HHT3 Operators Manual

General Information

Issue :No. 7b Page : 1

Personnel concerned with the operation or maintenance of the equipment described must

study the following information, together with local site regulations. This is to ensure

awareness of potential hazards.

WARNING: 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.

WARNING: To avoid RF radiation or electric shock: switch off all power supplies before

disconnecting any RF cables or antennas 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.

WARNING: We strongly advise that you return any equipment that requires RF servicing to

Vislink (Gigawave).

WARNING: GaAs / BeO Hazard: Certain components inside the equipment contain Gallium

Arsenide and Beryllium Oxide that are toxic substances. While safe to handle

under normal circumstances, do not cut, break apart, incinerate or chemically

process individual components. 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 enter via damaged skin.

Please consult your local authority before disposing of the following components:

WARNING: 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. To prevent accidental damage, employ

Electro-Static Discharge (ESD) precautions.

CAUTION: The Handheld Receiver does not contain user serviceable parts. Return the unit

to Vislink Customer Support for any repairs required.

CAUTION: Do not open the main unit.

CAUTION: Do not expose the Handheld Receiver to dripping or splashing water/liquid. You

should use the (normally) supplied rain cover, when using the unit outside.

CAUTION: Only replace the external battery with the same or equivalent type.

WARNING: Do not expose the battery to excessive heat, such as fire or the like.

No equipment, including batteries where applicable, should be disposed of with household

waste, as they are not biodegradable in landfill sites.

HHT3 Operators Manual

General Information

Issue :No. 7b Page : 2

WARNING: Do not incinerate batteries.

For safe disposal take to:

The local (council/authority) environmental waste site (in Europe in accordance with

the European Environmental directive).

For local battery disposal information, contact your local authority/recycling center.

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. The guidelines adopted differ throughout the

world and are revised from time-to-time. For Vislink (Gigawave) use, a maximum power

density limit (w) of 1w/m² is applied when calculating minimum safe working distances.

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 work safely:

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 receiver or power amplifier with any of its

covers removed, nor should they allow anyone else to do so.

4.w

HHT3 Operators Manual

General Information

Issue :No. 7b Page : 3

a. 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.

b. 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 Vislink (Gigawave) 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, Vislink (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.

The IICNIRP document may be freely downloaded from the internet at

http://www.icnirp.org/cms/upload/publications/ICNIRPemfgdl.pdf (PDF file). The IEEE

standard may be available on loan from your local County Library on payment of a search

fee.
