Garmin 520 Manual De Propietario

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.

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. 

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.
