FEDERAL COMMUNICATION COMMISSION REGULATIONS
The FCC has established limits for safe exposure to radio frequency (RF) emissions from mobile
two-way radios. The FCC requires manufacturers to demonstrate compliance with RF exposure limits
before mobile two-way radios can be marketed in the U.S. When two-way radios are approved for
occupational/controlled environment exposure limits, the FCC requires users to be fully aware of, and
exercise control over, their exposure. Awareness and control of RF exposure can be accomplished by
education or training through appropriate means such as information and instructions in user manuals
or safety booklets, or other appropriate means. This user safety booklet includes useful information
about RF exposure and helpful instructions on how to control your RF exposure.
Your two-way radio is designed and tested to comply with a number of national and international
standards and guidelines (listed below) regarding human exposure to radio frequency electromagnetic
energy. This radio complies with the IEEE (FCC) and ICNIRP exposure limits for
occupational/controlled RF exposure environments at usage factors of up to 10% talk-90% listen. In
terms of measuring RF energy for compliance with FCC exposure guidelines, your radio radiates
measurable RF energy only while it is transmitting (during talking), not when it is receiving (listening) or
in standby mode.
Your two-way radio complies with the following RF energy exposure standards and guidelines:
• United States Federal Communications Commission, Code of Federal Regulations; 47CFR part
2 sub-part J
• American National Standards Institute (ANSI)/Institute of Electrical and Electronic Engineers
(IEEE) C95.1-1992
• Institute of Electrical and Electronic Engineers (IEEE) C95.1-1999 Edition
• International Commission on Non-Ionizing Radiation Protection (ICNIRP) 1998
• Ministry of Health (Canada) Safety Code 6: Limits of Human Exposure to Radiofrequency
Electromagnetic Fields in the Frequency Range from 3 kHz to 300 GHz, 1999
• Australian Communications Authority Radiocommunications (Electromagnetic Radiation –
Human Exposure) Standard, 2001
• ANATEL, Brasil Regulatory Authority, Resolution 256 (April 11, 2001). Additional Requirements
for SMR, Cellular and PCS Product Certification.
SAFETY SUMMARY
The following are general safety precautions that are not related to any specific procedures and
therefore do not appear elsewhere in this publication. These are recommended precautions that
personnel must understand and apply during various phases of operation and maintenance.
KEEP AWAY FROM LIVE CIRCUITS. Operating personnel must at all times observe all safety
regulations. Do not replace components or make adjustments inside the equipment with the high
voltage supply turned on. Under certain conditions, dangerous potentials may exist even when the
power control is in the OFF position, due to charges retained by capacitors. To avoid casualties,
always remove power and discharge and ground a circuit before touching it.
DO NOT SERVICE OR ADJUST ALONE. Under no circumstances should any person reach into the
equipment enclosure for the purpose of servicing or adjusting the equipment except in the presence of
someone who is capable of rendering aid.
RESUSCITATION. Personnel working with or near high voltages should be familiar with modern
methods of resuscitation.
USE SAFETY APPROVED EQUIPMENT. When cleaners and primers are being applied, approved
explosion-proof lights, blowers, and other equipment shall be used. Insure that firefighting equipment is
readily available and in working order.
GIVE CLEANERS SPECIAL CARE. Keep cleaners in special polyethylene bottles or in safety cans
and in minimum quantities. Discard soiled cleaning cloths into safety cans.

OM-E 2072-09287-00
The Micom Pathfinder capabilities provide reliable long-range HF-SSB radio communications in a
rugged yet lightweight manpack configuration. Designed to meet the needs of users who carry out
on-foot operations in remote areas, it is built to withstand years of shock and vibration as well as
severe weather conditions. Micom Pathfinder is certified for dependability and durability, and
complies with the applicable sections of MIL-STD-810F and MIL-STD-810E.
Micom Pathfinder supports voice and data communications. Micom Pathfinder supports data rates up
to 4800 bps by means of an optional internal (embedded) modem.
Extensive use of digital signal processing (DSP) ensures high performance; a built-in voice quality
system with proprietary DSP algorithms filter out background noise and elevates sound bytes
providing exceptional communication clarity and voice quality. Many advanced features are standard,
such as digital noise blanking and voice-activated digital squelch. Optional features such as embedded
data modem, embedded vocoder, embedded AES encryption, etc., are also available. Moreover, the
addition of new features and upgrading to future technologies are easily made by software updating.
To ensure the best possible communication reliability, Micom Pathfinder Automatic Link
Establishment (ALE) has been certified by the Joint Interoperability Test Center (JITC) to MIL-STD188-141B. In addition, the ALE function also provides Automatic Message Display (AMD), that
enables operators to exchange preprogrammed messages while establishing a link. The AMD function
is also used in several advanced optional features, such as automatic position reporting (either
operator-initiated or in response to queries) when a GPS receiver is installed, and automatic adoption
of the encryption key used by the transmitting station (provided the necessary key is available at the
receiving station).

