Steve:
Well, I'm embarrassed to say I didn't know this, and will do the TW2 band
change to 440 the next time I'm out at the RV.
Am I correct in that there is no band change for the TW1 HF watt meter?
I tried your procedure on that one, and couldn't find any band change
options.

Tom,
You need to set to the proper band on the TW-2. Your choices are: 50, 144,
220, and 440.
To hear the currently selected band spoken do a quick press and release of
the FWD and SWR
buttons at the same time. To change band do a longer press of these
buttons and you will hear a tone followed by the newly selected band.
Repeat as needed to get to the band you want.
The manual says being on the wrong band will give you a reading, but not
accurate.
