A. FRS/GMRS FREQUENCY
ALLOCATION AND 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
B = Channel No. For 15 Channel GMRS Models
C = Type of Radio Service
D = Frequency in MHz
E = Power in Watts
a = 2.0/0.5 (selectable)
b = 0.5

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
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 (5 cm) from your face and speak
in a normal voice, with the antenna pointed up and away.
Note:
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
with parts other than those recommended by Cobra
regulations of part 95 of the FCC Rules, or violation of type acceptance requirements of
part 2 of the Rules.
