You have to pry the bottom copper cap off very carefully. After that, the white handle should slide off. However, I have noticed that on some remotes there is no glue holding the white handle to the rest of the remote, and on others, there is a generous amount of glue holding the bloody thing on there, so its kind of a toss up. As for screws, the only screws I purchased was the 6-32 set screw for the emitter.
