With the CG tuner you would have to take the amp off line manually, then
key your rig so a tune cycle would take place. I'm sure the tuner
instructions state to do this at low power 10-20 watts. Most modern
rigs reduce the power when they see a high swr, so you normally wouldn't
have to reduce the power manually.
Once the tuner is tuned you could hit the amp operate/standby switch and
start running with high power.
I would probably forget to turn the amp off in the heat of the moment, I
would rather the tuner interrupt the ptt line so tuning is totally
automatic.
