I found this info on the web while trying to assemble a Golden tutorial for myself. At this point I don't know who the original author was, but it's useful information, so I thought I'd share for those of you who might be interested:
New Tones, Conductivity Range
Ferrous/Iron/Foil Low
Nickel Medium High
Pull Tab/Zinc Penny Medium Low
Silver High
Old Tones, Conductivity Range
Ferrous/Iron/Foil Low
Nickel Medium Low
Pull Tab/Zinc Penny Medium High
Silver High
The notch-width control must be adjusted while air testing a nickel with the discriminate control turned completely down to "min". With the notch switch in either the wide or narrow position, adjust the notch-width to obtain a good target sound on nickel. This will give you four target tones. If the notch-width is NOT set correctly, you will only hear three tones. This is the correct way to setup a Golden µMax, regardless of whether it has the new or the older Tones.
