Just as the frequency spectrum of sunlight regulates the production of Vitamin D and melatonin and causes pigmentation, there are countless other frequencies that trigger regulatory mechanisms in organisms. Based on the principles of bioresonance, it is found that while we are weakened by long-term exposure to geopathic stresses and man-made electromagnetic fields (EMFs), there are fundamental frequency values that provide a strengthening, compensatory effect. These values have been integrated into dipole antenna systems within the Duplex IV and accompanying Rayonators. Together they emit harmonising energy that strengthens us to environmental stresses in a large area.

The Duplex IV particularly strengthens us to geopathic stresses from underground water veins, fault lines and global grids. When connected to the E-smog and HF Rayonators, the Duplex IV amplifies the emission range of the Rayonators and together they provide us with greater protection against EMFs.

Due to its unique design, the Duplex IV has a vast coverage (exact area varies with environmental factors) and is generally adequate for most Hong Kong homes. The set should be placed on the floor or the lower level of any duplex flats or houses as the frequencies rise upwards to a height of 8 metres. It may be placed near or in the bedroom to help balance electromagnetic and geological influences during rest when repair is most active within the body.

The Duplex Set is not powered by electricity. No maintenance is required. It should be cleaned by a moist cloth to prevent accumulation of dust, dirt and static. The set can be used continuously provided the devices are not broken with a loosening of the dipole antennas inside.
