    Avoid standing in front of high gain antennas (such as a dish) and never look into the open end of a waveguide or cable where RF power may be present. Users are strongly recommended to return any equipment that requires RF servicing to Gigawave. WARNING- GaAs / BeO Hazard: Certain components inside the equipment contain Gallium Arsenide and Beryllium Oxide that are toxic substances.

  • Page 5: Health & Safety

    It is important to note that the guidelines adopted differ throughout the world and are from time-to-time re-issued with revised guidelines. For Gigawave use, a maximum power density limit (w) of 1w/m² is to be applied when calculating minimum safe working distances.

  • Page 6: Maximum Rf Power Density Limits

    Different power density / frequency characteristics are presented in the two documents. To avoid complexity and to avoid areas of uncertainty, Gigawave recommends the use of a single power density limit across the frequency range 100 KHz to 300 GHz. The 1w/m² power density limit we recommend satisfies the most stringent of the guidelines published to date.
