RF ENERGY EXPOSURE AND PRODUCT SAFETY GUIDE
This radio uses electromagnetic energy in the radio frequency (RF) spectrum to provide communic-
ations 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:

Local Government Regulations
When 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 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.

Radio License (if appropriate)
Governments keep the radios in classification, business radios operate on radio frequencies that
are regulated by the local radio management departments (FCC, ISED, OFCOM, ANFR, BFTK,
Bundes-netzagentur...).To transmit on these frequencies, you are required to have a license
issued by them.
The detailed classification and the use of your radios, please contact the local government
radio management departments.
Use of this radio outside the country where it was intended to be distributed is subject to
government regulations and may be prohibited.

2) this device must accept any interference received, including interference that may cause
undesired operation.
• This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation.
This equipment generates uses and can radiate radio frequency energy and, if not installed and
used in accordance with the instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular installation. If this
equipment does cause harmful interference to radio or television reception, which can be determ-
ined by turningthe equipment off and on, the user is encouraged to try to correct the interference
by one or more of the following measures:
- Reorient or relocate the receiving antenna.
