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.

an area of 1, 5 or 10 cm², measured 5 mm from the ceramic
disc surface when the radiation is emitted into the equivalent

The beam of the applicator is circular in all planes parallel to
the applicator face. A few inches from the face, it is a single
smooth bell-shaped curve. Nearer the face the pattern varies
more due to phase cancellations. Sample curves measured in
the far field from the surface are shown in Figures 3.3, 3.4,
3.5 and 3.6.
