General Safety Information
The information that follows, together with local site regulations, should be studied by personnel
concerned with the operation or maintenance of the equipment, to ensure awareness of potential
hazards.
Switch off
supplies before removing covers or disconnecting any RF cables, and before inspecting
damaged cables or antennas.
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 strong RF power may be present.
Users are strongly recommended to return any equipment that requires RF servicing to Silvus
Technologies.
CAUTION:
This system contains MOS devices. Electro-Static Discharge (ESD) precautions should be
employed to prevent accidental damage.

Health & Safety
Exposure to Non-Ionizing (RF) Radiation/Safe Working Distances
The safe working distance from a transmitting antenna may be calculated from the relationship:
D =
√
𝑃
𝑇
∙ 𝐺
𝑅
4𝜋 ∙ 𝑤
In which D = safe working distance (meters)
PT = transmitter or combiner power output (watts)
GR = antenna gain ratio = anti log (gain dBi ÷10)
w = power density (watts/square meter)
The RF power density value is determined by reference to safety guidelines for exposure of the human
body to non-ionizing radiation. 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 Silvus use, a maximum power
density limit of 1w/m² is to be applied when calculating minimum safe working distances.
Important Note:
It must be remembered that any transmitting equipment radiating power at frequencies
of 100kHz and higher, has the potential to produce thermal and a-thermal effects upon the human body.
To be safe:
a) Operators should not stand or walk in front of any high gain antenna such as dish antennas, nor should
they allow anyone else to do so.
