3. Safety Information
3.1. 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 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.
3.2. 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 lanMLT3ill 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.
3.3. 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.

Safety Information
M55-ML3-UG, Rev A 8
3.4. 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, 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.

M55-ML3-UG, Rev A 9
3.5. Maximum RF Power Density Limits
The RF Radiation Power Density limit figure recommended by VISLINK 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 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 (PMLT3 file) the IEEE standard is available on loan from
Essex County Library on payment of a search fee.

4. Introduction
The Microlite 3 Transmitter is a wireless video transmission system designed to capture
real-time, high-quality video from cameras for sports, live and remote production (REMI),
applications. The MicorLite 3’s low power consumption and small size make it an ideal
solution for production and PoV cameras as well as drone, robitic and mobile solutions.
The transmitter features HD/SD-SDI and HDMI inputs with COFDM transmission in a small,
lightweight chassis. The Microlite 3 delivers up to 200mW of power in a small package,
providing long range, reliable HD video transmission.
The Microlite 3 is a compelling choice when video quality, exceptional range and reliability
are required. Vislink’s COFDM technology ensures the transmission of uninterrupted, live
pictures over long ranges, despite the effects of foliage, challenging terrain, buildings and
other common non line-of-sight limitations. This gives it a significant advantage over
uncompressed solutions.
The Microlite 3 may be configured or remotely controlled by the built-in Wi-Fi
webserver. An Android or iOS device will see the Microlite 2 and allows to control the
device through web browser. A 900MHz transceiver enabling processing of remote
commands including camera control is optional.

5.3. Power Consumption
The MLT3 features extremely low power consumption. In addition, the MLT3’s hibernate
mode is specifically designed to save battery power when not being used. This mode lets
the MLT3 power down to all but the minimum required circuitry to listen for instructions.
Hibernate to full power takes less than 12 seconds.
5.4. Wi-Fi Controller
The MLT3 features a Wi-Fi transceiver for external status, control and configuration via
an iOS or Android device. Controls include:
•Transmitter status
•On/Off/Hibernate
•Product Information
•Channel, modulation and, Constellation Control
•Frequency Plan Update
•Optional 900 MHz Control
5.5. Transmitter Electrical Description
The transmitter is a two-board solution, with a simple aluminum chassis and external
connectors. It consists of two main boards:
•the encoder board
•modulator/RF board.
The encoder board handles all video input processing, digital pre-distortion, and
encoding. The FPGA, which in addition to the SDI block and digital pre-distortion, features
an embedded processor used for local encoder processing. The encoder is an H.264 HD
encoder.

The IQ Modulator/RF board generates the carrier frequency, modulates, and amplifies the
signal. The detected output from the amplifier is looped back for the ALC circuitry. It also
carries both the Wi-Fi and 900 MHz transceivers with an embedded ARM Processor for
the transmitters’ main controller.
