I noticed that the DIN connector on the start box can move considerably. I also notice that it is soldered into the PCB (Printed Circuit Board) in the box. Being concerned, I tried to remove the PCB so I could inspect the solder joints. It appears that it is only retained by the cover, so when the cover is off it should slide out. I was not able to slide it out, and did not want to force it. Is there some trick to this, or other retainer I did not find, or should I just use a little more muscle?

It is held into the slot with light glue. Pull it our with small vise grip clamped to the end of the pcb near the rotating shaft.
