Opening the Radio
This was not too difficult. I found some information online from someone who needed to change the TX modulations.
Remove the battery and the belt clip. Remove the two screws on the back near the battery release switch (watch out for the spring) and remove the two screws on the back of the radio.
Pull the volume knob off, remove the nuts around the volume potentiometer and the antenna connector.
Pry up the back of the radio a bit, and pull that section back and away from the case (watch out for the speaker wire).
At this point you can desolder the speaker wire, but I left mine on because I am lazy.
Remove the screw down by the flashlight LED – this secures the battery connector.
Remove the battery connector
Remove the LCD display, and the screws holding the PCB together. Carefully remove the PCB by working around the antenna connector.
