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??
 
Try wiggling on the + key. It may be stuck.
 
yup tried that. hit it with wd40 will try again tomorrow
 
When you say "rubber" you don't mean the membrane type do you Bruce?
 
not sure whats inside the keys that protrude from the faceplate are rubbery not hard plastic.
 
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.
 
A good 10 lb. brass hammer will fix anything, and will not spark if you
own a gas powered boat.
