Q: If I found a commercially available product containing a brushless motor attached to a fan, must it be labeled as a "cooling fan" to be legal? (section: 4/ paragraph: i/ sub-paragraph: / line:1 )
A: No. As long as it is a fan typically used for cooling electronics or computers it does not need to be labeled as such.
Q: Can commercially available rechargeable battery packs that are labeled <= 9.0 V be used as a power source. (section: 4/ paragraph: 4/ sub-paragraph: / line: 1)
