Before using this radio, read this guide which cont-
ains important operating instructions for safe usage
and RF energy awareness and control for compliance
with applicable standards and regulations.
RF ENERGY EXPOSURE AND PRODUCT SAFETY GUIDE
This 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 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.
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, Bundesnetzagentur
...).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.

sible for compliance may void the user’s authority granted by the local
government radio management departments to operate this radio and
should not be made. To comply with the corresponding requirements,
transmitter adjustments should be made only by or under the supervi-
sion of a person certified as technically qualified to perform transmitter
maintenance and repairs in the private land mobile and fixed services
as certified by an organization representative of the user of those
services.
Replacement of any transmitter component (crystal, semiconductor,
etc.) not authorized by the local government radio management depa-
rtments equipment authorization for this radio could violate the rules.

RF Exposure Information
• DO NO
T operate the radio without a proper antenna attached, as this
may damage the radio and may also cause you to exceed RF expos-
ure limits. A proper antenna is the antenna supplied with this radio by
the manufacturer or an antenna specifically authorized by the manuf-
acturer for use with this radio, and the antenna gain shall not exceed
the specified gain by the manufacturer declared.
• DO NO
T transmit for more than 50% of total radio use time, more
than 50% of the time can cause RF exposure compliance requirements
to be exceeded.
• During transmissions, your radio generates RF energy that can
possibly cause interference with other devices or systems. To avoid
such interference, turn off the radio in areas where signs are posted
to do so.
•
The device complies with RF specifications when the device used at
5mm from your body. Third-party belt-clips, holsters, and similar acc-
essories used by this device should not contain any metallic compon-
ents. Body-worn accessories that do not meet these requirements may
not comply with RF exposure requirements and should be avoided.
• DO NO
T operate the transmitter in areas that are sensitive to
electromagnetic radiation such as hospitals, aircraft, and blasting
sites.
Avoid Choking Hazard
Small Parts. Not for children under 3 years.
Protect your hearing:
• Use
the lowest volume necessary to do your job.
•
Turn up the volume only if you are in noisy surroundings.
•
Turn down the volume before adding headset or earpiece.
• Limit the amount of time you use headsets or earpieces
at high volume.
• When using the radio without a headset or earpiece, do
not place the radio's speaker directly against your ear
• Use careful with the earphone maybe possible
excessive sound pressure from earphones and
headphones can cause hearing loss
