RF ENERGY EXPOSURE AND PRODUCT SAFETY GUIDE
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 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:
http://www.who.int/en/
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.
Solution
Re-insert
Plug to the power jack

and substation
Keep further distance between the
master station and the substation
Adjust the volume of master station
and substation lower
Adjust the volume of master station
higher by clockwise
Keep the closer distance
Please re-calibration
Adjust the volume of substation
higher by clockwise
Keep the closer distance

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
