RF exposure levels. In addition, manufacturers also

recommend specific operating instructions to users of 

walkie talkie. 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 walkie talkie are used as a consequence of em-

pl

oyment, 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 Retevis walkie talkie has a RF

Exposure Product Label. Also, your Retevis user 

manual, or separate safety booklet includes information 

and operating instructions required to control your RF 

exposure and to satisfy compliance requirements.

 

Radio License

Governments keep the radios in classification, most

of the classified walkie-talkie need to get local

government License, and operation is allowed. The

detailed classification and the use of your two radios,

please contact the local government radio management 

departments. For the following specified classification: 

the USA FRS, Australian CB, the individual license is 

not required.  

Compliance with RF Exposure Standards (If

appropriate, Reference to the actual product’s

Safety Marking)

Your Retevis walkie talkie is designed and tested to 

comply with a number of national and International

standards and 

guidelines (listed below) for human

exposure to radio frequency electro-magnetic energy. 

FCC ID 

The FCCID means: This radio complies with the IEEE

(FCC) and ICNIRP exposure limits for occupational

/controlled RF exposure environments at operating

duty 

factors of up to 50% talk-50% listen and is 

approved for occupational use only.

IC ID 

This device complies with Industry Canada 

license-exempt 

RSS standard(s). Operation is subject 

to the following two conditions:

(1) This device may not cause interference, and

(2) 

This device must accept any interference, including

     interference that may cause undesired operation of 

     the device.

In terms of measuring RF energy for compliance with 

these exposure guidelines, your radio generates

measurable RF energy only while it is transmitting

(during talking), not when it is receiving (listening) or

 

in standby mode.

Note: The approved batteries, supplied with this radio, 

          are 

rated for a 5-5-90 duty factor (5% talk-5% 

          listen-90% standby) even though this radio 

          complies with FCC occupational exposure limits 

          and may operate at 

duty factors of up to 50% t

alk.
