      If your Uniden Cordless Telephone can't make or receive calls, ensure you're within the base's range and that the line isn't already in use for an outside call. Check the telephone line cord connections at both ends and verify the AC adapter is correctly plugged into the base and the wall outlet. Try disconnecting and reconnecting the AC adapter.
