Hi , i`m Jack
Perhaps i can help you with this .
Could you look on the serial number sticker for the MODEL number , this could be near the main power switch at the base and/or where the power cord comes in ?
It varies depending on the models but this will be at the base anyway and on a sticker/decal
Sorry but that doesn`t give me the exact model number required for the manual , the " image pro II elliptical " is the serie ,not the model
Please look again for a sticker around the base with that info
Click this link , that may help ; http://support.nordictrack.com/parts-manuals/#ellipticals
O.k then sorry but I will have to opt out now.
You don`t have to do anything , your question will be reposted for other techs. to see and jump in.
Perhaps someone here will have an idea
Can you check my link please for this manual and tell me if it matches the unit you have
