Use this menu to configure geographic information for each system or site. With this information and a standard NMEA GPS input, the scanner can automatically change which systems, sites and channel groups it scans as you change location. You must set the location information if you want to use Location-based Scanning.
Set Latitude and Set Longitude
Enter the latitude and longitude of the center of this system or site. You can use any geographical coordinates as the center, but most often it will be the physical location of the antenna, the center of a city, county, or other geopolitical territory, or some combination of the two.
Geographical coordinates can be represented in a few different ways. The two most common representations are DMS and Deg.
DMS breaks the coordinate into Degrees, Minutes, and Seconds. This is typically represented like: 44° 58' 12.79" N. Your scanner uses this format.
Decimal degrees simply use the degrees expressed as a decimal number. 44° 59' 12" equates to 44.97381 Degrees. Mathematically, you can change DMS to Deg using the formula DDD + MM/60 + SS.ss/3600. You would perform the reverse calculation to convert Deg to DMS.
To more easily convert Decimal Degrees to the DDD° MM' SS.sss" format or vice versa, see the converter at this
link.
Set Range
Enter the maximum distance from the center that this site or channel will be active. As long as your position is within the radius you enter here, the scanner monitors this site or channel; when you leave the channel range, the scanner locks out this site or channel. The scanner treats the number you enter here as miles or kilometers depending on the value you selected in the Set Unit field in the Set GPS Format menu (under the main Settings menu). Enter a range from 0.5 through 125.0 mi/km, in 0.5 mi/km steps.
Set GPS Enable
(A GPS unit must be connected)
Turn this feature on if you want the scanner to lock out this site or channel group when you leave the range and enable the site or channel group when you are within the range.
