Abstract
Abstract A radio receiver having a theft prevention system using an anti-theft code, wherein a region code, corresponding to various regions in the world, is inputted by a user to set the receiver to the proper receiving standards of the selected region, and wherein an anti-theft code is inputted by the user. If the anti-theft code inputted by the user corresponds with a previously stored anti-theft code, the receiving standards are set within the receiver and the receiver is enabled.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
139 words
A radio receiver having a theft prevention system using an anti-theft code, said theft prevention system comprising: first means for preliminarily storing region codes corresponding to various regions in the world and for preliminarily storing receiving standards in said various regions corresponding to said region codes; second means for preliminarily storing a first anti-theft code; means for inputting one of said region codes stored in said first storing means and for inputting an anti-theft code; and means for switching said receiving standards according to said one of said region codes when one of said region codes is input into said inputting means and aftter an anti-theft code is input into said inputting means which corresponds with said first anti-theft code, said switching means coupled to said first storing means, to said second storing means, and to said inputting means.
Claim 2
Dependent Claim
139 words
A radio receiver having a theft prevention system using an anti-theft code, said theft prevention system comprising: first means for preliminarily storing region codes corresponding to various regions in the world and for preliminarily storing receiving standards in said various regions corresponding to said region codes; second means for preliminarily storing a first anti-theft code; means for inputting one of said region codes stored in said first storing means and for inputting an anti-theft code; and means for switching said receiving standards according to said one of said region codes when one of said region codes is input into said inputting means and aftter an anti-theft code is input into said inputting means which corresponds with said first anti-theft code, said switching means coupled to said first storing means, to said second storing means, and to said inputting means.
Claim 3
Dependent Claim
173 words
A radio receiver having a theft prevention system using anti-theft code, said theft prevention system comprising: first means for preliminarily storing region codes corresponding to various regions in the world and for preliminarily storing receiving standards in said various regions corresponding to said region codes; second means for preliminarily storing a first anti-theft code; means for inputting one of said region codes stored in said first storing means and for inputting an anti-theft code; collating means coupled to said first storing means, to said second storing means, and to said inputting means; means for switching said receiving standards according to one of said region codes when said one of said regions codes is input into said inputting means, said switching means coupled to said collating means; and means for starting said receiving after said receiving standards have been switched in accordance with the input of said one of said region codes and after an anti-theft code is input which corresponds with said first anti-theft code, and starting means coupled to said collating means.
Claim 4
Dependent Claim
