Abstract
Abstract A combined tone only and tone and voice multiple alert pager is provided which implements separate tone only and tone and voice alert modes in response to the reception of different predetermined signal codes. The pager also includes an audio monitor switch for monitoring audio frequency information received by the pager. During the tone only alert mode the operation of the audio monitor switch is inhibited and only a distinct audible alert tone is provided by the pager. During the tone and voice alert mode, a different audible alert tone is provided and this is automatically followed by audible voice information. Actuation of the audio monitor switch is also utilized to terminate the audible alert tone in the tone only mode whereas actuation has no effect on terminating the audible alert tone in the tone and voice alert mode. Release of manual pressure from the audio monitor switch is utilized to terminate the tone only and tone and voice alert modes but the tone and voice alert mode can only be terminated by operation of the audio monitor switch after the pager starts to provide the subsequent audio frequency information which automatically follows the tone and voice audible alert tone.
