Note that this is solely a pager programmer, used to set frequencies, tones, alerts, etc. It cannot be used to change the firmware in a pager. It also doesn't support the Engineer Mode special software used by shops to ahcnge the pager's frequency sub-band, channel capacity, etc.
The Minitor pagers are very sensitive receivers, and can be used for other purposes besides paging, assuming you can program it yourself and don't have to pay someone $15-$20 every time you want it re-programmed.
This programmer works with the standard Motorola Minitor III/IV programming PC software and also with the Motorola Minitor V programming PC software . I am NOT providing this software, but you can find it free online.
