TV can be, it needs to have the inverter turned on (assuming yours has one)
Your antenna needs to be tuned on (there is a switch on the side look for the king Jack on the celling) more blue lights the better, and a push switch above the sink in the cabinet. Once you turn the antenna on you will need to go into the menu setting of the TV and perform a Air Scan for channels.
Radio, I not sure how yours is set up, there is a switch right underneath that says Radio, toggle it one way an the radio will turn on.
