Treatment timer:
Timer Accuracy: ±0.5 minutes for times less than 5 minutes
±10% for times from 5 to 10 minutes
±1.0 minute for times greater that 10 minutes
±5%, CE specification
Maximum Treatment Time: 60 minutes–electrical stimulation
30 minutes–ultrasound or combination therapy
Treatment Timer: Treatment time counts down to zero when a time is set, or up
to 60 or 30 minutes when no time is set. The digital timer
indicates time in minutes and seconds. The timer also
indicates the remaining or elapsed treatment time during the
“Hold” period.

Output description: The output waveform is continuous or pulsed as programmed
by the membrane panel control. In the pulse mode the 1, 3.2
or 3.3 MHz square wave pulses
are modulated. The power level is adjusted by varying the
pulse amplitude. The pulse waveforms are shown
