Warnings
• The long-term effects of chronic electrical stimulation are unknown.
• The Orthosis should not be applied over swollen, infected, or inflamed areas
or skin eruptions, e.g., phlebitis, thrombophlebitis, varicose veins, etc.
• Simultaneous connection of the L300™ to the patient and to high-frequency
surgical equipment may result in burns at the site of the stimulator
electrodes and possible damage to the RF Stim Unit of the Orthosis.
• Do not use the NESS L300™ in close proximity (less than 3 feet) to short
wave or microwave therapy equipment as it may produce instability in
the RF Stim Unit output.
• System configuration should only be performed by an authorized
clinician.
Precautions
• Inflammation in the region of the NESS L300™ may be aggravated by
motion, muscle activity or pressure from the Orthosis. Use of the device
should be temporarily halted until the inflammation clears.
• Caution should be used for patients with suspected or diagnosed heart
problems.
• Caution should be used in the presence of the following:
o When there is a tendency to hemmorage following acute trauma
or fracture.
