Vincent,
Many of the functions which are not working are reliant on the multiplexor
bus (the two 4051s). Given this you should definitely attempt the, first ,
the reset procedure (the one with the 56K dummy load) and then, second, the
D/A convertor before you do anything else. Make sure the controller are set
as per the diagram at the start of the calibration section of the manual.
You may find some marked improvements when this is completed!
Cheers,
Andy
