The Family Radio Service Story

The Family Radio Service Story

Ever wish you could talk to someone who wasn’t
within earshot? Like contacting ski partners back
at the lodge? Or letting a friend know how to find
you in a busy mall? Cobr a’s MicroTalk FRS 100 is a
great way for friends or family to increase their
fun–and safe ty – by staying in touch while on the go.

The FCC (Federal Communications Commission)
has created 14 license free frequency bands ,
or channels, called Family Radio Service (FRS) 
frequencies. Two of these 14 channels (channel 
8 and 13) are easily accessed on your Cobra FRS
radio. These channels are in the UHF (Ultra High
Frequency) band which means great penetr ation
through buildings, thick forests, hills, and other
dense structures. They are also FM (Frequency
Modulation) signals which means crystal clear
reception even in crowded noisy environments.

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 .

Included with your MicroTalk
