Mine is a Medtronics.... I did not hear about being too close to the engine , but They DID tell me to stay 3' away from the battery..
Also , no more cell phone in the breast pocket if that's where you put yours...
I had to give my welder to my Brother-in law... A welder is a big no-no
They tell you to stay 24" from a working microwave.. I don't ..??
I was told no more electrical work ( did not do any anyway) if you receive a shock , it would-could short circuit your pacer..
Watch your Ipad case if it has the magnetic clamp... If your not paying attention and surfing the web in bed , a lot of times that clasp is on you chest at your pacer... also a big no-no...
Google the topic , you will find a ton of information...
I have had mine since November 27th 2012.. my new Birthday ! :B
