don't touch the knobs

Dietmar said something strange. "I wish there was an easy way to stop people from playing with these [balance knobs on the Paramount]."

1. Members are not playing with them.
2. Few of the supervisors are playing with them.
3. It is likely they loosen or tighten over long periods of time.
4. It is likely they loosen or tighten with extreme temperature changes.
5. Improper setting affects pointing. 
6. There's no way to stop people from touching them.
7. Therefore, they need to be adjusted on a regular basis.

I suggested he teach the supervisors how to set them. Instead of saying, "Don't ever touch them."
