No heating at all during Vanquish but tuning full, still working?

The Vanquish treatment works with selective, focus-field radiofrequency (RF) for deep tissue heating of the abdomen and flanks. So yes you should feel warmth & heat. Just because the tuning is 98-99% doesn't mean the power was turned up. The "power" should be turned up and continue the tuning as close to the 90's as possible.
