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? Cobra’s MicroTalk 3 is a great
way for friends or family to increase their f u n – a n d
s a fe 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. All of these 14 channels are easily
accessed on your Cobra FRS radio. These chan­nels are in the UHF (Ultra High Frequency) band
which means great penetration 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.

FCCWarnings

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 3

1. Removable Belt Clip

2. Wrist Strap
