IMPORTANT NOTICE: FCC LICENSE REQUIRED 

This two-way radio operates on GMRS (General Mobile Radio Service) frequencies 
which require an FCC (Federal Communications Commission) license. A user must be 
licensed prior to operating on Channels 1 through 7 on high power or 15 through 
22, which comprise the GMRS channels of this radio. Serious penalties could result for 
unlicensed use of GMRS channels, in violation of FCC rules. Operation of this radio is 
subject to additional rules specified in 47 C.F.R. Part 95. 
Licensed users will be issued a call sign by the FCC, which should be used for station 
identification when operating this radio. GMRS users should also cooperate by engaging 
in permissible transmissions only, avoiding channel interference with other GMRS users, 
and being prudent with the length of their transmission time. 
For licensing information and application forms, please call the FCC Hotline  
at 800-418-FORM. Request form #159 and form #605. Questions regarding  
the license application should be directed to the FCC at 888-CALL-FCC.  
Additional information is available on the FCC’s website at www.fcc.gov.
Channel 1 through 7 on low power and channels 8 through 14 comprise the  
FRS (Family Radio Service). No license is required to operate on the FRS.

Safety Information for microTALK Radios

Your wireless handheld portable transceiver contains a low power transmitter.  
When the talk button is pushed, it sends out radio frequency (RF) signals.  
The device is authorized to operate at a duty factor not to exceed 50%.  
In August 1996, the Federal Communications Commissions (FCC) adopted  
RF exposure guidelines with safety levels for handheld wireless devices. 

Important

FCC RF Exposure Requirements: For body-worn operation, this radio has  
been tested and meets the FCC RF exposure guidelines when used with Cobra 
accessories supplied or designated for this product. Use of other accessories  
may not ensure compliance with FCC RF exposure guidelines. Use only the supplied 
antenna. Unauthorized antennas, modifications or attachments  
could damage the transmitter and may violate FCC regulations. 

Normal Position

Hold the transmitter approximately 2 inches from your face and speak in a normal 
voice, with the antenna pointed up and away.

Important:

 Please note that Cobra GMRS models with 15 Channels  

may designate different channel numbers for the same frequency.  

For example, a Cobra 15 Channel GMRS model would need to be  

tuned to Channel 11 in order to communicate with a 22 Channel  

GMRS tuned to Channel 15. Please refer to the chart below for  

channel/ frequency number compatibility. 

A =  Channel No. for 22 Channel FRS/GMRS Models

B =  Channel No. for 15 Channel GMRS Models
