1. General Information
1.1. General Safety 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: We strongly recommended that you return any equipment
requiring RF servicing to Vislink.
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.
1.2. 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.
NOTE: In Europe dispose of all equipment in accordance with the
European Environmental directive.

1.3. Environmental
CAUTION: The unit is IPxx rated and must be protected from dripping or
splashing water/fluids. When used outdoors, protect the unit
using a rain cover.

1.4. 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 Vislink
use, when calculating minimum safe working distances, apply a maximum
power density limit (w) of 1w/m². 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:
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.

1.5. Maximum RF Power Density Limits
The RF Radiation Power Density limit figure recommended by Vislink is
based upon guideline levels published in:
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-Ionising 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 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 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.

The modulator operates as one of three main types:
1. Single Pedestal LMST(S)
2. Dual Pedestal LMST(D)
3. DVB-T
Modulation options are selected in the MODULATOR > Modulation menu.
Here, you select either LMST or DVB-T.
Select the Bandwidth from MODULATOR > Bandwidth menu.
NOTE: In LMST(D) mode, the bandwidth shown is the combined width of
the two pedestals.

The LMST bandwidths:
•Single Pedestal:
−3, 4, 5, 6, 7, 8, 10, 12 MHz
NOTE: Without a variable bandwidth license, only 10MHz is available.
•Dual Pedestal:
−6, 8, 10, 12, 14, 16, 20 & 24 MHz
NOTE: Without a variable bandwidth license, only 20MHz is available.
The DVB-T bandwidths:
•6, 7 & 8 MHz