1-3.2 Micom Receiver/Transmitter
The Micom Pathfinder receiver/transmitter unit performs the following main functions:
• Generates the transmit signals.
• Demodulates the received signals.
• Processes the GPS signals (optional).
• Provides the interfaces to the operator, and to data equipment using Micom Pathfinder for radio
communications.
Figure 1-2 shows a general view of Micom Pathfinder, including its battery box.
Figure 1-2. Micom Pathfinder
Receiver/Transmitter
The Micom Pathfinder is a complete HF/SSB receiver-transmitter, powered by a 14.4 V Lithium-Ion
battery installed in a battery box attached to the rear side by two clamps. The box houses the battery
and protects the battery against environmental elements.
The nominal output impedance of the Micom Pathfinder is 50 Ω, and therefore it can be directly
connected to broadband antennas (dipoles, traveling wave antennas, delta and semi-delta antennas).
An internal antenna tuner enables using various whip antennas (in addition to the 2.7 meter (9 ft)
antenna offered as a standard for the Micom Pathfinder). The transmitter includes antenna mismatch
protection: if the VSWR (Voltage Standing Wave Ratio) is too high, for example, because the antenna
is disconnected or damaged, the transmission will be inhibited to avoid damage, and a message will be
displayed. In addition, if for any reason, the transmitter internal temperature exceeds the maximum
permitted temperature, the transmitter output power is automatically reduced to avoid fault due to
excessive heat.
1-3
OM-E 2072-09287-00
The Micom Pathfinder has an intelligent, user-friendly man-machine interface that enables easy
operation. The display provides feedback to the operator and shows extensive information concerning
system status (e.g., mode of operation, link status, call progress indications, low battery condition,
etc.), as well as the GPS data (when this option is used). Support for multiple languages is also
available.
1-3.3 Carrying Harness
Micom Pathfinder carrying harness consists of
a lightweight nylon harness with adjustable
shoulder straps that enable carrying all the
necessary accessories. Additional waist and
breast straps, also easily adjustable for best fit
and user’s comfort, stabilize the harness while
walking and running.
A foldable rear support enables placing the
harness on ground, vertically, for dismounted
operation.
CAUTION
During dismounted operation, use
the supplied grounding spike and
strap to ground the Micom
Pathfinder unit.
Figure 1-3. Micom Pathfinder Carrying Harness,
General View (Closed for Transport)
For best equipment protection, the carrying harness completely envelops the transceiver. A front flap
with zippers provides easy access to the internal storage compartments for cables and spare battery,
and also permits the installation of the transceiver. After installing the transceiver, the front flap
remains closed: a separate top flap can be opened to access the transceiver front panel, install the
antenna and the handset, and operate the radio set.
Side pouches can be used to carry the folded whip antenna, and other accessories. The optional GPS
antenna is attached to the side of the harness.
1-3.4 FAD5530 Collapsible 9-Foot Whip Antenna
The FAD5530 whip antenna is the standard Micom Pathfinder antenna used for short-range
ground-wave communication, and is suitable for portable operation. Antenna matching is performed
by the Micom internal automatic antenna tuner, and thus FAD5530 is directly connected to the WHIP
connector of the Micom.
The FAD5530 whip antenna consists of two components:
• AT-271A Collapsible Antenna. The antenna is composed of six sections. Each section fits into
the end of a wider section. A stainless-steel plastic-covered cable (or braided plastic cord),
under spring tension, is threaded through the sections to keep them together when operating.
When the sections are folded, the cable keeps them together as a group, to prevent the loss of
individual sections. Spring tension is provided by a spiral spring in the base section.
• AB-591 Antenna Base Adapter. The antenna base adapter serves as the main support for the
AT-271A.
A safety strap is supplied to fasten the antenna sections together, when the radio set is transported with
the antenna folded.

OM-E 2072-09287-00
1-3.5 FAA5548 (AT-1743) Portable Dipole Antenna
The optional FAA5548 dipole antenna, described in Appendix B, is a lightweight portable antenna for
the frequency range of 2 to 30 MHz. This antenna is recommended for use during static operation,
when long communication ranges are required: when using a properly selected operating frequency,
FAA5548 provides continuous coverage for communication ranges of up to 1,000 kilometers.
The FAA5548 antenna consists of two antenna wires, which are attached to an insulator (center unit).
The insulator is connected by means of the coaxial feed cable to the front-panel DIPOLE connector.
The length of the antenna wires is coarsely adjusted in accordance with the operating frequency. Two
cords are used to stretch the wires. The cords are fastened to nearby supports, e.g. trees, poles, etc.
When properly adjusted to the operating frequency range, the FAA5548 input impedance is close to
50 Ω, and therefore it is possible to connect FAA5548 directly to the DIPOLE connector of the Micom
Pathfinder. When the selected operation mode involves automatic changing of the operating
frequency, e.g., for ALE operation, the antenna should be adjusted to the average operation frequency.
1-3.6 GPS Antenna, AT-1000 (for Use with Option G421)
The GPS antenna, AT-1000, is a compact active omnidirectional antenna which connects to the GPS
connector of the Micom Pathfinder through a coaxial cable that carries both DC power and the
received GPS signals. The AT-1000 has a threaded stud on its base, which can be used to fasten the
antenna to an appropriate adapter. Figure 1-4 shows a general view of the antenna.
Figure 1-4. GPS Antenna, AT-1000
For use in Micom Pathfinder, the required adapter is AD-1000P, and the coaxial cable is CG-5602.
AD-1000P is used to attach the AT-1000 to the Micom Pathfinder carrying harness. Figure 1-5 shows
a general view of the antenna adapter.
