1.2 RF ENERGY EXPOSURE AWARENESS AND CONTROL
INFORMATION FOR FCC OCCUPATIONAL USE REQUIREMENTS
Before using the mobile two-way radio, read this important RF energy awareness and control
information and operational instructions to ensure compliance with RF exposure guidelines.
This radio is intended for use in occupational/controlled conditions, where users have
full knowledge of their exposure and can exercise control over their exposure to remain
NOTE
CAUTION
This two-way radio uses electromagnetic energy in the radio frequency (RF) spectrum to provide
communications between two or more users over a distance. It uses RF energy or radio waves to send and
receive calls. RF energy is one form of electromagnetic energy. Other forms include, but are not limited
to, electric power, sunlight, and x-rays. RF energy, however, should not be confused with these other
forms of electromagnetic energy, which, when used improperly, can cause biological damage. Very high
levels of x-rays, for example, can damage tissues and genetic material.
Experts in science, engineering, medicine, health, and industry work with organizations to develop
standards for exposure to RF energy. These standards provide recommended levels of RF exposure for
both workers and the general public. These recommended RF exposure levels include substantial margins
of protection. All two-way radios marketed in North America are designed, manufactured, and tested to
ensure they meet government-established RF exposure levels. In addition, manufacturers also recommend
below RF exposure limits. This radio is NOT authorized for general population,
consumer, or any other use.
Changes or modifications not expressly approved by M/A-COM, Inc. could void the
user's authority to operate the equipment.

MM-007024-001
specific operating instructions to users of two-way radios. These instructions are important because they
inform users about RF energy exposure and provide simple procedures on how to control it. Please refer
to the following websites for more information on what RF energy exposure is and how to control your
exposure to assure compliance with established RF exposure limits:
http://www.fcc.gov/oet/rfsafety/rf-faqs.html
http://www.osha.gov./SLTC/radiofrequencyradiation/index.html
1.2.1 Federal Communications Commission Regulations
The M7200 two-way mobile radio is designed and tested to comply with the FCC RF energy exposure
limits for mobile two-way radios before it can be marketed in the United States. When two-way radios are
used as a consequence of employment, the FCC requires users to be fully aware of and able to control
their exposure to meet occupational requirements. Exposure awareness can be facilitated by the use of a
label directing users to specific user awareness information. The radio has an RF exposure product label.
Also, this Installation Manual and the applicable Operator’s Manual include information and operating
instructions required to control your RF exposure and to satisfy compliance requirements.
1.3 COMPLIANCE WITH RF EXPOSURE STANDARDS
The M7200 two-way mobile radio is designed and tested to comply with a number of national and
international standards and guidelines regarding human exposure to RF electromagnetic energy. This
radio complies with the IEEE and ICNIRP exposure limits for occupational/controlled RF exposure
environment at duty-cycle times of up to 50% (50% transmit, 50% receive), and it is authorized by the
FCC for occupational use. In terms of measuring RF energy for compliance with the FCC exposure
guidelines, the radio’s antenna radiates measurable RF energy only while it is transmitting (talking), not
when it is receiving (listening) or in standby mode.
The M7200 mobile two-way radio complies with the following RF energy exposure standards and
guidelines:
• United States Federal Communications Commission (FCC), Code of Federal Regulations; 47 CFR
§ 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.
Table 1-1 lists the recommended minimum safe lateral distances for a controlled
environment and for unaware bystanders in an uncontrolled environment, from
transmitting antennas (i.e., monopoles over a ground plane, or dipoles) at rated radio
power for mobile radios installed in a vehicle. Transmit only when unaware bystanders
CAUTION
are at least the uncontrolled recommended minimum safe lateral distance away from
the transmitting antenna.

MM-007024-001
1.5 COMMON HAZARDS
The operator of any mobile radio should be aware of certain hazards common to the operation of
vehicular radio transmissions. Possible hazards include but are not limited to:
1. Explosive Atmospheres
Just as it is dangerous to fuel a vehicle with its motor running, be sure to turn the radio OFF while fueling
the vehicle. If the radio is mounted in the trunk of the vehicle, DO NOT carry containers of fuel in the
trunk.
2. Interference To Vehicular Electronic Systems
Electronic fuel injection systems, electronic anti-skid braking systems, electronic cruise control systems,
etc., are typical of the types of electronic devices that can malfunction due to the lack of protection from
radio frequency (RF) energy present when transmitting. If the vehicle contains such equipment, consult
the dealer for the make of vehicle and enlist his aid in determining if such electronic circuits perform
normally when the radio is transmitting.
