Frequently asked questions

Everything people most often ask us about CMO technology, choosing the right protection, and ordering across Australia and New Zealand. Can't find your answer? Ask a free AI assistant, or contact us directly.

What is CMO technology and how does it work?

CMO (Compensating Magnetic Oscillator) technology is a French-made EMF-mitigation system. Each device contains a programmed microcrystalline solution, activated by incoming electromagnetic radiation, that generates a hyper-weak 12 Hz compensation signal designed to help your cells cope with EMF exposure — without blocking or weakening your devices' signals.

Is CMO EMF protection scientifically proven?

CMO technology is supported by 24 independent, peer-reviewed studies conducted across five countries and validated by university professors and doctors of medicine. The research measures improvements in biomarkers that electromagnetic fields are known to disrupt. See The Science for the full story.

Will CMO products stop my phone or Wi-Fi working?

No. CMO technology mitigates the biological effects of EMFs without blocking the signal, so your phone, Wi-Fi and other devices keep working exactly as normal.

Do CMO devices need batteries, charging or maintenance?

No. CMO devices are passive — they need no electricity, batteries or maintenance. They self-activate in the presence of the ambient electromagnetic fields already around you.

Which CMO product is right for me?

Match the CMO to the source of exposure:

  • Easycall MP24 — sticks onto the phone or tablet you hold against your body.
  • PCZone PC16 — sticks onto your laptop or computer.
  • Traveller TR26 — worn or carried for protection out and about.
  • Harmony MF04 — whole-home protection, around 100 m².
  • Harmony XL MF05 — larger homes and offices, around 200 m².
  • Aircall SP21 — air-tube earphones that keep speaker electronics away from your head.

Many customers combine an Easycall, a PCZone and a Harmony for full coverage. Not sure? Ask us for a recommendation.

How large an area does a Harmony cover?

The Harmony MF04 is sized for a home of around 100 m², and the Harmony XL MF05 covers a larger space of around 200 m² — ideal for larger homes, offices, schools and animal barns. Coverage is indicative (RAC method), not a precise measurement.

Can I measure CMO working with an EMF meter?

No — and we would rather say so plainly. An EMF meter such as the TriField TF2 measures field strength, and CMO technology does not reduce field strength. It works on the biological effect of the fields, which no meter can display. If you take a reading before and after installing a CMO, the number will be the same. That is the technology working as designed.

A meter is still worth owning: it shows you where the strongest fields are, so you can move away from them — the cheapest protection there is.

Do you sell EMF meters, and do you offer bulk pricing?

Yes. We stock the TriField TF2 — an AC magnetic, AC electric and RF meter in one instrument, made in the USA by AlphaLab — at A$449 GST included.

We also supply schools, clubs, associations and workplaces at bulk pricing, and qualifying group orders include a TriField TF2 at no charge. Email support@comosystems.com.au for a quote.

Where do you ship, and how can I pay?

We ship right across Oceania — Australia, New Zealand and the Pacific — with tracked delivery. Prices are in Australian dollars (AUD) with GST included, and checkout is handled securely by Stripe with Visa, Mastercard, Apple Pay, Google Pay, Klarna and Zip.
