SAFETY
1.1
Purpose
The Myo 200 is intended solely for medical applications. You can use the Myo 200 for electrotherapy and re-education. For re-education the feedback signal is measured, if chosen in combination with an electrotherapy stimulation. The device is suited for continuous use.
1.2
Safety instructions
1.2.1
General
• Only qualified people who are trained in the application of the therapies may use the appliance.
• Only a technician authorised by GymnaUniphy N.V. may open the equipment or the accessories.
• Follow the instructions and directions in these user instructions.
• Place the device on a horizontal and stable base. • Keep the ventilation openings at the bottom and rear of the equipment free.
• Do not place any objects on the equipment. • Do not place the equipment in the sun or above a heat source. • Do not use the equipment in a damp area. • Do not let any liquid flow into the equipment. • Do not disinfect or sterilise the equipment. Clean the equipment with a dry or moistened cloth. See §5.
• Only treat patients with electrical implants (pacemaker) after obtaining medical advice.
• The 'Directive on Medical Devices' from the European
•
•
Commission (93/42/EEG) requires that safe devices are used. It is recommended to perform a yearly technical safety inspection. See §5.1.1. For optimum treatment, a patient investigation must first be performed. On the basis of the findings of the investigation, a treatment plan with objectives will be formulated. Follow the treatment plan during the therapy. This will limit possible risks, related to the treatment, to a minimum. Always keep these user instructions with the equipment.

1.2.2
Electrical safety
• Only use the equipment in an area with facilities that meet the applicable legal regulations.
• Connect the equipment to an outlet with a protective earth terminal. The outlet must meet the locally applicable requirements for medical areas.
1.2.3
Prevention of explosion
• Do not use the equipment in an area where combustible gases or vapours are present.
• Switch off the equipment when it is not used. 1.2.4
Electro Magnetic Compatibility
• Medical electrical equipment requires special precautions for • • •
Electro Magnetic Compatibility (EMC). Follow the instructions for the installation of the equipment. See §2. Do not use mobile telephones or other radio, shortwave, or microwave equipment in the vicinity of the equipment. This kind of equipment can cause disturbances. Because the Myo200 is intended to measure extreme small potentials, its immunity level for electromagnetic radiation is lower then 3V/m. See §8.3.1 for detailed information. Only use the accompanying accessories that are supplied by GymnaUniphy. See §7.6 and §7.7. Other accessories can lead to an increased emission or a reduced immunity.

1.2.5
Electrotherapy
• Do not use the equipment simultaneously with high frequency •
• • •
• 1.3
surgical equipment. This combination can cause burning of the skin under the electrodes. Do not use adhesive electrodes with currents that have a galvanic component, such as galvanic, diadynamic, MF rectangular, pulsed rectangular and triangular currents. With these currents, etching of the skin can occur. Application of electrodes near the thorax may increase the risk of cardiac fibrillation. Check the electrode cables, the electrodes and the probes at least once a month. Check whether the insulation is still intact. See §5.1. The safety standards for electrical stimulation advise not to exceed the current density of 2.0 mArms/cm2. However, with iontophoresis treatments, we advise a maximum current density of 0.25 mÂ/cm2, because of using the MF rectangular current. Exceeding this value can result in skin irritation and burns. Always use sterilised gauze with iontophoresis treatments.
Medical Devices Directive
The device complies with the essential requirements of the Medical Device Directive of the European Committee (93/42/EEC) as most recently changed. The device contains no human or animal tissue, no medical substances, and no blood or blood products from human or animal origin.
1.4
Liability
The manufacturer cannot be held liable for injury to the therapist, the patient or third parties, or for damage to or by the equipment used, if for example: • an incorrect diagnosis is made; • the equipment or the accessories are used incorrectly; • the user instructions are wrongly interpreted or ignored; • the equipment is badly maintained; • maintenance or repairs are performed by people or organisations that are not authorised to do so by GymnaUniphy. Neither the manufacturer nor the local GymnaUniphy dealer can be held liable, in any way whatsoever, for the transfer of infections via the vaginal, anal and rectal probes and/or other accessories.

2.2
INSTALLATION Receipt Check whether the equipment has been damaged during transport. Check whether the accessories are intact and complete. See §7.6 and §7.7. • Inform your supplier of any damage or defects by no later than within 3 working days after receipt. Report the damage by telephone, fax, e-mail or letter. • Do not use the equipment if it is damaged or defective.
Placing and connection
1.
Place the device on a horizontal and stable base. • Keep the ventilation openings at the bottom and rear of the equipment free. • Do not place the equipment in the sun or above a heat source. • Do not use the equipment in a wet area.
2.
Check whether the mains voltage that is stated on the rear of the equipment corresponds with the voltage of your mains supply. The equipment is suited for a nominal mains voltage from 100 V to 240 VAC / 50-60 Hz. Connect the device to an outlet with protective earth terminal.
