Just to add a bit to that, use the NiCd Linear charge mode & set the voltage threshold to 5mV(to start, try that setting & see how the cells feel after they peak, if they seem a bit warm, then try a step smaller threshold). That's how I charge my micro packs(I also have an original Millenium & a Millenium Pro, the non-Pro is what I typically use for the micro packs & for my transmitter batteries, works quite well)....
