for level 2 would i need to have small switch and connector at the bottom of base, and dental file even though it was missing just to adhear to crl.
one reference you showed there was no switch or button, and on had both, and one had the cable plugged into the bottom.
or can you do either one or the other.
i think it mentions the 2 rivots it want' the one with switch and connector. as the pic without didn't have rivots
