FRS?

Channel scan allows your FRS radio to scan all FRS

frequencies for signals. After scanning briefly to see what

channels other users are on, simply set your FRS radios to

an unused channel and enjoy less interference.

FRS Limitations

If you are operating in an urban environment or in

varying terrain such as canyons or mountains, some

features act as obstructions limiting the maximum

reception range of your FRS radio. The UHF FRS

frequencies are “line of sight,” meaning that the signals

do not follow the surface of the earth, but instead radiate

in a straight line from the transmitting antenna. If there

is an obstruction between the transmitting FRS radio and

the receiving FRS radio, the signal will not be received.

Smaller obstructions, such as trees, cars, and even crowds

of people cause some loss of signal, resulting in reduced

maximum range.

GMRS

The use of a GMRS (General Mobile Radio Service)

radio requires an FCC license in the U.S. No license is

required in Canada to operate on GMRS channels. The

operating frequency of GMRS ranges from 462.550 to

462.725 MHz. Refer to the “Frequency Charts” for a

complete list of each channel’s frequency.
