They will need charging first, I think. They come with 4 AAA (or slightly smaller) batteries each. You put the batteries in each radio and sit them in the chargers. There isn't an indicator on the cradle to tell you when they are fully charged, and the battery indicator on the radio isn't reliable. To avoid the memory effect, you need to fully charge them (about 12 hours), and then each time, use them until they are out of juice and then fully charge them again. It isn't recommended to have them on while charging. After a few days, we should get an idea of how long we can have them on.
Do we have our own handles, or do we have a handle for the job we're doing?
