Frequency therapy is easier to navigate when you have a clear purpose, know your device and introduce changes gradually. These recommendations bring together practical experience with zappers, the structure of the ETDFL list and useful guidance from the Resonant Light Technology manual. The earlier version also included specific schedules, examples of programme selection and an explanation of bodily responses. Those details are retained below, with the device, source and individual health situation made clear.
Start with one clear goal
First decide which physical condition, aspect of wellbeing or area of support you wish to focus on. Record your starting point, selected program, device, electrode type and session length. After a few days, this will make it easier to assess what suits you without changing too many variables at once.
If you are new to the device, choose one program and become familiar with how it feels to use it before adding others. The Resonant Light Technology manual also stresses a gradual start and keeping a record of programs and observations. Its instructions for the ProGen3 do not automatically apply to other devices.
The original distinguished simple zappers with one to three frequencies, often powered by a 9-volt battery, from more powerful programmable devices with a mains adapter. It suggested one session a day for beginners, two after a few days and, where appropriate, three or four later on. These were reported practices, not a universal schedule: the actual duration and frequency of use depend on the specific device instructions, how you feel and any health restrictions.
The author emphasised diagnosis, the choice of frequencies and lifestyle as parts of a broader approach. They described increased energy, circulation and well-being, along with evening or overnight use of accessories said to produce pulsed magnetic fields or so-called scalar waves. These are accounts of experience, not guaranteed outcomes or a reason to use contact electrodes while asleep.
The original considered it harder to overdo sessions with small battery-powered zappers, while still advising care for sensitive groups.
Choose frequencies and check the units
A fixed-frequency zapper and a programmable frequency generator are used in different ways. Hulda R. Clark’s historical protocol at 30,000 Hz, with a 7–20–7–20–7–20 sequence, describes one particular approach; it is not a universal rule for every device, program or health condition.
ETDFL (The Electro Therapy Device Frequency List) brings together named sets of ten frequencies. Find the relevant entry, check the edition of the list and enter the correct sequence into your device. Pay particular attention to units: if the source lists values in kHz, multiply them by 1,000 before entering them in Hz. The Slovenian edition on Zapper-Pro.si already gives the values in Hz. A disease or symptom name in the list labels a set; it is neither a diagnosis nor a guarantee of results.
Zapper-Pro 32 lets you save your own programs. Options include 30-minute programs with ten frequencies and nine-hour programs with a single frequency. Choose the program type according to your purpose and the device instructions. Check all ten entries before starting: a misplaced decimal point or confusion between kHz and Hz can completely change a setting.
The original described ETDFL as a regularly updated list and mentioned teams from twelve clinics, eleven researchers from five countries and thirty years of research. We retain those details as the author's account; for the current edition, contributors and use of an individual entry, consult the publisher at ETDFL.com.
The list contains thousands of named conditions, usually with ten frequencies per set. The original gave a set for the ‘common cold’ and a combination of several sets for more complex conditions as examples. Before dividing a longer set into five frequencies and another five a few hours later, check whether your device and its programme instructions permit this. Record the sequence, duration and units before starting.
With a preprogrammed zapper, follow its instructions and, where available, check the actual frequencies, waveform, positive or negative signal offset, and whether it runs on a battery or mains adapter. For devices allowing free entry, the older article proposed roughly 3–10 minutes per frequency in a set of ten, or 30–100 minutes for a full set, assuming a more powerful device required less time. That range is not a general rule for Zapper-Pro or other models.
Adapt your routine to the device and to yourself
Manufacturers’ manuals specify different program lengths, intervals and accessories. There is therefore no single duration or number of repetitions that applies to every zapper. Follow the instructions for your device and leave enough time between programs to rest and observe your response.
When using a multi-frequency list, keep the full program record and its units. Do not shorten, split or repeat programs simply because another device is used that way. In your notes, record the date, frequencies, duration, electrodes used and how you felt before and after use.
It makes sense to combine frequency-based support with the usual foundations of wellbeing: regular rest, suitable food, movement and normal fluid intake. If you feel tired or uncomfortable during use, reduce the load or take a break and check the settings. Marked or persistent symptoms call for appropriate medical assessment.
