Uniden BCD996T 사용자 매뉴얼

The BCD996T uses data, supplied by an attached GPS unit, that lets the radio 
automatically unlock and lockout sites based on the geographical information you 
provide.

• Latitude (the center of the range or site)

• Longitude (the center of the range or site)

• Range (the radius of a circle around the latitude and longitude coordinates 

selected from up to 50 miles from that center).

You set the longitude and latitude to approximate the center of a geographic entity 
such as your local city. Then set the range to encircle that center point. By doing so 
the scanner automatically locks out reception of an area outside that circle.

All geopolitical areas are rarely perfect circles. You can accommodate these 
variations by entering multiple sites for the system, even though the system 
actually has only one site, and use different location settings for each of those 
additional sites.

Figure A shows, schematically, an ideal reception situation. The area almost 
matches the site area. But Figure B is more like the real world. How do you 
effectively match the narrow geographical area to the circular site transmission? 
Figure C shows the answer. You create multiple sites for the scanner. You program 
the longitude and latitude, and the range, of each of the three sites to more closely 
match the geographic area.
