I have just tried this on my FT1kMP but couldn't see any change so may 
be the MP has fixed gain.

On all bands the ALC level is past the end of the red line but around 
75% along the whole scale (the instructions are a little vague about the 
actual position.) Level with the 100w marker on the PO scale,

The default level was at maximum, 15, and varying it did not make any 
difference to the indicated ALC level.
