Environmental Disposal: The device contains lead in the form of solder used to
produce electrical contact between components. To avoid
adverse environmental impact, utilize a disposal facility that
performs complete incineration of the device at a temperature
in excess of 1000°C.
The shipping materials are fabricated of cardboard and may
be disposed of with other paper products.
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
1
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.
