My equipment is not producing ultrasounds. After selecting Ultrasound therapy, mode of treatment and adjusting W/cm2 the treatment time is not counting down, the stop sign not changing to pause sign, the Ultrasound transducer is not lighting up the blue/green light but is producing a beep sound after pluging its connector onto the machine. So Ultrasound Therapy and Combined Therapy are not working. Please help.
