Adding a JP1 connector to the RCU810 remote is a little bit more complicated that adding one to a remote like the Cinema 7, so I have outlined the steps involved here.
First you have to take the remote apart. Remove the screw in the battery compartment, then pry the two sides apart. Read Tommy Tyler's Instructions if you have difficulty doing this. Personally, I slide an old credit card into the crack at the lower end of one side, and proceed to seperate the two parts.
