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 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, as stipulated in the Communications Act’s Sections 501 and 
502 (amended). 

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.

Your wireless handheld portable transceiver contains a low power transmitter. 
When the PTT 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:
To maintain compliance with the FCC’s RF guidelines, hold the transmitter at least 
2 inches (5 centimeters) from your face and speak in a normal voice, with the antenna 
pointed up and away. If you wear the handset on your body while using the headset 
accessory, use only the Cobra

®

supplied belt clip for this product and ensure that the 

antenna is at least 1 inch (2.5 centimeters) from your body while transmitting. If the 
distance between the antenna and the body is LESS THAN 1.0" (2.5 cm), DO NOT USE 
THIS DEVICE IN THE BODY WORN CONFIGURATION. 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" from your face and speak 
in a normal voice, with the antenna pointed up and away.
