Testing

Step 30 - Initial Integrity Test
The big moment has arrived where we see the instrument working with its new HAWK upgrade in place. But before we do
anything more, we need to carry out an initial integrity test to make sure that the new board was constructed and installed
correctly.
Make sure your synthesizer is switched off.
●
Plug in the power pack.
●
If all goes well the synthesizer should power up and will initially flash "88 88 88" followed by "HA-800" for several seconds
before then moving through some error messages.
If you don't see anything on the display at all then you need to go back and check all of your work again.
If you DO see flashing "88 88 88" followed by "HA-800" then most likely your HAWK installation is working.
Turn off your synthesizer.
●
Close up the synthesizer and re-install all of the case screws.
●
Clean up your work area and put away your tools.
●
NOTE: It is normal to see error messages "Error 4", "Error 5" and "Error 6" when you install the HAWK-800. Those three
messages indicate that the HAWK does not have working flash software loaded into the software flash ROM. If you see any
other error messages (Error 0, Error 1 or Error 3) then you have a problem with your HAWK installation. Check your work
thoroughly, especially the soldering on the HAWK board itself. Also check the soldering of the EPROM socket and IC29
socket. Also check that the ribbon cables are installed correctly and no pins are bent over or broken. See the owners
manual (pages 35-37) for the list of power on self tests and what they mean. Also see the addendum on troubleshooting
the installation (see below for the addendum on troubleshooting).
