RF ENERGY EXPOSURE AND PRODUCT SAFETY GUIDE
This radio uses electromagnetic energy in the radio frequency (RF) spectrum to provide communicat-
ions 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.

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 exposure limits. A proper antenna is the antenna supplied with
this radio by the manufacturer or an antenna specifically authorized by the manufacturer 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 accessories used by this device should not contain any metallic
components. 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.

Precautions

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 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, partic-
ularly 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.
To reduce risk
• Pull by the plug rather than the cord when disconnecting the charger.
• Unplug the charger from the AC outlet before attempting any maintenance or cleaning.
• Contact Retekess for assistance regarding repairs and service.
• The adapter shall be installed near the equipment and shall be easily accessible
• Risk of explosion if battery is replaced by an incorrect type. Dispose of used batteries
