Why won't my Angelcare AC420 Baby Monitor turn on?

If the power ON indicator (green light) does not light up and the display is not activated on the parent unit, there are a few potential reasons. The batteries may be low or improperly installed, so check or replace them, or recharge the parent unit. Also, ensure the AC adapters are properly connected and the electrical outlet is working. Finally, make sure the nursery unit is in the ON position (left wing on “-” position).
