The information listed above provides the user with the information needed to make him or her aware of RF exposure,
and what to do to as-sure that this radio operates with the FCC RF exposure limits of this radio.
Electromagnetic Interference/Compatibility
During transmissions, TYT Electronics Co., Ltd. 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. DO NOT operate the transmitter in
areas that are sensitive to electromagnetic radiation such as hospitals, aircraft,and blasting sites.
Occupational/Controlled Use
The radio transmitter is used in situations in which persons are exposed as consequence of their employment provided those persons
are fully aware of the potential for exposure and can exercise control over their exposure.
Attention:
This radio complieswith IEEE and ICNIRP exposure limits for occupational/controlled RF exposure emvironment at operating duty factors
of up to 50% and is authorized by the FCC for occupational use only. An appropriate warning lable is affixed to all units. In order to
comply with RF exposure requirements, a minimum distance of 2.5cm must be maintained when held-to-face, and body-worn
operations are restricted to the approved original acessories (belt clip)a minimum distance of 0cm. Do not use this device when antenna
shows obvious damages.
This product is compliance to FCC RF Exposure requirements and refers to FCC website
https://apps.fcc.gov/oetcf/eas/reports/GenericSearch.cfm search for FCC ID: POD-DMR6 to gain further information include SAR Values.
Use the two way radio in the environment with the temperature between -10℃~ 40℃, otherwise, it may damage your two way radio.
It can be operating under 2000m.
This EUT is compliance with SAR for controlled exposure limits in IC RSS-102 and had been tested in accordance with the measurement
methods and procedures specified in IEEE 1528 and IEC 62209. This equipment should be installed and operated with a minimum

15
distance of 2.5cm must be maintained when held-to-face, and body-worn operations are restricted to the approve doriginal acessories.
