Compatibility
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 GMRS Models

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.
