Claim 7

A paging receiver as claimed in any of claims 1 to 5, wherein said decoder means and annunciation mode switching means comprise a one-chip central processing unit.

Claim 8

A paging receiver comprising: detector means for producing a detection pulse when detected a page signal which is assigned to said receiver; and an annunciation control means responsive to said detection pulse for sequentially driving two different annunciator means for a first and a second predetermined period of time, respectively.

Claim 9

A paging receiver comprising: detector means for producing a detection pulse when detected a page signal which is assigned to said receiver; and an annunciation control means responsive to said detection pulse for sequentially driving two different annunciator means for a first and a second predetermined period of time, respectively.

Claim 10

A paging receiver as claimed in claim 7, wherein said two different annunciator means comprise a tactile and an audible annunciator means, respectively.

Claim 11

A paging receiver as claimed in claim 7 or 8, wherein said annunciation control means comprises a mode switch timer responsive to said detection pulse for counting said first predetermined period of time, and an auto-reset timer responsive to said detection pulse for counting a period of time which is a sum of said first and second predetermined periods of time.

Claim 12

A paging receiver as claimed in claim 7 or 8, further comprising a reset switch means for producing a manual reset pulse, said annunciation control means stopping one of said two annunciator means which is in operation, in response to said manual reset pulse.

Claim 13

A paging receiver as claimed in claim 8, wherein said tactile annunciator means comprises a vibrator means for generating vibration, and said audible annunciator means comprises a speaker means for producing audible sound.

Claim 14

A paging receiver as claimed in claim 11, wherein said vibrator means comprises an eccentric motor and a motor driver for driving said motor, and wherein said speaker means comprises a speaker and a speaker driver for driving said speaker.

Claim 15

A paging receiver as claimed in any of claims 7 to 12, further comprising a function select switch for generating an annunciation sequence switch pulse, said annunciation control means switching a drive sequence of said two different annunciator means in response to said annunciation sequence switch pulse.

Claim 20

A method as claimed in claim 15, further comprising the steps of manually generating a reset pulse, and stopping the annunciator means driven in response to said reset pulse and irrespective of whether said first and second timers are over.
