Warnings
This radio uses electromagnetic energy in the radio frequency (RF) spectrum to provide commu-
nications between 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
recommend 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
When radios are used as a consequence of employment, the Local Government Regulations req-
uires users to be fully aware of and able to control their exposure to meet occupational require-
ments. Exposure awareness can be facilitated by the use of a product label directing users to
specific user awareness information. Your Retekess radio has a RF Exposure Product Label.
Also, your Retekess user manual, or separate safety booklet includes information and operating
instructions required to control your RF exposure and to satisfy compliance requirements.
