Glad to hear that things seem to be behaving better.

The Adobe reader is a free download (and isn't that large), so in the long
term it would be a good thing to get.

The whole manual is 50+ pages - but the data is good to have. Specifically,
the info in the "Adjustments and Checkout" section are certainly good to
have.

With regard to the DC OK setting, here's the two para.'s that deal with
that:

===================

DC OK THRESHOLD:
---------------

The factory setting for the DC OK threshold requires the use of a rather
elaborate test circuit; however, it is sufficient in the field to simply
back off on R17 to minimum (full CCW), then turn it clockwise until LED CR10
lights. The nominal DC level out at DC OK (P3 pin 1, brown wire) is +3V.

Late serial numbers use a different secondary board with a moidified DC OK
circuit. ON these no adjustment is necessary or provided. The nomimal DC
level out at DC OK (P34 pin 1, brown wire) is +5V.
