 - Bend down (or up, depending on your perspective) the half-circle thingie.  (You may choose to flatten the nub, or bend down the metal half-circle. Or you could even go so far as to separate the white plastic from the metal bottom and remove the detent disc completely with no fuss. It snaps right back together (pic coming). Either way will accomplish the job.  The point is to move the metal nub that falls into the valleys on the spinning disk.)\\ - Bend down (or up, depending on your perspective) the half-circle thingie.  (You may choose to flatten the nub, or bend down the metal half-circle.

 The encoders will behave with an 'acceleration' feature, similar to that of the PC mouse - when you turn the encoder faster, the values will increase at a faster rate. This mean that you can turn the knob slowly for more precise adjustment, or turn quickly for coarse adjustment of parameters. The encoders will behave with an 'acceleration' feature, similar to that of the PC mouse - when you turn the encoder faster, the values will increase at a faster rate.
