WARNINGS
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 freque-
ncies, 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 responsible 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 supervision 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 departments equipment
authorization for this radio could violate the rules.
FCC Requirements
• This device complies with part 15 of the FCC Rules. Operation is subject to the
following two conditions:
(1) This device may not cause harmful interference, and
(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 interfer-
ence to radio communications. However, there is no guarantee that interference
• 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 extended 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
• Do not use charger outdoors or in moist environments, 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 damaged in any
way.
• Do not place a portable radio in the area over an air bag or in the air
bag deployment area. The radio may be propelled with great force
and cause serious injury to occupants of the vehicle when the air bag
inflates.
