Thanks Mark,

I did do an exhaustive google search. I found that document but unfortunately it wont help. B4A is the newer model that had everything built into the aimer housing. A call to the company turned up empty. The manufacturer sold to another company that doesn't have older documentation.

I have the older B4 model that has separate light meter and site.

This is the correct booklet for this model:
