RF ENERGY EXPOSURE AND PRODUCT SAFETY GUIDE
ATTENTION
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 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.

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:
WARNING
- 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
WARNING
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.
