INTRODUCTION
Thank you for purchasing a pair of
RadioShack 22 Ch GMRS/FRS Two-
way Radios. They provide short-range
(up to about 5 miles) voice radio
communication to let families and
groups keep in touch with each other
on specific reserved channels.
You can use these lightweight, palm-
sized radios to talk with another person
who has a GMRS/FRS radio set to the
same frequency as your radios.
Your radios have 22 channels and 38
different quiet codes. Your radios also
have auto-squelch, so you will not hear
anything on a channel unless someone
is transmitting nearby on the same
channel.
You can connect an optional speaker/
microphone and earphone to the radios
(neither supplied, available at your local
RadioShack store).
Your radio’s display has a backlight that
turns on for about 5 seconds when you
press any key except
PTT .
