Here is the vital info re: verbose mode and terse mode:   
Speech mode 
Your TW-1 will speak in one of two different modes: Verbose and Terse. In
Verbose mode, the 
TW-1 speaks in full sentences, as in "The forward power is ninety seven
watts". In Terse mode, 
only the numerical value is spoken, as in "ninety seven". The default is
Verbose mode. 
After you become accustomed to your TW-1, you will likely want the shorter
readouts, without 
all the extra chit-chat. To select "Terse" mode, press the REV and SWR
buttons together while 
you apply DC power. Thereafter, on pressing a button when RF is present,
only the numerical 
value will be spoken. 
1238
1240
To return to "Verbose" mode, press the FWD and REV buttons together while
you apply DC

Good evening everyone from a dusty Phoenix,

 

I recently sold one of my TW-1 meters and the buyer, an elderly blind ham
down in Tucson, asked me how to turn verbose mode on and off.  In verbose
mode, the meter says something like "The forward power is," when the
left-most button is depressed.  There is a way to have the meter simply
state the value.  Can anyone remind me which button combination takes care
of that function?

 

Thanks in advance.
