So far we have three known, new model identifications by the first six characters of the serial number:
G0
00P8, G0
00S1, G0
00SA
This information is used internally, in our package creation and package coding.
We need to know if anyone has an identification string different than those three above.
Tell us now, or your model may not be supported the first time around with new KOA2 packaging.
Because of internal changes by Amazon/Lab126, there may be "KOA2 specific" package versions, at least for awhile.
