Got a pair of Sordin 73502. I haven't changed the battery since I got them about 2 years ago and they've sat unused for about 7 months. I unscrew the bolt that opens the batter compartment. One battery drops out. The other which was underneath it, slides up to the hole but refused to pop out it just jiggles around. If I had a manual, who knows where that it is?
I don't see one on their web site. You can call them in Sweden.
Any ideas?
