tx-29gf10x remote how do you open this remote

[iversonis]

I want to clean up the inside of this 4year old tv remote.

TV model: Panasonic tx-29gf10x

Does anyone have instruction on how to open this?

Its a very weird stylish looking remote which opens up like some mobil
phones..

Please help, I spent one hour trying to figure this out!

The joint part of the remote in inseparable!

Help!
