Lead Wires
Even with good care, lead wires will eventually develop breaks (open connections) simply from normal usage, and must
be replaced about every six months. Damage can occur due to jerking or pulling on the wires, excessive bending or tight
wrapping 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 lead
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 25 Series devices makes daily lead testing convenient. Damaged or worn leads should be discarded and replaced.
Instructions for testing are provided below.
DID YOU KNOW?
• Lead wires should be replaced at least every six months
• Carbon electrodes should be replaced approximately every six months
• Self-adhesive electrodes should be replaced aer no more than 15 uses
• You should never use monitoring electrodes nor ordinary TENS electrodes with this device
• Some brands of electrodes are of very poor quality or are inappropriate for electrotherapy. Your patient
may experience discomfort and even skin reaction due to poor distribution of current when using these
electrodes
• Failure to replace worn lead wires and carbon electrodes or using cheap, poor quality electrodes are some
of the most common causes of patient discomfort.
