Safety Information
General Information
To ensure awareness of potential hazards, all personnel concerned with the operation or
maintenance of the equipment must study the information that follows, together with local site
regulations.
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.
WARNING: 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.
CAUTION: Users are strongly recommended to return any equipment that requires RF servicing to IMT.
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.
Disposal Instructions
WARNING: DO NOT incinerate batteries. Exposing batteries to naked flames or extreme heat sources can
cause them to rupture or explode.
DO NOT dispose of any of the supplied equipment as household waste. The supplied equipment is
not biodegradable in landfill sites. For safe disposal of the supplied equipment, take it to your local
(council/authority) environmental waste site. For details, contact your local authority/recycling
center.

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 =
in which D = safe working distance (meters)
PT = transmitter or combiner power output (watts)
GR = antenna gain ratio = anti log (gain dBi ÷10)
w = Maximum allowed 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 IMT use, a
maximum power density limit (w) of 1w/m² is to be applied when calculating minimum safe working
distances. Appendix A refers.
WARNING: 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:
•Operators should not stand or walk in front of any antenna, nor should they allow
anyone else to do so.
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.
Maximum RF Power Density Limits
The RF Radiation Power Density limit figure recommended by IMT is based upon guideline levels
published in:
•IEEE standard C95.1 1999 - IEEE Standard for Safety Levels with respect to Human
Exposure to Radio Frequency Electromagnetic Fields, 3 kHz to 300 GHz.
•Guidelines for Limiting Exposure to Time-varying Electric, Magnetic & Electromagnetic
Fields (up to 300 GHz) published in 1998 by the Secretariat of the International
Commission on Non-Ionizing Radiation Protection (ICNIRP).
Both documents define guideline RF power density limits for "Controlled" and "Uncontrolled"
environments. An uncontrolled environment is defined as one in which the person subjected to the
RF radiation may be unaware of and has no control over the radiation energy received. The
uncontrolled environment conditions can arise, even in the best regulated operations and for this
reason the limits defined for the uncontrolled environment have been assumed for the IMT
recommended limit.
Documents a) and b) also show the RF power density guidelines to be frequency dependent.
Different power density / frequency characteristics are presented in the two documents. To avoid
complexity and to avoid areas of uncertainty, IMT 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.
NOTE: The IICNIRP document is freely available for download from the internet at www.icnirp.de/emfgdl
(PDF file) the IEEE standard is available on loan from Essex County Library on payment of a search fee.
