[CQ-Contest] anyone have a DU3500AL antenna tuner?

[AB2E Darrell]

Hello all,
By any chance does anyone have an HA8DU DU3500AL high power auto antenna tuner?
I need some help with tuning it.
The manual is lacking several key component labels and functions, but mainly the process used to get it going.

DXE deferred to HA8DU, who sent me another copy of the manual but that is no help because many things are not addressed in the manual.

Thanks and 73,
Darrell AB2E​
