Thank you for purchasing the
RadioShack 22 Ch GMRS/FRS
Two-Way Radio. This is a lightweight,
palm-sized radio, which provides short-
range voice radio communication (up to
five miles) to let families and groups
keep in touch with each other on
specific reserved channels.
Your radio has 22 channels and 38
different quiet codes, which you can
use to talk with another person who has
aGMRSorFRSradiosettothesame
frequency as your radio. Your radio
also has 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 radio
(neither supplied, available at your local
RadioShack store).
Your radio’s display has a backlight that
turns on for about five seconds when
you press any key except
PTT.
