This instructable is going to show you a quick process which will allow you to convert a cheap portable cellphone jammer from Chinese frequency's (I think) over to American or other regions frequency's.
In this step we will simply want to remove the top and bottom plates from the outer casing.
You will need:
- A small phillips head screwdriver
- a pair of pliers - optional
The first thing you're going to want to remove is the three antennas because the top plate will not come off properly with them attached. Next, there are four small screws which hold the top and bottom plates to the aluminum casing, remove these screws and then remove the on/off button from the side using the pliers or your fingers, pretty simple.
Make sure you don't lose the screws, put them aside with their respective cover piece.
