Thus, I've had this oven with micorwave above it for 8 years now
This morning, perhaps because I am getting shorter, as I was cleaning the range and the outside of the microwave (using Simple Green), I've noticed two labels at the bottom of the microwave, both start with Caution.
The only way to be able to read it is to lie flat on the top of the range and read it. I can use a mirror but then will have to be able to read it upside down and backwards.
I managed to read one of them, in larger letters, telling to clean the filter regularly in mild detergent and warm water (I put it in the dishwasher). Also to unplug it when replacing a part - not my concern. I have service people do this.
The second note, all I could read Caution, this device is for use only...
I tried two mirrors but one really has to know how to aim them.
Oh well, I suppose after eight years these whatever they caution me is irrelevant..
(It is Whirlpool)
= new reply since forum marked as read
..then share with us what it said...cuz now we are curious 
The full message is "Caution, this device is for use only in spying missions!"
Forgot about Kellyann and the microwaves.
(And to think that she is on TIME magazine list of "First Women"
