After finish from soldering, now it is time to grave a slot at the back cover of remote control.
You will need a small drill. I'm using my Dremel Cordless Rotary Tool.
* First, try to locate and mark where the header pins go trough. You have to be patient.
* When necessarily, remove any extra parts from the heard way.
* Try not to make oversize slot hole, otherwise, you may face some problems when placing on base.
* Have a look at the slot from the back to make sure everything is fine.
* Finally, place back both covers together.
* Apply some glue to hold the header pins from move or broke.
