SAFETY INFORMATION
Read this information before using your radio.
PRODUCT SAFETY AND RF EXPOSURE FOR MOBILE TWO-WAY RADIOS 
INSTALLED IN VEHICLES OR AS FIXED SITE CONTROL STATIONS.
This document provides information and instructions for the safe and efficient operation of Motorola 
Mobile Two-Way Radios.
 The information provided in this document supersedes information 
contained in user guides published prior to February 2002.
COMPLIANCE WITH RF ENERGY EXPOSURE STANDARDS
Note:This Radio is intended for use in occupational/controlled applications, where users have been 
made aware of the potential for exposure and can exercise control over their exposure. This radio 
device is NOT authorized for general population, consumer or similar use.
This user safety booklet includes useful information about RF exposure and helpful instructions on 
how to control your RF exposures.
Your Motorola radio is designed and tested to comply with a number of national and international 
standards and guidelines regarding human exposure to radio frequency electromagnetic energy. This 
radio complies with IEEE 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 the IEEE/ICNIRP 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; 47 CFR 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 Electro-
magnetic 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.” 
						

							vi
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 from a properly 
installed, externally-mounted antenna. Table 1 lists the minimum 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 centre of the roof and centre of the trunk deck. These mobile installa-
tion guidelines are limited to metal body vehicles. The antenna installation must additionally be in 
accordance with: 
a. The requirements of the antenna manufacturer/supplier
b. Instructions in the Radio Installation Manual.
●Use only Motorola-approved supplied or replacement antenna. Use of non–Motorola - approved 
antennas, modifications, or attachments could damage the radio and may violate 
IEEE/ICNIRP regu-
lations. For a list of Motorola-approved antennas please see your dealer. Your nearest dealer can 
be found at the following web site :
http://www.motorola.com/cgiss/emea/dealerlocator.html
For additional information on exposure requirements or other training information, visit

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 in the standards and guidelines listed 
above:
●The antenna must 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 insure that 
exposure limits are not exceeded. Ta b l e  1 :  Rated Power and Distance

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.
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.
Ve hicles
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 or 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.
Driver Safety
Check the laws and regulations on the use of radios in the area where you drive. Always obey them.
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. 
OPERATIONAL WARNINGS
For Vehicles With An Air Bag
Do not mount or place a mobile radio in the area over an air bag or in the air bag 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.
The areas with potentially explosive atmospheres referred to above include fuelling areas such as 
below decks on boats, fuel or chemical transfer or storage facilities, 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.
Blasting Caps And Areas
To avoid possible interference with blasting operations, turn off 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. 
						

							viii
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.
