[Premium-Rx] Manual/s needed for WJ 8618B/-1 with options

[Royce, Alan (Space Technology)]

I am looking for a manual/s for the WJ 8618B and WJ 8618B-1 and the options manuals.
I need the operation manual for these two receivers to cover how to get into the extended receiving range.
 I need the option manuals to cover the three or four pcb's ahead of the antenna board. 
I think that these boards are for the extended receiving range. These receivers are like the S1, but are not an S1.
Copies would be fine. I can do the coping on this end.
Thanks Al
