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.
Unauthorized modification and adjustment
Changes or modifications not expressly approved by the party respon-
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.
FCC Requirements:

RF Exposure Information
• DO NOT 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 NOT 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 NOT 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

Note: Exposure to loud noises from any source for exten-
ded periods of time may temporarily or permanently affect
your hearing. The louder the radio's volume, the less time
is required before your hearing could be affected. Hearing
damage from loud noise is sometimes undetectable at
first and can have a cumulative effect.
Avoid Burns
Antennas
• Do not use any portable radio that has a damaged
antenna. If a damaged antenna comes into contact with
the skin when the radio is in use, a minor burn can result.
Batteries (If appropriate)
• When the conductive material such as jewelry, keys or
chains touch exposed terminals of the batteries, may
complete an electrical circuit (short circuit the battery)
and become hot to cause bodily injury such as burns.
Exercise care in handling any battery, particularly when
placing it inside a pocket, purse or other container with
metal objects
Long transmission
• When the transceiver is used for long transmissions,
the radiator and chassis will become hot.
Safety Operation
Forbid

use only in dry locations/conditions.
• Do not disassemble the charger, that may result in risk
of electrical shock or fire.
• Do not operate the charger if it has been broken or
