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.

Licensing

For Products Used in the U.S.A.

FCC Licensing 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 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 Communication 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.

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.
