Warnings
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/](http://www.who.int/en/)
Local Government Regulation
When radios are used as a consequence of employment, the Local Government
Regulations require 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 an 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

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 an 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 is 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.
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 a 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 care with the earphone may be 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 another container with metal objects
**Long transmission
**
When the transceiver is used for long transmissions, the radiator and chassis will become hot.
