1-3. 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 Motorola 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 50% talk-50% 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 Motorola 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.
1-3.1 Compliance and Control Guidelines and Operating Instructions for
Mobile Two-Way Radios Installed in Vehicles
To control your exposure and ensure compliance with the occupational/ controlled environment
exposure limits, always adhere to the following procedures:
• To transmit (talk), push the Push-To-Talk (PTT) button; to receive, release the PTT button.
Transmit only when people outside the vehicle are at least the minimum lateral distance
away (as shown in table below) from a properly installed, externally-mounted antenna.
The table below lists the minimum lateral distance for bystanders in an uncontrolled environment
from the transmitting antenna at several different ranges of rated radio power for mobile radios
installed in a vehicle.

• Install mobile antennas at the center of the roof or the center of the trunk deck per specific
guidelines and instructions in the Radio Installation Manual. These mobile antenna
installation guidelines are limited to metal body vehicles.
Use only the Motorola-approved, supplied antenna or a Motorola- approved replacement
antenna. Use of non-Motorola-approved antennas, modifications, or attachments could damage
the radio and may violate FCC regulations.

1-3.2 Compliance and Control Guidelines and Operating Instructions for
Mobile Two-Way Radios Installed as Fixed Site Control Stations
If mobile radio equipment is installed at a fixed location and operated as a control station or as a
fixed unit, the antenna installation must comply with the following requirements in order to ensure
optimal performance and compliance with the RF energy exposure limits in the standards and
guidelines listed in the Federal Communication Commission Regulations section.
• The antenna should be mounted outside the building on the roof or a tower if at all possible.
• As with all fixed site antenna installations, it is the responsibility of the licensee to manage the site
in accordance with applicable regulatory requirements and may require additional compliance
actions such as site survey measurements, signage, and site access restrictions in order to ensure
that exposure limits are not exceeded.
1-3.3 Electromagnetic Interference/Compatibility
Note
Nearly every electronic device is susceptible to electromagnetic interference (EMI)
if inadequately shielded, designed, or otherwise configured for electromagnetic
compatibility. It may be necessary to conduct compatibility testing to determine if
any electronic equipment used in or around vehicles or near fixed site antenna is
sensitive to external RF energy or if any procedures need to be followed to
eliminate or mitigate the potential for interaction between the radio transmitter
and the equipment or device.
Cat. No. 6886859J01
1-3
1-3.4 Facilities
To avoid electromagnetic interference and/or compatibility conflicts, turn off your radio In any
facility where posted notices instruct you to do so. Hospitals or health care facilities may be using
equipment that is sensitive to external RF energy.
1-3.5 Vehicles
To avoid possible interaction between the radio transmitter and any vehicle electronic control
modules, for example, ABS, engine, or transmission controls, the radio should be installed only by an
experienced installer and that the following precautions be used when installing the radio:
1. Refer to the manufacturer's instructions or other technical bulletins for recommendations on
radio installation.
2. Before installing the radio, determine the location of the electronic control modules and their
harnesses in the vehicle.
3. Route all radio wiring, including the antenna transmission line, as far away as possible from the
electronic control units and associated wiring.
1-3.6 Driver Safety
Check the laws and regulations on the use of radios in the area where you drive. Always obey them.
1-3.7 When using your radio while driving, please:
• Give full attention to driving and to the road.
• Pull off the road and park before making or answering a call if driving conditions so require.
1-3.8 Operational Warnings
For Vehicles with an Air Bag
Do not mount or place a mobile radio in the area over an air bag
Warning
deployment area. Air bags inflate with great force. If a radio Is placed in
the air bag deployment area and the air bag inflates, the radio may be
propelled with great force and cause serious injury to occupants of the
vehicle.
Potentially Explosive Atmospheres
Turn off your radio prior to entering any area with a potentially explosive
atmosphere. Sparks in a potentially explosive atmosphere can cause an
explosion or fire resulting in bodily injury or even death.
1-4
The areas with potentially explosive atmospheres include fueling areas
such as below decks on boats, fuel or chemical transfer or storage
facilities, and areas where the air contains chemicals or particles such as
grain, dust or metal powders. Areas with potentially explosive
atmospheres are often, but not always, posted.
Cat. No. 6886859J01
Blasting Caps and Blasting Areas
To avoid possible interference with blasting operations, turn off warning
Warning
your radio when you are near electrical blasting caps, in a blasting area,
or in areas posted: "Turn off two-way radio". Obey all signs and
instructions.
For radios installed in vehicles fueled by liquefied petroleum gas, refer to
the (U.S.) National Fire Protection Association standard, NFPA 58, for
storage, handling, and/or container information. For a copy of the LP-gas
standard, NFPA 58, contact the National Fire Protection Association, One
Battery Park, Quincy, MA.
1-3.9 Restrictions
Because this radio contains a transmitter, federal law prohibits unauthorized, non-licensed personnel
from adjusting or maintaining it. If any operational difficulties should arise while using this product,
report them to authorized service personnel as soon as possible.
Do not attempt any unauthorized modification to the radio.
Warning
1-4. Safe Handling of CMOS Devices
Complementary metal-oxide semiconductor (CMOS) devices are used in this family of radios. While
the attributes of CMOS are many, their characteristics make them susceptible to damage by
electrostatic or high voltage charges. Damage can be latent, resulting in failures occurring weeks or
months later. Therefore, special precautions must be taken to prevent device damage during
disassembly, troubleshooting, and repair. Handling precautions are mandatory for CMOS circuits and
are especially important in low humidity conditions.
Caution
1. Eliminate static generators (plastics, styrofoam, etc.) in the work area.
2. Remove nylon or double-knit polyester jackets, roll up long sleeves, and remove or tie back
loose hanging neckties.
3. Store and transport all static-sensitive devices in ESD protective containers.
4. If at all possible, handle CMOS devices by the package and not by the leads. Prior to touching
the unit, touch an electrical ground to remove any static charge that you may have
accumulated. The package and substrate may be electrically common. If so, the reaction of a
discharge to the case would cause the same damage as touching the leads.
5. Disconnect all power from the unit before ESD sensitive components are removed or inserted,
unless otherwise noted.
Do not attempt to disassemble the radio without observing the following
handling precautions.
Cat. No. 6886859J01
1-5
6. Use a static safeguarded workstation, which can be accomplished through the use of an antistatic kit (for example, Motorola part number 0180386A82). This kit includes a wrist strap,
two ground cords, a static-control table mat and a static-control floor mat.
When these items are not readily available, observing the following techniques will minimize
chance of damage:
• If a static-sensitive device is to be temporarily set down, use a conductive surface for
placement of the device.
• Make skin contact with a conductive work surface first and maintain this contact when
the device is set down or picked up.
7. Always wear a conductive strap when servicing this equipment. The Motorola part number for
a replacement wrist strap that connects to the table mat is 42-80385A58.
8. When straightening CMOS pins, provide ground straps for apparatus used.
9. When soldering, use a grounded soldering iron.
