1 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.
WARNING- RF Power Hazard: High levels of RF power are present in the unit. Exposure to RF or
microwave power can cause burns and may be harmful to health.
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 RF power may be present.
Users are strongly recommended to return any equipment that requires RF servicing to RF Central.
WARNING- GaAs / BeO Hazard: Certain components inside the equipment contain Gallium Arsenide
and Beryllium Oxide that are toxic substances. Whilst safe to handle under normal circumstances,
individual components must not be cut, broken apart, incinerated, or chemically processed. In the
case of Beryllium Oxide, a white ceramic material, the principal hazard is from the dust or fumes which
are carcinogenic if ingested, inhaled, or entering damaged skin.
Please consult your local authority before disposing of these components.
CAUTION - Tantalum Capacitors: When subjected to reverse or excess forward voltage, ripple
current or temperature these components may rupture and could potentially cause personal injury.
CAUTION: This system contains MOS devices. Electro-Static Discharge (ESD) precautions should be
employed to prevent accidental damage.

1.1 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:
PT. G
R
D =
√
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 RF Central 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 100 kHz and higher, has the potential to produce thermal and athermal effects upon the
human body.
To be safe:
a) Operators should not stand or walk in front of any antenna, nor should they allow anyone else
to do so.
b) Operators should not operate any RF transmitter or power amplifier with any of its covers
removed, nor should they allow anyone else to do so.
FCC RF Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled
environment. The antenna(s) used for this transmitter must be installed to provide a
separation distance of at least 20 cm from all persons and must not be co-located or operating
in conjunction with any other antenna or transmitter. End users must follow the specific
operating instructions for satisfying RF exposure compliance.
********************************************************************************************************************
This device has been designed to operate with the antennas listed below, and having a
maximum gain of 8 dB. Antennas not included in this list, or having a gain greater than 8 dB
are STRICTLY PROHIBITED for use with this device. The required antenna impedance is 50
ohms.
