1 Preface
Congratulations on purchasing a Thales Affinity® Transmitter. We would like to welcome you to
the future of digital broadcasting and especially to the Thales Broadcast & Multimedia family.
Your Affinity® is a state-of-the-art low power digital L-Band transmitter. In addition to the
sophisticated on-board diagnostic test and measurement features, major assemblies within the
Affinity® are housed in a convenient modular plug-in package. This modular design philosophy
allows for “Hot Swap” module replacement without the necessity of shutting down the entire
transmitter for long periods. The “Hot Swap” plug-in module feature virtually eliminates costly
downtime.
Before receiving your Affinity®, the transmitter was subjected to a battery of quality assurance
inspections and functional tests to assure years of dependable and reliable on-air broadcasting.
In addition to ensuring that the appropriate support materials are supplied with the transmitter, it
should be comforting to know that Thales Customer Service representatives are only a click
http://csg.us.thales-bm.com or phone call (800-345-9295) away. Check out the volumes of
Thales product support literature, service bulletins, and other related information on our service
web site, and be sure to visit us at our upcoming trade-shows and forums.
Again, thanks for choosing Thales Broadcast & Multimedia as your digital broadcasting partner.

Product Manual
2 Introduction
The intention of this Affinity® Product Manual is to familiarize an operator with the setup, basic
operation, and functions of the Thales Affinity® LBD-200C-N1 L-Band Transmitter.
Non-technical personnel should avoid performing any operations and/or procedures contained
within this manual without obtaining the proper training. Semi-technical personnel may perform
the operations and/or procedures appropriate to their skill-level and training.
It is highly recommended that the normal operation, maintenance, and servicing of this
transmitter be performed only by qualified and trained technicians or personnel.
CAUTION: Observe caution while at the transmitter site or while engaged in any transmitter
maintenance. Refer to the Safety section of this manual for additional information on the
dangers and hazardous conditions that are present in and around the transmitter site, and on
the precautions the operator must observe while working within the transmitter area.

3 Safety Information
3.1 Introduction
The Thales Broadcast & Multimedia Affinity® transmitter conforms to the safety information
contained in the International Electrotechnical Commission (IEC) publication 60215 (1987-06)
(www.iec.ch). The design and manufacturing approach of the transmitter will protect the
operator from dangerous voltages, heat, radiation, and other hazards if operated within the
confines of the specification. Thales has attached warning labels to the enclosures and/or
various assemblies to identify potentially dangerous conditions to the operator. Operators must
adhere to these warning labels.
Thales recommends that only skilled personnel, as defined by the IEC 60215 publication, be
permitted to operate the transmitter. Proper training and correct equipment operation will
remove the risk of hazardous conditions and dangers to the operator.
3.2 Warnings, Cautions, and Notes
This manual contains WARNING and CAUTION notices that identify procedures, conditions,
and materials that could potentially cause death, injury, or damage to equipment.
AWARNING notice will appear before a procedure or instruction if injury or death could result
from performing the procedure or instruction incorrectly.
ACAUTION notice will appear before a procedure or instruction if equipment damage could
occur from performing the procedure or instruction incorrectly.
ANOTE appears after a paragraph to highlight important information.
WARNING
This equipment uses dangerous voltages that
can cause injury or death. Observe applicable
safety precautions.
CAUTION
Do not operate the transmitter with the antenna
and station-load disconnected. Doing so may
damage the transmitter.
Warning and Caution Samples
NOTE: The RF Sample contains pre-distortion and is not representative of output signal. The
RF sample is a reference point for testing only.

3.3 Safety Symbols
Assemblies within the transmitter system that contain high voltage conditions have safety
symbols attached to them.
HIGH VOLTAGE
This symbol identifies the presence of high voltage that can cause injury or death.
3.4 Electrical Shock and the Human Body
Electrical shock or electrocution occurs when the body becomes part of an energized electrical
path and this electrical energy passes through the body.
The body subjected to a difference of potential, or stored electrical charge causing current to
flow through the body, will be shocked or electrocuted. Effects of electrical shock may include
severe burns to the skin and/or internal organs and respiratory or cardiac arrest. Any electrical
current that flows through the central nervous system of the human body has the potential to
cause serious injury or death.
Severity of electrical shock depends upon the source and duration of exposure. Use the
following information in conjunction with a vigilant and on-going safety program. This information
is in general terms and does not include unknown variables that may increase susceptibility to
electrical shock. Always exercise Awareness and Caution.
Direct Current (DC): Low voltage (up to 72 VDC) usually does not present a hazard to human
life, but a severe burn is possible under some conditions. Medium and high voltage (greater
than 72 VDC) can cause severe shocks, burns, and even death.
Alternating Current (AC): At commercial frequencies (50-60 Hz) and intermediate voltages (72
to 600 VAC), lethal current can flow through the body. Even low AC voltages (24 VAC or less)
under certain circumstances can be dangerous and lethal. The danger of shock is less at high
frequencies, but radio-frequency (RF) burns are possible.
Body Resistance: The resistance of the body and the amount of insulation between the body
and electrical earth-ground determine the amount of electrical current that passes through the
body. The skin presents the greatest resistance of the human body to impede current flow.
Please note that skin resistance decreases with increased voltage.
Time of Contact: The length of time the body remains in contact with electrical current
determines the severity of possible injury. Burns break down the skin and thus lowers the body’s
ability to resist electrical current. The more extensive the burn, the less resistance the skin
provides. As current flow increases, so does the severity of the shock. The duration of contact is
critical. Current flowing through the body causes loss of muscle control, chest contractions
(breathing is impaired) and ventricular fibrillation of the heart. During fibrillation, the heart cannot
pump sufficient quantities of blood.
Magnitude: The magnitude of the electrical current determines the extent of muscle-control
loss, effects on the heart, and severity of burns.
