BodyMed ZZAIF400 Digital Interferential Unit

Includes:

• Unit
• Carrying Case
• 2 Lead Wires
• 4 Electrodes (1 Pack)
• 9-Volt Battery
• 9-Volt AC Adaptor
• Operation Manual

Warnings:

• This device must be kept out of reach of children.
• The safety of the device for during pregnancy or delivery has not been established.
• Do not place electrodes on front of the throat. This may result in spasms of the laryngeal and pharyngeal muscles.
• Do not place electrodes over the carotid nerve (the front and sides of the neck).
• This device is not effective for headaches.
• Caution should be used when applying the device to patients suspected of having heart disease. Further clinical data is needed to show if there are adverse side effects on those with heart disease.
• The device may interfere with electronic monitoring equipment, such as ECG monitors and ECG alarms.
• There devices have no curative value. The interferential is a symptomatic treatment that suppresses the sensation of pain which would otherwise serve as a protective mechanism.
• Interferential devices should be used only under the continued supervision of a physician or licensed practitioner.
• Do not use on broken shin.
• Effectiveness is highly dependent upon patient selection by a person qualified in pain management.
• If the device treatment becomes ineffective or unpleasant, stimulation should be discontinued until re-evaluation by a physician or licensed practitioner.
• Always turn the device off before applying or removing electrodes.
• The device does not have AAP/APG protection. An explosion hazard is possible if used in the presence of explosives, flammable materials, or flammable anesthetics.

Adverse Reactions

• Skin irritation and electrode burns are potential adverse reactions. Stimulation should be stopped and electrodes removed until the cause of the irritation or burns can be determined.
• Isolated cases of skin irritation may occur at the site of electrode placement following long-term application. Always properly clean skin before use. If skin irritation occurs, discontinue use. Do not resume use of the ZZAIF400 unit until you have seen your physician or licensed practitioner.

Functions:

• Output Parameters: There are nine modes: five modes with Frequency Shift, three modes with Auto Sweep, and one mode that is fully adjustable.
• Constant Mode: Maintains set frequency (SET: bps can be adjusted)
• Auto Sweep: Modulates frequency between the range that is selected. For example, select 80 – 145 bps Auto Sweep model. The modulation range of pulse frequency is from 80 – 145 bps. The Sweep Time is 15 seconds and then. There are three modes of Auto Sweep:
• 80 – 145 bps
• 4 – 45 bps
• 4 – SET bps
• Frequency Shift: There are five modes:
• 1/1 abruptly shift: The pulse frequency varies from -30% to +60% of the set pulse frequency. One second at the lower frequency, and one second at the higher frequency. The transition is abrupt (square wave function).
• 6/6 abruptly shift: The pulse frequency varies from -30% to +60% of the set pulse frequency. Six seconds at the lower frequency, and six seconds at the higher frequency. The transition is abrupt (square wave function).
• 6/6 ramped shift: The pulse frequency sweeps from -30% to +60% of the set pulse frequency. Six seconds from the lower frequency modulate to the higher frequency, and six seconds from the higher frequency modulate to the lower frequency. The transition is ramping (triangular wave function).
• 10/10 abruptly shift: The pulse frequency varies from -30% to +60% of the set pulse frequency. Ten seconds at the lower frequency, and ten seconds at the higher frequency. The transition is abrupt (square wave function).
• 10/10 ramped shift: The pulse frequency sweeps from -30% to +60% of the set pulse frequency. Ten seconds from the lower frequency modulate to the higher frequency, and ten seconds from the higher frequency modulate to the lower frequency. The transition is ramping (triangular wave function).
