Step 1: Dissasembly of the Jammer
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.
Step 2: Removing the inner circuit board and locating the adjustable caps.
Once the top and bottom plates are removed the inner board will slide out with some slight pressure. Once the boards out you just want to find the 6 small variable capacitors towards the middle of the board.
