Introduction Operation Customer Assistance Warranty General Specifications 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 = 22 Channel GMRS Channel No. Displayed B = Channel No. For 15 Channel GMRS Models C = Type of Radio Service D = Frequency in MHz E = Power in Watts ERP a = 3.0/2.0/0.5 (selectable) b = 0.5 B.
