The "alpha" CNI series doesn't respond much to turning the pot. I did it in my Lucent Envee (same laser, different name) and the difference was hardly noticeable. I just turned it back to the factory setting and left it alone.
If you search, the instructions are out there, but it's really not worth the time.
The most worthwhile mod I did to mine was solder a bypass wire inside the cap so I didn't have to use the stereo plug to turn it on. The key, shutter and 3 second delay are enough IMO.