3. Electric Blasting Caps
To prevent accidental detonation of electric blasting caps, DO NOT use two-way radio within 1000 feet
(305 meters) of blasting operations. Always obey the “Turn Off Two-Way Radios” signs posted where
electric blasting caps are being used. (OSHA Standard: 1926.900)
4. Radio Frequency Energy
To prevent burns or related physical injury from radio frequency energy, do not operate the transmitter
when anyone outside of the vehicle is within the minimum safe distance from the antenna as specified in
Table 1-1.
5. Vehicles Powered By Liquefied Petroleum (LP) Gas
Radio installation in vehicles powered by liquefied petroleum gas, where the LP gas container is located
in the trunk or other sealed-off space within the interior of the vehicle, must conform to the National Fire
Protection Association Standard NFPA 58. This requires:
a. The space containing radio equipment is isolated by a seal from the space containing the LP gas
container and its fittings.
b. Outside filling connections are used for the LP gas container.
c. The LP gas container space is vented to the outside of the vehicle.
6. Vehicles Equipped With Airbags
For driver and passenger safety, avoid mounting the Control Head (or any other component) above or
near airbag deployment areas. In addition to driver-side and passenger-side front-impact airbags, some
vehicles may also be equipped with side-impact airbags. For occupant safety, verify the location of all
airbags within the vehicle before installing the radio equipment.

3 INTRODUCTION
3.1 GENERAL DESCRIPTION
The M7200 series mobile radios are high-performance full-duplex dual-band digital mobile radios. These
radios can operate on 700 MHz and 800 MHz OpenSky trunked radio networks using the OpenSky
Trunking Protocol (OTP). In the future, the radio will also operate on 800 MHz Enhanced Digital Access
Communications System (EDACS) trunked radio networks, and 800 MHz APCO Project 25 phase I
compliant Common Air Interface (P25 CAI) trunked radio networks. Other future operating modes
include talk-around communications in accordance the APCO Project 25 phase I standard, and
conventional FM repeater-based and FM talk-around voice communications in accordance with the
TIA/EIA-603 conventional land-mobile radio standard.
The initial release of this radio only supports operations on 700 MHz and 800 MHz
OpenSky trunked radio networks. Later releases of the radio will add other modes to
NOTE
support other trunked radio networks, and conventional FM repeater-based and FM
talk-around voice communication modes.
The radio has two models:
• M7250 — Trunk-Mount Full-Duplex Mobile Radio with CH-103 or CH-103PA Control Head
MM-007024-001
• M7270 — Trunk-Mount Full-Duplex Mobile Radio with CH-721 Control Head. As of the
publication of this manual, this combination is not available.
This manual only covers the installation of the M7250 model mobile radio.
The M7250 model mobile radio is designed to operate in a mobile environment, typically within a motor
vehicle. It must be connected to an external transmit/receive antenna such as one mounted to the vehicle’s
rooftop or trunk lid. In high-power half-duplex mode, the radio’s 800 MHz RF transmit output power is
rated at 15 watts minimum. The high-power limit for 700 MHz interoperability channels operations is
300 milliwatts maximum. This high-power limit guarantees that the 2-watt ERP (effective radiated
power) limit of the 700 MHz interoperability narrowband channels is not exceeded when the radio is
connected to a 6 dB gain antenna. Several different types of external-mount antennas are approved and
available for use with the radio, as listed in Table 1-1 and Table 4-2.
The radio is designed for remote mounting in a motor vehicle’s trunk, or some other preferably
unoccupied section in a vehicle, such as a fire truck’s equipment shelf. It is remotely controlled by one or
more control heads connected to it via a 3-wire Controller Area Network (CAN) link cable. Between the
radio and control head(s), the CAN link carries digitized microphone and speaker audio, controlling data
such as button presses and radio messages, and user data such as that for a mobile data terminal connected
to serial port of the radio or control head. For proper operation, the CAN link must be terminated
appropriately on each end.
Control heads which may be utilized with the radio include the standard CH-103 and the siren/public
address CH-103PA control head. The CH-103PA can interface to an optional Federal Signal Electronic
siren/light control system for broadcasting via a public address (PA) speaker. In multiple control head
installations, control heads are interconnected to the mobile radio in a series (daisy-chain) fashion via
CAN link cables. Other control head models are planned in the future.
