I think the scanner can behave like a Minitor, except for one feature.
For the equivalent of Minitor's Monitor, which is "open" listening to all transmissions, then you'd put the scanner in the Hold mode, and scroll to the frequency for fire dispatching.
For the equivalent of Minitor's Selective Call, where the Monitor activates only when the programmed tone group(s) are transmitted, then the scanner should be in Fire Tone Out operation.
Unfortunately the scanner doesn't do Minitor's Silent Scanning, where the Minitor listens to two different fire dispatching frequencies and if the programmed tone groups are transmitted on either of the two frequencies, the scanner alerts.
