Just bought new battery, need toknow how to get phone to work again

When you get new batteries for a cordless phone you need to let them charge over night. If you don't the battery will lose its charge much quicker. Now start by charging the batteries followed my plugging the base unit into the phone jack and the electrical outlet. The base unit is what sends out the signals to all the phones and is where your answering machine is located. Once the base is plugged in to the electrical socket and phone jack your phones should start receiving signal again. Make sure the batteries in the phones themselves are plugged in firmly and properly.
