- 1). Press the "Talk" button and hold the button down while you speak. If you have more than two FRS radio units--one for your spouse, another for a child or teenager--it's usually best to say the name of the person you're calling.
- 2). Release the "Talk" button in order to listen for a response. FRS radios are "one way" communication: you must wait for the other person to finish speaking before they can hear you. When you press the "Talk" button, the radio will transmit, but not receive.
- 3). Try your radio in various locations aboard ship. FRS radios are short-range and walls, floors or ceilings can interfere with calls. Have your spouse try to call you when you are in your cabin and they are in the dining room or the ship's shopping area to find out how well the radios work in different locations aboard.
