Abstract
Abstract A radio pager and a method of writing information necessary for communication in a ROM (14) (Read Only Memory) of the radio pager (10) by using a ROM writer (20). The ROM writer determines whether or not it is ready to communicate with the pager and, if it is ready, sends a type code request signal to a CPU (15) incorporated in the pager. On receiving the type code request signal, the CPU (15) sends a type code signal representative of the type of the pager to the ROM writer. In response, the ROM writer identifies the type of the pager and then writes information necessary for communication in the ROM of the pager. <IMAGE>

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
131 words
A method of writing information necessary for communication in a ROM of a radio pager to which a particular type code is assigned by using a ROM writer, comprising the steps of: (a) confirming the connection of said radio pager and said ROM writer; (b) sending a type code request signal from said ROM writer to said radio pager; (c) sending, in response to said type code request signal, a type code signal representative of said particular type code from said radio pager to said ROM writer; (d) causing said ROM writer to identify the type of said radio pager in response to said type code signal; and (e) sending said information from said ROM writer to said ROM of said radio pager to thereby write said information in said ROM.
Claim 2
Dependent Claim
21 words
A method as claimed in claim 1, wherein said type code is stored in said ROM of said radio pager beforehand.
Claim 3
Dependent Claim
33 words
A method as claimed in claim 1 or 2 , wherein said information comprises said type code, an address assigned to said radio pager, a reception control method, and contents of standardized sentences.
Claim 4
Independent Claim
40 words
A method as claimed in any of claims 1 to 3, wherein step (a) comprises (f) setting up a ROM write mode in said radio pager after the completion of the connection of said radio pager and said ROM writer.
Claim 5
Independent Claim
101 words
A method as claimed in any of claims 1 to 4, further comprising the steps of: (f) sending a first predetermined code from said ROM writer to said radio pager after confirming the connection of said radio pager and said ROM writer; (g) determining, in response to said first predetermined code, whether or not said radio pager is ready to write said information in said ROM and, if said radio pager is ready, sending a second predetermined code signal to said ROM writer; and (h) causing said ROM writer to execute step (b) in response to said second predetermined code signal.
Claim 6
Independent Claim
31 words
A method as claimed in any of claims 1 to 5, wherein said information is written to said ROM by said ROM writer via a CPU incorporated in said radio pager.
Claim 7
Dependent Claim
26 words
A method as claimed in claim 6, wherein said ROM writer and said CPU comprise respective connecting means for connecting said ROM writer and said CPU.
Claim 8
Dependent Claim
49 words
A method as claimed in claim 7, wherein said ROM writer further comprises type code requesting means for sending said type code request signal in step (b), and type identifying means for identifying the type of said radio pager in response to said type code signal in step (d).
Claim 9
Dependent Claim
26 words
A method as claimed in claim 7 or 8, wherein said CPU comprises type code sending means for sending said type code signal in step (c).
Claim 10
Dependent Claim
25 words
In a radio pager wherein information necessary for communication is written to a ROM therein, a particular type code is stored in said ROM beforehand.
Claim 11
Dependent Claim
24 words
A radio pager as claimed in claim 10, wherein said type code is outputted from said ROM in response to an external request signal.
