Family Radio Service

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® FRS 120
is a great way for friends or family to have fun and
be safe 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. 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.

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®

1.

Belt Clip

2.

Wrist Strap

3.

Two microTALK® SNAP™™ removable fronts.
