FCC Licensing Information

This device complies with part 15 of

General Specifications

The PR 955 DX radio operates on General Mobile Radio Service (GMRS) frequencies which require a Federal Communications Commission (FCC) license.

For licensing information and application forms, please call the FCC Hotline at:

1-800-418-FORM

(Request form #159 and form #605) If you have any questions regarding the license application, you can contact the FCC directly at:

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 parts 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.

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
