Infinite Switch (Dual)

I am having a great deal of difficulty trying to figure out how to convert my wiring from my old switch (7403P812-60) to the new replacement switch (12002125). I have received an instruction sheet and can’t seem to follow it.

I have the following connections on my old switch:
-White wire going to (H1)3
-Dual red wire going to (L2)H
-Singe red wire going to (L2)H
-Yellow wire going to 4(H2)
-Orange wire going to 0.5A
-Dual black wire going to 2(L1)

Please advise
