RF ENERGY EXPOSURE AND PRODUCT SAFETY GUIDE
WARNINGS
Before using this radio, read this guide which
contains important operating instructions for
safe usage and RF energy awareness and
control for compliance with applicable
standards and regulations.
This radio uses electromagnetic energy in the radio
frequency (RF) spectrum to provide communications be-
tween two or more users over a distance. RF energy,
which when used improperly, can cause biological damage.
All Retekess radios are designed, manufactured, and
tested to ensure they meet government-established RF
exposure levels. In addition, manufacturers also recom-
mend specific operating instructions to users of the 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
