So I ordered a used Motorola Minitor 2 pager from a company in New York. I guess I just wanted to have a piece of history around and had them set it up for my counties dispatch frequency and departments pager tones. Most of the time it will go off when my department is toned out but there’s been times it hasn’t. There was a strong signal to the pager at these times and my other pager went off so I know the dispatch center was hitting the right tones. Should I open the pager up and see if the filters are in all the way ? Maybe pull them out and reincert them ? Thank you for any help
