IF is a symptomatic treatment and as such suppresses the sensation of pain
which would otherwise serve as a protective mechanism.
Precautions/adverse Reactions
Isolated cases of skin irritation may occur at the site of electrode placement
following long-term application.
Stimulation should be stopped and electrodes removed until the cause of the
irritation can be determined.
Effectiveness is highly dependent upon patient selection by a person
qualified in the management of pain patients.
If the device treatment becomes ineffective or unpleasant, stimulation should
be discontinued until reevaluation by a physician/clinician.
Always turn the device off before applying or removing electrodes.

TIPS FOR SKIN CARE
Good skin care is important for comfortable use of your device.
z
Always clean the electrode site with mild soap and water solution, rinse well,
and blot dry thoroughly prior to any electrode application.
z
Any excess hair should be clipped, not shoved, to ensure good electrode
contact with the skin.
z
You may choose to use a skin treatment or preparation that is recommended
by your physician. Apply, let dry, and apply electrode as directed. This will
both reduce the chance of skin irritation and extend the life of your
electrodes.
z
Avoid excessive stretching of the skin when applying electrodes, this is best
accomplished by applying the electrode and smoothly pressing it in place
from the center outward.
z
When removing electrodes, always remove by pulling in the direction of hair
growth.
z
It may be helpful to rub skin lotion on electrode placement area when
wearing electrodes.
