TECHNICAL SPECIFICATIONS

DEVICE SPECIFICATIONS

  • Caution: U.S. Federal law restricts this device to sale by or on the order of a physician. In other words, if you live in the U.S. you need a prescription to purchase The Fischer.
  • The Fischer may only be powered by the adapter provided, which has been specially designed for this device. The use of non-original parts may be hazardous to the user and even lead to death. Use of accessories, transducers and cables other than those specified or provided by the manufacturer of this equipment could also result in increased electromagnetic emissions or decreased electromagnetic immunity of this equipment and result in improper operation. Using non-original spare parts and accessories immediate voids warranty.

  • Use of this equipment adjacent to or stacked with other equipment should be avoided because added pressure could result in accidental damage. If stacking of equipment becomes necessary, The Fischer and any other equipment should be observed to verify that they are operating normally.

  • Place The Fischer and water bath trays on a firm, level surface.

  • Please always cover the treatment electrodes with the foam inserts or sponge pads provided; otherwise, you might risk burns (electrical burn injuries, current marks). Avoid direct contact with the electrodes.

  • Do not use the wearable parts (foam inserts and sponge pads) for more than 18-months and replace them on time.

  • Make sure that The Fischer is stored at room temperature before you power it up. Depending on storage conditions, the temperature adaptation may take up to 2 hours.

  • Prior to starting a treatment session, please remove any metallic jewelry (rings, watches, bangles etc.), as electric current concentrations in these regions might result in minor injuries (local electrical burns, current marks).

  • Any small skin lesions or breaks must be covered with petroleum jelly (Vaseline) to insulate them from the current flow.

  • Depending on the current strength selected, users may experience tingling or stinging sensations (discomfort) during the treatment.

  • If the current is set too high, you may experience painful sensations all over the treated extremities.

  • You may remove your hands or feet safely from the treatment trays any time. In very rare cases, unpleasant electric shocks may occur; these are, however, absolutely harmless.

  • During the first treatments, you may experience increased sweat production; these symptoms will spontaneously abate after the next few treatment sessions.

  • The treated skin can show signs of dehydration like flaking or small lesions. Should this be the case, please apply a rehydrating cream after treatment.

  • Immediately following a treatment session, occasional redness may be observed. This is temporary and a sign that the treatment is working (stimulating capillaries). In rare cases, blistering may occur. Reducing the treatment intensity can minimize the appearance of these symptoms. Before administering a new treatment session, the skin has to heal completely. In case of an unexpectedly strong skin reaction, a medical professional must be consulted before further treatments are administered.

  • You may not be treated by two devices simultaneously. The device may not be modified.

  • Keep out of reach of children unless otherwise supervised. Do not leave the device unattended. Risk of strangulation and injuries.

  • Portable RF communications equipment (including peripherals such as antenna cables and external antennas) should be used no closer than 30 cm (12 inches) to any part of the device, including cables specified by the manufacturer. Otherwise, degradation of the performance of The Fischer could result.

  • Follow the recommended separation distances listed in appendix 1.

  • Disconnect the power supply from the socket if a thunderstorm approaches or if you do not plan to use The Fischer for an extended period of time.

  • Position the device so that you can unplug the power supply unit from the socket anytime.

  • The Fischer is designed for indoor use only. Do not expose it to rain or humidity.

  • If you wish to clean The Fischer, pull all plugs from the socket and switch it off. Use a soft, damp cloth and a mild cleaning solution to clean the device.

  • Make sure you do not pull the cable too hard and do not expose the cable to heat or chemicals. If a cable is damaged, unplug it from device or electrode, respectively, and have it checked by RA Fischer Co.

The device may only be used with the power supply unit that corresponds with the power supply specified on the rating plate. To ensure safe operation The Fischer, all its cables, plugs, control elements and housing components must be in faultless condition. Prior to each use, check the device for possible damage; a defective unit should not be used for treatment. Pay attention to the references on the unit and in this user manual. Switch the unit off after each treatment session.

The Fischer is a Tap Water Iontophoresis (TWI) device intended to treat hyperhidrosis (pathological sweating) affecting hands, feet, underarms, or all three. Any other use or usage beyond this scope is considered un-intended use and may have dangerous consequences.

