you. Your local music store should be able to help
you to find a qualified technician in your area. The successful installation of this kit into the Poly-800 MK2 requires even
more skilled work. Beware and consider yourself forewarned!
Special final WARNING!
You should NEVER attempt to install the AtomaHawk kit without first having installed and then successfully tested and
operated your Poly-800 with ONLY the HAWK-800 kit installed. Do NOT attempt to install the HAWK-800 and the
AtomaHawk in one installation session. Troubleshooting and repair of your Poly-800 becomes extremely difficult if not
impossible if you attempt to install both kits in one installation session. Do NOT attempt it! We recommend that you install
the HAWK-800 kit; wait until you have had a full 8 hours of continuous successful operation of your Poly-800 with the
HAWK-800 kit installed; then follow up later with the installation of the AtomaHawk kit.
Safety First
NOTE: Exercise appropriate safety precautions at all times during construction and installation of this kit.
Before you Begin
When you ordered your kit you would have specified either a Poly-800 MK1 kit (HAWK-800P) or an EX-800 kit (HAWK-
800EX) or a Poly-800 MK2 kit (HAWK-800MK2). It is critically important to make sure that you obtained the correct kit, that
you received all of the components in the kit and that none of the components show any sign of physical damage. Use the
bill of materials that came with the kit to ensure that the correct kit and parts have been supplied and use the table below
to make sure that the ribbon header cables that were shipped are correct for the kit that you ordered.
