how to disassemble RM-887

[Guest]

Hello service gurus,

I would like to ask a simple question. Hopefully this will be a very easy one for you, but I cannot find the way to do it myself.
I have TV Sony with remote control RM-887. The question is how to disassemble it. I removed the cover for batteries and unscrewed the bolt. But it does not open. Even if I push in all directions.

Please help if you have some experience. I don't want to break it.
