Thank you for pointing this out, and we apologize for the confusion. The correct RF frequency for this FY13.0007US model is 3MHz. The 3-pole, 4-pole, and 6-pole RF heads all operate at 3MHz. The 80KHz specification refers separately to the ultrasonic cavitation head. The 1MHz information shown elsewhere on the page is outdated/incorrect, and we will have it corrected.
