Nead instructions to set up keyboard

i have Wireless Computing mod FF-250 keyboards. Lost operating instruction. I have been using it to run two PC's mod FF-250 keyboards. Lost operating instruction. I have been using it to run two PC's and want to add it to a third pc.

The key board will run up to 5 PC's. The operating instructions does not come with it but I got the instructions from Wireless Computing and they are no longer on the web only the instruction that comes with the keyboard. This set up requires a FR-015 receiver for each PC which I have.

I need the set up procedure, or contact information to someone that worked for Wireless Computing that may have the information?
