RF ENERGY EXPOSURE AND PRODUCT SAFETY GUIDE FOR PORTABLE
TWO-WAY RADIOS
This two-way radio uses electromagnetic energy in the radio frequency (RF) spectrum to provide communications
between two or more users over a distance. RF energy, which when used improperly, can cause biological damage.
All Retevis two-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 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.who.int/en/
Local Government Regulations
When two-way radios are used as a consequence of employment, the Local Government Regulations 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 product label directing users to specific user awareness information. Your Retevis
two-way radio has a RF Exposure Product Label. Also, your Retevis user manual, or separate safety booklet includes
information and operating instructions required to control your RF exposure and to satisfy compliance requirements.
Radio License
Governments keep the radios in classification, business two-way radios operate on radio frequencies that are

RF ENERGY EXPOSURE AND PRODUCT SAFETY GUIDE FOR PORTABLE
TWO-WAY RADIOS
This two-way radio uses electromagnetic energy in the radio frequency (RF) spectrum to provide communications
between two or more users over a distance. RF energy, which when used improperly, can cause biological damage.
All Retevis two-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 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.who.int/en/
Local Government Regulations
When two-way radios are used as a consequence of employment, the Local Government Regulations 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 product label directing users to specific user awareness information. Your Retevis
two-way radio has a RF Exposure Product Label. Also, your Retevis user manual, or separate safety booklet includes
information and operating instructions required to control your RF exposure and to satisfy compliance requirements.
