Before using your new GMRS-310 radio,
please read this User’s Guide so that you can
take full advantage of all the features of the
radio.

The GMRS-310 is a lightweight, palm-sized
radio that you can carry almost anywhere;
while hunting, fishing, camping, hiking, at
shopping malls, amusement parks, or sports
events to keep in touch with family and friends.

Using the GMRS-310 does not require a
monthly service fee - the radio can be used
anywhere as
allowed by the FCC.

To insure proper communications with other
radios, they must be on the same channel and
CTCSS (Continuous Tone Controlled Squelch
System) sub-code as your GMRS-310.
The channel is the radio frequency wave your
radio uses to transmit and receive on. The

CTCSS sub-code helps reduce unwanted
chatter on the same radio channel, and gives
you more channel choices for increased
privacy.

The GMRS-310 operates on both General
Mobile Radio Service (GMRS) and Family
Radio Service (FRS) channels. Refer to the
Channel Frequency and Sub-Code Lists
(Sections 15 and 16) for channel and CTCSS
sub-code choices.

The Federal Communications Commission
(FCC), with its action in General Docket 93-62,
November 7, 1997, has adopted a safety
standard for human exposure to Radio
Frequency (RF) electromagnetic energy
emitted by FCC regulated equipment. This
radio subscribes to the same safety standard
for the use of its products. Proper operation of
this radio will result in user exposure far below
