To Restore Adhesiveness:
• Before a Treatment: Before placing the electrode on patient, moisten the patient’s skin
with a damp cloth using plain water, then apply the electrode to the skin.
• After a Treatment: Spray the adhesive side of the electrode with plain water, rub it
lightly with fingertips, then reapply the electrode to its plastic backing and seal it tightly
in its storage pouch. Do not use an electrolyte spray to remoisten self-adhesive
electrodes as this substance can destroy the adhesive.
With this method of rehydration, after a couple of hours electrodes can regain up to 90
per cent of their original adhesive quality.
2. NEVER use a self-adhesive electrode for more than 15 treatments (maximum).
3. NEVER use STRAPS, weights, or other devices to attach self-adhesive electrodes to
the skin. If an electrode has lost its adhesive quality, you can use one of the methods
given above to rehydrate the adhesive, or you should discard the electrode. Using
straps and weights with self-adhesive electrodes could have an unpredictable effect
on the electrodes and could cause injury.
Combination Treatment Usage Cautions
When delivering combination ultrasound and stim treatments delivering stim current through
the soundhead, the following are the recommended maximum stim intensities (refers to
premodulated, biphasic or Russian stimulation only):

Lead Wires
Even with good care, lead wires will eventually develop breaks (open connections) simply
from normal usage, and they must be replaced. Lead wires have a limited lifetime and
must be replaced about every six months. Lead wires can be damaged due to jerking or
pulling on the wires, excessive bending or tight wrapping of the wires, or running over the
wire with a device cart. When setting up treatments, keep lead wires out of areas where a
person could trip on them. When storing, lead wires should be loosely wrapped to prevent
any kinking in the wire. Never use worn or damaged leads to treat a patient. Using faulty
leads may result in injury to a patient.
Test Leads Daily. Lead wires should be tested regularly to ensure they are functioning
properly and safely. A simple test performed with the Dynatron 850plus and 550plus makes
daily lead testing convenient. Damaged or worn leads should be discarded and replaced.
Under normal use, leads should be replaced about every 6 months. Instructions for testing
are provided below.
Remove Corrosion From Lead Tips. Lead tips will build up corrosion through use. The
lead tips must be cleaned and kept free of this corrosion in order to function correctly. To
