Use this handy little tool to quickly test for polarity and other line conditions on any phone jack! Simply plug it in to test, and the LED readouts inform you of the status and any issues with Line 1 or 2; OK (Yellow), Reversed (Red), and Check (White). It's so easy to use, and incredibly compact and lightweight - it's a must have for any person interested in checking the operational status of phone lines. What's more, there's no batteries needed to power this unit as the results depend on the measure of electricity on the phone lines!
