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
Warnings
RF ENERGY EXPOSURE AND PRODUCT SAFETY GUIDE
FOR PORTABLE WALKIE TALKIE
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/
ATTENTION!
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.
