I don't know how to test/ use them. When I plugged them in their charger, the red light "charging" is on.
About a minute later, the light is yellow "stand by". They make loud noise when I plugged them in the charger. This item is in the category "Consumer Electronics\Radio Communication\Walkie Talkies, Two-Way Radios".
