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 comm
unicate with a 22 Channel GMRS
tuned to Channel 15. Please refer to the
chart below for channel/ frequency
number compatibility.

Operation
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, 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.
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 two inches from your face and
speak in a normal voice, with the antenna pointed up and away.
This device complies with part 15 of the FCC Rules. Operation is subject
to the following two conditions: (1) This device may not cause harmful
interference, and (2) this device must accept any interference received,
including interference that may cause undesired operation.
FCC Warnings: Replacement or substitution of transistors, regular diodes or
other par
ts of a unique nature, with parts other than those recommended by
Cobra may cause a violation of the technical regulations of part 95 of the FCC
rules, or violation of type acceptance requirements of part 2 of the rules.
