[time-nuts] Austron 1210D-03 Manual?

[John Ackermann N8UR]

I managed to pick up the Austron 1210D-03 portable clock that was 
offered up here a little while ago, and the thing is ticking away nicely 
on my bench.  However, I don't have any docs for it, and in particular 
the PPS sync and slew controls on the front aren't entirely 
self-explanatory.

Does anyone have a manual for this thing?  Failing that, basic operating 
instructions would do.

Thanks!

John
