Hi, Kent!
Kindly take one more look at that warning. It is referring to the
internal RF Power Level control (R4 trimmer pot).
The RF Gain pot topside is expected to see much more use and was
selected because it will last a long time.
Merry Christmas!

However, by comparison, during assembly of a KX1 I did note the
warning in the manual about not turning the RF gain control too
frequently because that pot "has a life expectancy of 200 rotations."
Hmmmmmm. I know I've rotated the RF gain (and also the AF gain) on
the R4-B a lot more than 200 revolutions over 36 years and have yet to
need even a squirt of De-Oxit on either one of those pots.
