It's orange on mine. I ran it for several years in class A, less than
full power, into a 6m transverter. I was very active and never had a
problem with it.

On the FT-1000MP MKV, the button is not orange and power is internally
limited to 75 Watts.
However, as Charly said, you must NEVER use less than 75 Watts, as the
MKV cooling system is p1ss poor and the finals WILL burn up. I found
out the hard way and thankfully, I was able to source some "real"
replacements and the radio was able to be repaired. I think they are
BLF147 or something like that.
Anyway, take care, cos they are very hard to find. You can get the
re-badged Chinese reconditioned version easily but genuine ones are
very hard to find.

The "Orange button" is the Class A switch, but it should not be run
at more than 75 Watts. It just switches the bias.

What is this 'orange' button of which you speak?
