Rino ® 120 Owner’s Manual 97APPENDIX > WHAT IS FRS?Channel scan allows your FRS radio to scan all FRSfrequencies for signals. After scanning briefly to see whatchannels other users are on, simply set your FRS radios toan unused channel and enjoy less interference. For greaterprivacy, some FRS radios have a voice scramble feature.This feature causes your message to sound garbled toother FRS users that are not part of your group. However,it does not guarantee your conversations will be 100percent private and secure. Other casual FRS users willnot hear your messages, but users with similar radios ormore technically-oriented users can still monitor yourconversations.FRS LimitationsIf you are operating in an urban environment or invarying terrain such as canyons or mountains, somefeatures act as obstructions limiting the maximumreception range of your FRS radio. The UHF FRSfrequencies are “line of sight,” meaning that the signalsdo not follow the surface of the earth, but instead radiatein a straight line from the transmitting antenna. If thereis an obstruction between the transmitting FRS radio andthe receiving FRS radio, the signal will not be received.Smaller obstructions, such as trees, cars, and even crowdsof people cause some loss of signal, resulting in reducedmaximum range.GMRSThe use of a GMRS (General Mobile Radio Service)radio requires an FCC license. No license is required inCanada to operate on GMRS channels. The operatingfrequency of GMRS ranges from 462.550 to 462.725MHz. GMRS radios can use repeater channels (15R–22R)and repeater towers to extend the range of the operation.A repeater tower simultaneously receives GMRS signalson a 467 MHz frequency and then rebroadcasts thesignal on a 462 MHz frequency. Refer to the “FrequencyCharts” for a complete list of each channel’s frequency.GMRS repeater channels are not approved for use by theCanadian government, so they are disabled on Rino 120units sold in Canada.
