The Motorola pager was a small radio receiver that delivered a message individually or widespread to those carrying the device.
This organization was responsible for a fixed industrial norm sequence of 5 selective call tones.
The device was in use to alert individuals or groups of persons within fire brigades or civil protection organizations.
Though the device was even smaller than the Pageboy I, its speaker was pointed upward so that the alerting beeps followed by a voice message always came through.
As many fire brigades switched over to digital equipment their outdated Pageboy II’s found their way to industrial safety & medical organizations.
