Tens Clean Cote Skin Prep For Tens Electrodes To Prevent Skin RashPrepare the Skin

Clean skin is the best preventive against skin irritation so always wash skin at the application site with soap and water and pat dry with a towel. Never use alcohol, lotions, oils, or creams on the skin prior to placing the electrodes. Trimming (not shaving) body hair from the area is often helpful. Additionally, pre- and post-treatment skin care products protect the skin and help to keep the treatment area healthy. Should any irritation occur, discontinue treatment until the skin heals.


Use & Care of Reusable Infrex  & Tens Electrodes


Electrode Removal


Remove the electrodes from their liners by bending the liner slight at a corner. Loosen the gel from the liner by rubbing your thumb across the edge of the electrode in an upward motion. Once the gel has loosened from the liner, grasp the edge of the electrode and peel from the liner.


For those electrodes with pre-attached wires (or pigtails), PLEASE DO NOT PULL ON THE WIRE.Doing so will cause damage or destroy the electrode. The proper method of removal is to grasp the edge of the electrode and lift it from the liner or the skin.


Rotating Electrodes - Alternate Sets Every 6- 8 hours When Possible

To extend the life the electrodes, alternate their use. They should be swapped out every 4 to 6 hours if being used in a hot or humid environment with another set of fresh electrodes.



Over-saturation can occur if electrodes are worn too long without rotating. Over-saturation occurs when the solid gel electrode absorbs and retains moisture from perspiration, hot/humid environments, or excessive addition of water to re-hydrate the gel surface. Over-saturation results in an eventual lessening of the physical and adhesive properties of the gel. The electrodes should be removed from the skin and allowed to air dry in a cool and dry environment such as a refrigerator, with the gel exposed to the air for at least 24 hours.


Storing & Re-hydrating

Always check to electrode gel for tac prior to use. If the gel does not readily adhere to a gentle touch of your fingertip, rub a drop of water on the gel surface and repeat until the surface has been completely re-hydrated.


Return the electrodes to the release side of their liner and return to the storage bag. Store in a cool, dry place, avoiding exposure of the gel to heat and humidity.


Rechargeable 9 volt tens batteryBattery Care

To prolong battery life of rechargeable batteries, discharge the battery completely before re-charging to full capacity. Place the battery in the charger and charge for 12 to 14 hours. After charging, remove the battery. DO

NOTstore the recharged battery in the charger.


Lead Wire Care

The lead wires can become discolored and brittle from the effects of skin oils, perspiration, etc. To help keep lead wires clean and to help retain flexibility, cleaning daily with mild soap and water is suggested.


Connectors for tens cables and tens supplies, Infrex Plus pain machine cablesPin Connectors

When using pin connectors, place the connectors horizontally to prevent detachment or excessive strain with movement. Be sure that no bare metal is exposed. Twisting the pins in and out of the electrode aids in full insertion and easier removal.


The Importance of Water

To achieve the best results, it is important to stress that the patient be hydrated. The absence of proper fluid levels in body tissue may cause conductivity to be partially or totally blocked. Water is the recommended liquid, as beverages such as coffee, tea, and cola act as diuretics and actually rob the tissues of fluid.