The radio must be powered by an external +13.6-volt (nominal) DC power source. In mobile applications,
the motor vehicle’s electrical system is the source of DC power. The control head(s) connected to the
radio is also powered by the same DC power source, but separately fused. When the control head is
powered-up by the operator, it “wakes up” the radio by transmitting data to the radio via the CAN link.
11
MM-007024-001
The radio provides half-duplex voice communications, and both half- and full-duplex data
communications. Voice communication is accomplished via a “push-to-talk” (PTT) type microphone and
a speaker connected to the mobile radio’s control head.
For data communications, the radio has an industry-standard TIA/EIA/RS-232 serial interface port for
connecting optional data-type equipment, such a Mobile Data Terminal (MDT), a laptop PC, a third-party
display, or a key-entry device. This port works seamlessly with equipment from popular manufacturers
and off-the-shelf applications. OpenSky employs User Datagram Protocol over Internet Protocol
(UDP/IP) data packet transfers, providing “plug and play” connectivity for data-type devices.
700 MHz operating bands of the radio include the two 3 MHz wide repeater output bands from 764 to
767 MHz and 773 to 776 MHz, and the two 3 MHz wide repeater input bands from 794 to 797 MHz and
803 to 806 MHz. The mobile can operate only on the narrowband channels within these bands and, as
previously stated, transmit output power is limited to 300 milliwatts.
800 MHz operating bands of the radio include the Specialized Mobile Radio (SMR) and the National
Public Safety Planning Advisory Committee (NPSPAC) radio frequency channels. This includes the 806
to 825 MHz repeater input band and the 851 to 870 MHz band used for repeater output and talk-around
communications. These bands provide a total of over 830 possible channels spread over the
806 - 824 MHz mobile transmission and 851 - 869 MHz mobile reception bands.
The radio has a built-in Global Positioning System (GPS) tracking receiver. GPS provides quick and
accurate unit location information to dispatchers via the radio network. The GPS receiver determines the
unit’s location and the radio transmits it to the radio network. The GPS antenna may be integrated into the
mobile transmit/receive antenna (a “combination” antenna) or it may be separate from the mobile
transmit/receive antenna.
The radio meets or exceeds many tough environmental specifications included within military standard
MIL-STD-810F, automotive industry standard SAE-J1455, the radio industry standard TIA/EIA-603, and
the radio standard established by the U.S. Forest Service.
OpenSky employs Adaptive Multi-Band Excitation (AMBE™) voice-coding technology developed by
Digital Voice Systems, Inc. AMBE allows the radio to deliver exceptional voice quality, even in weak
received signal areas (i.e., “fringe” areas).
OpenSky radio network also uses Time-Division Multiple-Access (TDMA) modulation technology. This
technology allows multiple radio users to share a single RF channel. In addition, a single RF channel can
support simultaneous digital voice and data communications.
This manual contains installation procedures for the mobile radio, and the CH-103 and CH-103PA control
heads. These procedures cover the mounting and cabling of the equipment as well as the testing of the
radio and control head. Interconnect wiring diagrams are included at the rear of this manual.

5.3 LOCATING COMPONENTS
Plan the mounting locations of all components (radio, control head, antenna, and cables) and determine
the routes for all wiring and cables. Particularly consider the connection of the control head for planning
purposes.
• Determine the customer’s preferences, if any, for location of components. Comply with these
preferences as long as they are consistent with safety recommendations and guidelines presented in
this manual, and other generally accepted professional radio installation practices.
• Nominal dimensions for the radio are 2.8 x 8.8 x 9.3 inches (7.1 x 22.4 x 23.6 centimeters; height x
width x depth). This includes the base bracket and its mounting tabs, but it does not include any
clearance space required for cabling, air circulation, access to mounting hardware, etc.
• Verify sufficient clearance behind the units is provided so cables will not be stressed, crushed,
twisted, or bent at severe angles. Also, the front and sides must have clearance for air circulation,
access to mounting hardware, etc.
• Connections on the radio are made through “pigtail” type cables exiting the rear of the radio. This
design minimizes the stresses associated with mating connections and it allows for easy connector
mating. However, stresses can still be induced if adequate service looping is not employed.
Connections to the CH-103 and CH-103PA Control Heads are made with connectors mounted on the
rear panel of each head instead of “pigtail” type cables.
CAUTION
All cables should have a service loop near each connector end. Do not bend the cables
at severe angles near the connector end. Above all, after all components are installed,
verify no cable is under any tension. Failure to do so may lead to damaged cables,
causing intermittent radio operation or complete radio failure.