The Fischer is intended to be used in closed rooms. Allow the device to reach room temperature before conducting a treatment. The Fischer may only be used in a dry environment. The required minimum distance to shortwave microwave devices depends on their frequency and transmission power and is defined in the Electromagnetic Compatibility tables. For additional information, please refer to item 9 “Initial Operation” in the user manual.

 

When starting treatment, sessions should be performed four times per week and not more than once daily for approx. 15-minutes each. After about 10 treatments, sweat secretion decreases to normal levels. Due to the reversible character of the therapy, a long-term treatment (maintenance schedule) is indicated with sessions lasting approx. 15-minutes, to be conducted once or twice per week, depending on the severity of the clinical symptoms. 

 

Any use beyond this scope is considered “not according to intended use.” The manufacturer cannot accept any responsibility for personal injury or material damage that is or might be caused by usage beyond the scope of “intended use.”

Under no circumstances should Iontophoresis be performed if any of the following applies:

  • User/s with a pacemaker
  • User/s with an implanted cardioverter defibrillator (ICD)
  • Pregnancy
  • Metal-containing intrauterine pessary (only relevant in case of feet treatment)
  • Metallic implants present in the current path (hands or feet)
  • Large skin defects / wounds that cannot be covered with Vaseline
  • Any area where sensation is absent or impaired (e.g. polyneuropathy)
  • User/s with palpitations (cardiac arrhythmia)
  • User/s with seizure disorders (epilepsy)
  • User/s with potentially malignant lesions, acute localized infections, skin eruptions, or swollen, broken, or inflamed areas
  • User/s with severe local inflammation or thrombosis (blood clots)
  • User/s with severe vascular disorders

The following side effects may occur:

  • A tingling and burning sensation during the treatment caused by excessive current settings or open areas of the skin
  • Slight, but harmless, shocks when treatment is interrupted
  • Dry skin after the treatment
  • Short-term reddening of the skin following the iontophoresis treatment, caused by a stimulated circulation (hyperemia), amongst others
  • Blistering and electric burns caused by excessively high current strength

Should you encounter any errors prior to, during, or after a treatment session, please work through this troubleshooting checklist before contacting RA Fischer:

  • Verify that the power supply cord is properly connected to the control unit and your power The green LED on the power supply cord should be lit.
  • Verify that the plugs on the electrode cables have been pushed all the way into the control unit and silicone-graphite
  • The current will only boot up to the selected current level if treatment time has been set to more than 1 minute and the settings have been confirmed by pushing the SET-button once and the skin areas to be treated have closed the treatment

Rule out a device defect:

Verify that The Fischer is working by testing it without any body resistance. Prepare a water bath tray for the hand treatment as described above. Now, instead of a hand, place the second silicone-graphite electrode on the foam insert (moistened with water) and set the polarity switch to automatic. Now check the main control unit: is the timer counting down? The energy symbol flashing?
If YES, than the treatment is working and The Fischer is working properly. So why is the treatment not working when you try it? Your body resistance may be too high, or you may life in a “soft water” area, meaning your tap water lacks the mineral concentration that makes iontophoresis possible. Here’s what you can do:

  • Determine body resistance
    The first step is to make sure that your skin is free of oily or greasy residue from creams, cosmetics, or cream soaps. Second, make sure the water level is sufficient. Try once more to perform the treatment on your hands. Should the device still not start automatically, ask someone else to perform the treatment on him/herself. If the device works properly for another person, your personal body resistance is too high and the device does not start for safety reasons.
  • Determine water resistance
    If the device does not start properly for another person, you may live in a “soft water” area and the water resistance is probably too high. In place of using tap water, pick up a bottle of distilled mineral water or table water from your local grocery store and re-try the treatment. Additionally, you can use a very thin fleece or sponge cloth in place of the blue foam inserts over the silicone- graphite electrodes. This will reduce the water path and thus the resistance.

In case of a device failure, or if the actions mentioned above are unsuccessful, please contact RA Fischer Co. by phone. (800) 525-3467
