This unit must be used with the guidance of a Physiotherapist or Doctor. Type BF equipment, Continuous Operation Do not insert lead wires into a mains power supply. Do not immerse unit into water or any other substance. Do not use the NeuroTrac™ PelviTone unit in the presence of a flammable anaesthetic gas mixture and air or with Oxygen or Nitrous Oxide. If using rechargeable 9 Volt PP3 Nickel Metal Hydride batteries, be sure to use a CE approved battery charger. Never connect the NeuroTrac™ PelviTone directly to a battery charger or to any other mains powered equipment. We advise not to use Ni-Cad rechargeable batteries. Patient Electrodes are for single patient use only. Keep out of reach of children. Do not use this stimulator on your facial area unless you are under strict guidance from a qualified Clinician. Application of electrodes near the thorax may increase the risk of cardiac fibrillation. Operation in close proximity (e.g. 1m) to a shortwave or microwave therapy quipment may produce instability in the stimulator output. Simultaneous connection of a patient to a high frequency surgical equipment may result in burns at the site of the stimulator electrodes and possible damage to the stimulator. No modification of this equipment is allowed!

NeuroTrac™ PelviTone Operation Manual
What is STIM? Neuromuscular Stimulation has been used for many years to stimulate muscle and nerve fibres to treat a number of muscle and nerve related conditions. Over the last 30 years numerous clinical trials and papers have been written. The NeuroTrac™ PelviTone is one of a new breed of modern Neuromuscular Stimulators which Verity Medical have developed with the Therapist and Patient in mind. Our principle aim is to design products that have high levels of functional use, are sensibly priced, compact and user friendly. The NeuroTrac™ PelviTone is a dual channel device combining several treatment programmes into one unit. Neuromuscular Stimulation is increasingly understood by Therapists and Doctors. There is a better understanding of the mechanisms which exist between nerves and muscles that makes it possible to stimulate the neuromuscular system with precise electrical signals. The NeuroTrac™ PelviTone offers precision giving full control of Pulse Widths, Rates, Ramp up times, Work / Rest cycles as well as alternating or synchronous application if two channels are being applied. Customer Care We welcome constructive comments regarding our equipment particularly those that might help us to improve existing features, add new ones or develop new products for the future.

This programme is to help relax the pelvic muscle. It may be used where the EMG readings are high, in the region of 8 microvolts or more or when the pelvic muscle has been working hard and some fatigue may have resulted. The very low 2 Hz frequency will help to relax the muscle.

A Few Good Tips [Self- Adhesive Electrodes] *
* *
If you find the electrodes will not stick due to oily skin, cleanse the skin with soap and water, then rinse and dry the area around the electrode site. If this does not work, try cleansing the skin with a swab impregnated with alcohol. Clip away hairy skin using scissors; don’t use a razor to remove the hairs! The electrodes conductive material is water- based. If it becomes saturated (e.g. from perspiration), it will lose its adhesive qualities. After use leave the electrodes face up overnight to dry out (replace on plastic film in the morning). At some point the electrodes will become dry. Moisten the adhesive surface with a few drops of water, and apply onto the plastic film overnight. This procedure will increase the electrode life by few more days. 17
