My Furuno radar, model 1941 MKII, wont change range. It has stopped responding to the decrease range key. These are the “rubber" keys common on stuff. Any ideas or suggestions before I try to open the box? Any Idea what to expect with the keys??
If it's what I think it is, I don't think WD-40 will do any good as it will not get to the switch. You may have to remove the facr plate to get to the little button switches under the rubber buttons.
