Appendix > About FRS/GMRS Radio Channel scan allows your FRS radio to scan all FRS frequencies for signals. After scanning briefly to see what channels other users are on, set your FRS radios to an unused channel and enjoy less interference. For greater privacy, some FRS radios have a voice scramble feature. This feature causes your message to sound garbled to other FRS users that are not part of your group. However, it does not guarantee your conversations will be 100 percent private and secure. Other casual FRS users will not hear your messages, but users with similar radios or more technically-oriented users can still monitor your conversations. FRS Limitations If you are operating in an urban environment or in varying terrain, some features (such as canyons or mountains) 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 Radio The use of a GMRS (General Mobile Radio Service) radio requires an FCC license (refer to the Web site http://www.wireless.fcc.gov/uls/ for details.) No license is required in Canada to operate on GMRS channels. The operating frequency of GMRS ranges from 462.550 to 462.725 MHz. GMRS radios can use repeater channels (15R-22R) and repeater towers to extend the range of the operation. A repeater tower simultaneously receives GMRS signals on a 467 MHz frequency and then rebroadcasts the signal on a 462 MHz frequency. Refer to the "Frequency Charts" for a complete list of each channel's frequency. GMRS repeater channels are not approved for use by the Canadian government, so they are disabled on Rino 520/530 units sold in Canada. Rino® 520/530 Owner's Manual 99