The original advice mentioned general programmes for parasites, colds, influenza, Candida, skin conditions, bacterial or viral infections and ‘detoxification’. It also quoted around 21–30 days for some problems, and shorter periods for colds and flu. These are historical suggestions for selecting and scheduling programmes, not established treatment times for an infection or another disease. If an infection is suspected, seek appropriate diagnosis and treatment.
‘Parasites, general comprehensive: Dr Clark’ was given as an example. Hulda R. Clark's 7–20–7–20–7–20 protocol means three seven-minute uses of 30,000 Hz, with two twenty-minute breaks. The original also cautioned that one frequency cannot remove all parasites in seven minutes; the protocol is therefore not presented as a substitute for testing or treatment.
Choose a suitable way to deliver the signal
Contact electrodes, including hand-held grips, gloves, socks and other parts of a dry electrode set, vary in how they feel and how much skin they touch. Check the connections, cleanliness and condition of your skin; adjust intensity and other settings according to the instructions for your particular device. Do not ignore unpleasant tingling or skin irritation.
Non-contact accessories such as F-Gen, S-Zapp and Tor-Gen are used differently and have their own limitations. Do not infer their properties from experience with contact electrodes. The companion article Important Information explains electrodes, situations requiring extra care and possible reactions in more detail.
Keep the broader picture in view with complex conditions
A frequency list helps you select programs; it does not replace understanding the cause of a problem. If symptoms are unclear or changing, do not assess them solely by a program name. A health condition may require diagnosis, monitoring and treatment, while frequency therapy can remain part of a personal supportive approach.
Over longer periods, comparing clearly documented programs is more useful than constantly changing frequencies. Track how you feel, any unwanted sensations and the questions you want to resolve. Progress cannot be confirmed by how a session feels, either during it or afterwards, alone.
For more serious conditions, the older text envisaged several frequency sets, adjustment over a number of weeks and regular use, sometimes for months. It mentioned the intestines, liver, kidneys, gallbladder and stomach, as well as lifestyle. Claims about killing pathogens, resonance with individual cells or success in serious diseases are part of the author's original explanation; a frequency list alone cannot establish such an effect in a particular person.
The original suggested considering a different set if nothing had changed after five days. A better first step is to check the frequency entry, settings, purpose and medical explanation of the symptoms. When a condition requires treatment, a frequency programme should not be a reason to delay medical care.
It especially proposed longer or repeated sessions in the evening before bed. This does not mean it is appropriate to fall asleep wearing contact electrodes.
Finding the right entry in a frequency list
When searching ETDFL, try reversing the word order or using a broader term: ‘skin cancer’ might be listed under ‘cancer, skin’, and ‘tapeworms’ under ‘parasites, tapeworms’. In a PDF, search for the first few letters of a key term and check related entries. If an entry is unclear, ask the list publisher or device manufacturer about the correct input and units.
For unclear symptoms, the original text also mentioned kinesiology or muscle testing, pendulums, and Vega and Quantum SCIO devices for selecting or testing frequencies. It referred to professional profiles and home use, for which knowledge of conventional medicine, traditional Chinese medicine and Ayurveda was said to be necessary. These methods are not reliable medical diagnostics; diagnosis and significant treatment decisions require appropriate clinical assessment.
Monitoring responses and the limits of personal experience
The author believed that regular use of an electrotherapy device could help people understand their bodies and select sets according to how they felt. They also suggested that, if a target microorganism was absent, a frequency would simply ‘fade’, while nearby frequency bands might affect other pathogens. A sensation or presumed resonance cannot establish whether an organism is present, and does not make every programme risk-free.
Record the programme, every value in Hz, duration, accessories and any changes in how you feel. Compare observations over time, but do not automatically interpret new or worsening symptoms as evidence that the programme is working. The companion article, Important information, explains reactions, electrodes and sensitive groups in more detail.
The original Recommendations' discussion of the Herxheimer or so-called detoxification reaction, including what to do if symptoms worsen, is retained in the companion article Important information.
What the original text emphasised
The original article presented frequency therapy as part of a regenerative approach. It attributed to it stem-cell activation, effects on consciousness and chakras, and possible effects on viruses, bacteria, cancer cells, organs, mood, healing and dementia prevention. These statements are retained as an account of the author's views, not as proof that electrical frequency programmes treat the conditions listed.
The guide remains open to exploring frequency-based approaches and programmable devices, while also calling for appropriate medical care in the event of serious symptoms or disease. Sources and further information on devices and frequency lists appear below.
