That exemplary design element goes back to the JR 347. It was a problem then, requiring occasional tightening of the clip tension, and remains a problem today. Since JR has never oficially seen it as a problem...........

I hooked up my charger today and noticed it was behaving strangely and disconnected. I turned on my transmitter and it was completely dead. Checked the battery pack which was OK so I decided to take a look inside. I was surprised to find a fuse buried under the circuit board behind the antenna. Its visible if you remove the transmitter module on the back of the transmitter. I was able to test the fuse through the opening afforded when the transmitter module is removed and it was indeed blown. I found it difficult to remove through the opening so I went at it the hard way which involves removing the antenna, back panel circuit board and charging connector. The fuse is a 5x20mm 3A fast blow and is available at Radio Shack. I replaced the fuse and powered up without any problem. Its still a mystery why it blew. It seems related to the act of plugging in the charging connector which I have done hundreds of times before but I don't have a good theory of conditions that would create a high current condition. For grins I decided to check that fine JR8103 users manual for reference to the fuse, looking in the index, oh yea - there is no index, lets see, Table of Contents, hmmm component specifications, no, general information, no, general notes, no, ...could'nt find any mention of it. It may be in there so I won't trash their manual too badly this time around. I just wonder how many transmitters have been sent in to be repaired because of a blown fuse, I wonder if Oliver Stone knows anything...
