SAFETY INFORMATION
Product Safety and RF Exposure for Mobile Two-Way Radios Installed in
Vehicles or as Fixed Site Control Stations
The information provided in this document supersedes the general safety information contained in
user guides published prior to February 2002.
RF Energy Exposure Awareness and Control Information, and
Operational Instructions for FCC Occupational Use Requirements
NOTICE: 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 meet FCC limits. This radio device is NOT authorized for general population,
consumer or any other use.
This 2-way radio uses electromagnetic energy in the radio frequency (RF) spectrum to provide
communications between two or more users over a distance. It uses radio frequency (RF) energy or
radio waves to send and receive calls. RF energy is one from of electromagnetic energy. Other
forms include, but are not limited to, 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 safe 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 Motorola 2-way radios are designed, manufactured, and tested to ensure they meet government-
established RF exposure levels. In addition, manufacturers also recommend specific operating
instructions to users of 2-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 Web sites for more information on what RF energy exposure is and how
to control your exposure to assure compliance with established RF exposure limits.

BEFORE USING THIS RADIO, READ THIS BOOKLET WHICH CONTAINS IMPORTANT OPERAT-
ING INSTRUCTIONS FOR SAFE USAGE AND RF ENERGY AWARENESS AND CONTROL
INFORMATION FOR COMPLIANCE WITH RF ENERGY EXPOSURE LIMITS IN APPLICABLE
NATIONAL AND INTERNATIONAL STANDARDS.
