My church plant uses the D3540 pager - https://www.microframecorp.com/d3540-4-digit-wireless-visual-pager-display
We have to setup and tear down the pager system every week. We have to manually wire the 2-wire power connector into the green connector - shown below and at the link above - and it's a finicky/difficult process. The wire is always loose, and wiring is stressful for some of our setup team.
Is there some plug-in adapter replacement I can use to make this better? I'd love to convert it to just use a standard A/C adapter, but I'll take any improvements.
