4 How does T.E.N.S. work? T.E.N.S. is simply a means of stimulating your body s own natural defences against pain. The unit produces a gentle stimulus through pads normally placed over the area of pain. This stimulus helps the body to produce natural pain relievers called endorphins, and to block the pain signal in its path to the brain. The correct positioning of the pads is important, so various body maps have been included to show pad positioning in order to achieve maximum relief. Many people feel immediate benefit from TENS. However a minority may only achieve benefit after repeated treatment sessions and over an extended period of time.

Do not place the TENS unit close to excessive heat 3. Use only the specified batteries: 2x 1.5volt AA Alkaline (LR6). Using of any other battery could damage the unit. 4. Remove batteries if unit is not to be used for a long period of time. 5. Do not use the unit while asleep. 6. Keep the unit away from sources of high magnetic fields such as TV S, microwave ovens and hi-fi speakers, as these may affect the LCD screen. 7.

The PADS The pads that are supplied with your EasySTIM TENS Pain Relief unit are self-adhesive and can be used several times. Skin must be allowed to breathe, so the pads should be removed periodically. When not in use, the pads should be placed onto the clear plastic shield. The condition of the pads does affect the conductivity and, therefore, the performance of the unit. When the pads initially lose their adhesive quality, it is possible to reactivate their adhesiveness by applying a fine spray of water. Once the pads have finally lost their adhesive quality. New Pads should be purchased Allergic reactions to the self adhesive pads can occur, even though they are hypoallergenic. Do not apply to broken skin Do not apply a pad to skin that does not have normal sensation. If the skin is numb, stimulation will not be felt and too great an intensity might then be used accidentally. BEFORE USE PLEASE READ THE FOLLOWING: T.E.N.S. SHOULD NEVER BE USED TO MASK OR RELIEVE UNDIAGNOSED PAIN. T.E.N.S. TREATS THE SYMPTOMS OF PAIN, SO IT IS IMPORTANT THAT A DOCTOR MUST DIAGNOSE THE CAUSE OF PAIN, BEFORE TREATMENT BEGINS.
